The perimeter of a rectangle is 53 inches. The combined length of the two shorter sides is 18 inches. What is the length of each of the longer sides? Complete the sentences to write an equation to model this problem.
Answer:
17.5 in
Step-by-step explanation:
Step one:
given
The perimeter of a rectangle is 53 inches
let the two shorter sides be the width w
so w+w= 18in
the two longer sides is L
L+L=2l
Step two:
but the expression for the perimeter of a rectangle is
P=2W+2L
53= 18+2L
53-18=2L
35=2L
divide both sides by 1
L=35/2
L=17.5

What is the result when 12x3 + 20x2 + 11x + 2 is divided by 3x + 2?
Answer: 3x + 2) 12x� + 20x� + 11x + 2
Divide the first term 12x� by 3x: %2812x%5E3%29%2F%283x%29=4x%5E2
and write 4x� above the 20x�:
4x�__________
3x + 2) 12x� + 20x� + 11x + 2
Multiply the 4x� by the (3x + 2) getting 4x%5E2%283x%2B2%29=12x%5E3%2B8x%5E2 and
write it under the first two terms and draw a line underneath:
4x�__________
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
Subtract %2812x%5E3%2B20x%5E2%29-%2812x%5E3%2B8x%5E2%29=12x%5E3%2B20x%5E2-12x%5E3-8x%5E2=12x%5E2,
and write 12x� under the line under 8x�, like this:
4x�__________
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x�
Now bring down the next term + llx and write in next to the 12x�
4x�__________
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
Divide the first term on the bottom 12x� by 3x: %2812x%5E2%29%2F%283x%29=4x
and write + 4x above the 11x at the top, like this:
4x� + 4x____
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
Multiply the 4x by the (3x + 2) getting 4x%283x%2B2%29=12x%5E2%2B8x and
write it under the first two terms and draw a line underneath:
4x� + 4x____
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
12x� + 8x
Subtract %2812x%5E2%2B11x%29-%2812x%5E2%2B8x%29=12x%5E2%2B11x-12x%5E2-8x=3x,
and write 3x under the line under 8x, like this:
4x� + 4x____
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
12x� + 8x
3x
Now bring down the last term + 2 and write in next to the 3x
4x� + 4x____
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
12x� + 8x
3x + 2
Divide the first term on the bottom 3x by the 3x at the left:
%283x%29%2F%283x%29=1 and write + 1 above the + 2 at the top,
like this:
4x� + 4x + 1
3x + 2) 12x� + 20x� + 11x + 2
12x� + 8x�
12x� + 11x
12x� + 8x
3x + 2
Multiply the + 1 by the (3x + 2) getting 1%283x%2B2%29=3x%2B2 and
write it under the two terms at the bottom and draw a line
underneath:
4x� + 4x + 1

12x� + 8x�
12x� + 11x
12x� + 8x
3x + 2
3x + 2
Subtract %283x%2B2%29-%283x%2B2%29=3x-3x=0,
and write 0 under the line under 2, like this:

12x� + 8x�
12x� + 11x
12x� + 8x
3x + 2
3x + 2
0
Now you are done and the answer is 4x%5E2%2B4x%2B1 and
since the remainder is 0 you do not have to put it over
the divisor 3x+%2B+2 and add it on like you do when
the remainder is not 0.

12 roses costs $45.60, so in order to find the cost of one rose you have to divide the cost of 12 roses by 12, which gives $3.80.
Now that you know the cost of one rose, you can write an equation that gives you the cost in terms of the total number of roses by multiplying the cost of one rose by the total number of roses (x). This equation should be C = 3.8x
To find how much 18 roses would cost, you plug 18 into the previous equation for x, which gives you $68.40
Answer/Step-by-step explanation:
1. Well, we know that a dozen roses costs $45.60. We also know that a dozen is the same as 12. To know how much 1 rose costs, we need to divide $45.60 by 12.
45.60 ÷ 12 = $3.80. Therefore 1 rose costs $3.80.
2. y = yx
This is because the total amount of roses equal the cost of each rose multiplied by the amount of roses.
3. To find out how much 18 roses costs, we need to multiply the amount of one rose by 18. So, 3.80 x 18 = $68.4
Hope the helps! :D

For every boy in an advanced math course there are 3 girls who are taking the course.
If 32 students are enrolled in the course, how many students are girls?
A:24
B:26
C:28
D:21
Answer:
If 32 students are enrolled in the course, there would be 24 girls.
Step-by-step explanation:
Given that For every boy in an advanced math course there are 3 girls who are taking the course.
It means if there are four students in the class. There would be 3 girls and 1 boy. Thus, 75% of the students are girls.
Given that there are 32 students enrolled in the course.
so
75% of 32 = 75/100 × 32
= 24
Thus, if 32 students are enrolled in the course, there would be 24 girls.

