Answer:
15x +6y = 21. is equal to 07x +6y = -3. is equal to 0Step-by-step explanation:
15x +6y = 2 is equal to 0 because when we move the constant to the left and divide both sides of the equation by 3 we get:
5x + 2y - 7 = 0Same with 7x +6y = -3, when we move the constant to the left and sum the two opposites equal to 0 it give us:
7x + 6y + 3 = 0how do I find the area with only the height and diameter? HELP QUICK PLS!!
Answer:
The formula for the area of a circle is A = π r2, where r is the length of the radius of a circle. We can use our knowledge that a diameter is made up of two radii to understand that r = d/2. With this knowledge, you can rewrite the formula for the area of a circle as A = π (d/2)2.
Step-by-step explanation:
Angle 1 and angle 2 form a linear pair. If the measure of angle 1 = (5x+9)º and
the measure of angle 2 = (3x+11)º, find the measure of each angle.
X =
angle 1 =
angle 2 =
- linear pairs are supplementary, meaning they add up to 180°
5x + 9 + 3x + 11 = 180
8x + 20 = 180
8x = 160
x = 20
- now plug in.
angle 1: 5(20) + 9 = 100 + 9 = 109°
angle 2: 3(20) + 11 = 60 + 11 = 71°

You and 3 friends decide to split a box
of one dozen donuts. Together, the
amount spent for the donuts is $17.45. If it costs $1.25 to park, how much did each donut cost per person?
WRITE AN EQUATION and solve.
Please hurry
Thx
Answer:
Step-by-step explanation:
Number of individuals = 4
Cost of dozen donuts with transport = $17.45 + $1.25
= $18.7
Since there are 12 pieces in a dozen pack of donuts, then the amount of each donut is:
= $18.7/ 12
= $1.56
So, if four people share a dozen donut, each person will have:
= 12/4
= 3 donuts each
and the price each person will pay for the three donuts will be:
= $1.56 × 3
= $4.68

2) A pound and-a-half of candy costs $1.65. Find the cost of one pound.
Answer:
1.10
Step-by-step explanation:
1 pound and 1/2=1.65
1/3 of 1.65 is 0.55.
1/2 is 0.55
so 1 pound is 0.55 times 2 which is 1.10

In the equation f(x) = 3(x – h) 2+ k, what does (h,k) tell?
Answer:
(h,k) shows the coordintes of the turning point.
Answer:
coordinates of the vertex
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = 3(x - h)² + k ← is in vertex form
with vertex = (h, k )

The profits of a company are found by subtracting the company's costs from its revenue. If a company's cost can be modeled by 10x + 130,000 and its revenue can be modeled by
50x -0.00047x^2
, what is an expression for the profit?
9514 1404 393
Answer:
P = -0.00047x^2 +40x -130,000
Step-by-step explanation:
Profit is found by subtracting the company's costs from its revenue.
P = R - C
P = (50x -0.00047x^2) -(10x + 130,000)
P = -0.00047x^2 +40x -130,000

Answer:

Step-by-step explanation:
Key skills needed: Proportions, Cross multiplication, One variable Equations, Multiplication
1) Since this is a proportion, we need to cross multiply. A proportion is just 2 fractions equal to each other in this format.
---> Cross multiplication is when you multiply the first fraction's numerator by the second fraction's denominator, and you multiply the first fraction's denominator by the second fraction's numerator.
---> You set these products equal to each other.
2) So if we cross multiply it would be: 3(3x+5) = 5(3-2x)
---> If you multiply everything out, it would be --> 9x + 15 = 15 - 10x
3) Move the x terms to one side and the numbers to the other side
---> 9x + 10x = 15-15
4) Combine like terms (9x+ 10x= 19x) (15-15=0) 19x = 0
5) Divide by 19 and x=0.

Answer:
AB is 104
Step-by-step explanation:
In the given figure
∵ CE bisects the segment AB
→ That means CE intersects AB at the midpoint of AB
∵ CE ∩ AB at point F
∴ F is the midpoint of AB
→ The midpoint of a segment divides it into two equal parts
∵ The point F divides AB to FA and FB
∴ FA = FB
∵ FA = 7x + 10
∵ FB = 9x - 2
→ Equate them
∴ 9x - 2 = 7x + 10
→ Add 2 to both sides
∵ 9x - 2 + 2 = 7x + 10 + 2
∴ 9x = 7x + 12
→ Subtract 7x from both sides
∵ 9x - 7x = 7x - 7x + 12
∴ 2x = 12
→ Divide both sides by 2
∴ x = 6
→ Substitute the value of x in FA and FB
∵ FA = 7(6) + 10 = 42 + 10 = 52
∵ FB = 9(6) - 2 = 54 - 2 = 52
∵ AB = FA + FB
∴ AB = 52 + 52 = 104
∴ AB = 104
HELP: Can a triangle have 2 right angles in it? EXPLAIN your answer.
Answer:
No
Step-by-step explanation:
Because of the fact that the sum of the three interior angles of a triangle must be 180 degrees, a triangle could not have two right angles.
Answer:
No it cannot
Step-by-step explanation:
the sum of the angles of the triangles has to be 180 so if you have two right angles then the last angle has to be 0 which is not possible

How much did the pennies weigh in pounds (lbs)?
Answer:
3520 pounds
Step-by-step explanation:
First, we have to find how many pennies equal 2.2 lbs
By seeing that 1 penny equals 4 grams, we can divide 4 into 1,000
By doing this we can find out how many pennies equals 2.2 lbs
It is 250 pennies per 2.2 lbs
Now, it wants 400,000 pennies
So we can do 400,000/250
Which is 1600
1600*2.2 is 3520
So the answer is 3520 pounds

Step 1
30x-16=14 Equation/Question
Step 2
30x-16=14 Simplify
30x-16=14
Step 3
30x-16=14 Add 16 to sides
30x=30
Step 4
30x=30 Divide sides by 30
answer
x=1
Hope this helps
Step-by-step explanation: To solve for X, we'll need to move all terms that don't contain X to the right and solve.
1. Add 16 to both sides
30x - 16 + 16 = 14 + 16
30x = 30
2. Divide both sides by 30
[tex]\frac{30x}{30} =\frac{30}{30}[/tex]
Therefore, your answer is 1.
X = 1