The bag contained only red marbles and white marbles. If the ratio of red marbles to white marbles was 5 to 4, what fraction of the marbles were white? *Complete the statement by providing the correct response in number form, using / as the fraction symbol.
The fraction of white marbles is
Answer:
The fraction of white marbles is 4/9
Step-by-step explanation:
The fraction of white marbles is 4/9. This is because the ratio provided states that for every 5 red marbles in the bag there are 4 white marbles. Therefore, in a set of 9 total marbles (5+4) we can assume that exactly 4 of those marbles will be white since that is the ratio that has been provided. If there are a total of 18 marbles we can assume that exactly 8 will be white marbles, and so on. Each of which represent the fraction of white marbles in the bag as 4/9
If p (x)is equals to x cube minus x square + X + 1 find value of P (- 1)+ p(1) / 2
p(x) = x³ - x² + x + 1

if the measure of angle 6 is 28⁰ then the measure of angle 3 is
Answer: 62
Step-by-step explanation:
Every triangle’s angles add up to 180. since it’s a right triangle one of the angles is 90 degrees and the other is 28 degrees. so then you have to find the other angle which would made it add up to 180. which is 62.
28+90=118

Quadrilateral ABCD has vertices A(–1, –2), B(–1, 3), C(4, 3) and D(4, –2). It's dilated by a factor of 2 with the center of dilation at the origin. What are the coordinates of the resulting quadrilateral A'B'C'D'?
Given:
Quadrilateral ABCD has vertices A(–1, –2), B(–1, 3), C(4, 3) and D(4, –2).
It's dilated by a factor of 2 with the center of dilation at the origin.
To find:
The coordinates of the resulting quadrilateral A'B'C'D'.
Solution:
The figure dilated by a factor of 2 with the center of dilation at the origin. So, the rule of dilation is
[tex](x,y)\to (2x,2y)[/tex]
Using the above rule, we get
[tex]A(-1,-2)\to A'(2(-1),2(-2))=A'(-2,-4)[/tex]
[tex]B(-1,3)\to B'(2(-1),2(3))=B'(-2,6)[/tex]
[tex]C(4,3)\to C'(2(4),2(3))=C'(8,6)[/tex]
[tex]D(4,-2)\to D'(2(4),2(-2))=D'(8,-4)[/tex]
Therefore, the coordinates of the resulting quadrilateral A'B'C'D' are A'(-2,-4), B'(-2,6), C'(8,6) and D'(8,-4).

The measure of an angle is 47°. What is the measure of its complementary angle?
Answer: 90
Step-by-step explanation:
90 degrees. x=90-47=43 degrees.
Step-by-step explanation: We can find the measure of its complement
by taking 90 minus the measure of the original angle.
So we have 90 - 47 which is 43.
So the measure of its complement is 43°.

A scale drawing shows the distance between the bases as 2 inches. One inch on this drawing
equals how many feet?
Enter your response here:
Answer:
1 inch of drawing = 45 feet
Step-by-step explanation:
Given that:
Length between the bases on a baseball field = 90 feet
As per the scale drawing, the distance between the bases is equal to 2 inches.
To find:
Length of one inch on the drawing is equal to actual length of how many feet?
Solution:
First of all, let us learn about the scale drawings.
Scale drawings are a way to represent the big real world measurements on a paper.
Therefore, small measurements are used to represent the bigger real world measurements.
Here, it is given that:
2 inches on scale is equal to 90 feet of actual length.
Therefore,
1 inch on scale is equal to [tex]\frac{90}{2}[/tex] = 45 feet of actual length.
Therefore, 1 inch of drawing = 45 feet

Answer:
All 4 are solutions to the inequality.
Step-by-step explanation:
What we know:
The inequality requires that 48/f is less than or equal to 46.
Plug in each of the choices to see if that will work
48/12 ≤ 46
4 ≤ 46, so f = 12 will work.
48/-12 ≤ 46
-4 ≤ 46, so f = -12 will also work.
48/-3 ≤ 46
-16 ≤ 46, so f = -3 will work as well.
48/8 ≤ 46
6 ≤ 46, so f = 8 will work as well.
Since all 4 work, that means you should check all 4 choices on the question.
