Answer:
Step-by-step explanation:
All square angles are 90° exactly 90° so we can use that to your advantage. since "7x + 3" is one of the square's angles, that means 7x + 3 must equal 90°. (7x + 3)° = 90°.
7x + 3 = 90
7x = 90 - 3
7x = 87
7x/7 = 87/7
x = 87/7
Please help with this question!
Answer:
a. x = 5, AB = 14, BC = 8
Step-by-step explanation:
✔️Both triangles are similar, therefore their side lengths are proportional to each other.
Thus:
[tex] \frac{2x + 4}{x + 3} = \frac{7}{4} [/tex]
Cross multiply
[tex] 4(2x + 4) = 7(x + 3) [/tex]
[tex] 8x + 16= 7x + 21 [/tex]
Collect like terms
[tex] 8x - 7x = -16 + 21 [/tex]
[tex] x = 5 [/tex]
✔️AB = 2x + 4
Plug in the value of x
AB = 2(5) + 4
AB = 14
✔️BC = x + 3
Plug in the value of x
BC = 5 + 3
BC = 8

A $30 shirt is marked, "Get 25% off." What is the sale price of the shirt?
Answer:
$22.50
Step-by-step explanation:
First, we find how much we need to take off so our equation is:
30 x 0.25 = 7.5
So, we take 7.5 off of 30 which is:
30 - 7.5 = 22.5
So, the shirt is selling for $22.50
Hope this helps:)
-1/5x≤8
what is the aswer
Hey there!
“-1/5x ≤ 8”
MULTIPLY both sides by -5
-1/5x × -5 ≤ 8 × 5
CANCEL out: -1/5 × -5 because that gives you 1
KEEP: 8 × 5 because that helps us solve for your given equation
NEW EQUATION: x ≥ 8 × 5
8 × 5 = 40
Answer: x ≥ 40
It is a CLOSED circle SHADED to the RIGHT
What is the answer to this ?
Answer:
x - 1 and 5x - 7
Step-by-step explanation:
f(x) + g(x)
= 3x - 4 - 2x + 3 ← collect like terms
= x - 1
f(x) - g(x)
= 3x - 4 - (- 2x + 3) ← distribute parenthesis by - 1
= 3x - 4 + 2x - 3 ← collect like terms
= 5x - 7
Ann already knew 4 appetizer recipes before starting culinary school, and she will learn 3 new appetizer recipes during each week of school. Write an equation that shows the relationship between the number of weeks W and the number of appetizer recipes A.
Write your answer as an equation with a first, followed by an equals sign.
PLS SOMEONE ANSWER PLS PLS PLS! I WILL GIVE YO BRAINLIEST IF IT IS CORRECT!
Answer:
A = 3W + 4
Step-by-step explanation:
She learns 3 new recipes every week, which gives 3W
Then we add 4 because she already knew 4.

If frank have 395 marbles he putting in putting 22 in each bag how many marbles will he have in the bags that is not full
Answer:
21 bags are not full.
Step-by-step explanation:
Given that,
Total no. of marbles = 395
He is putting 22 marbles in each bags.
We need to find the number of marbles will he have in the bags that is not full. It can be calculated by dividing total no. of marbles and the no. of marbles in each bags.
[tex]x=\dfrac{395}{22}\\\\=17.95\\\\\text{or}\\\\=17\dfrac{21}{22}[/tex]
So, it means 17 bags are full but 21 bags are not full.
help me plz i’ll give u extra points

Find the coordinates of triangle ABC A(2,1) B(3,0) C(1,-2) after a dilation with a scale factor of 3
Answer:
Remember the key word”factor” which means to multiply. Multiple all those numbers by 3!
Step-by-step explanation:I’m going to do 2 of them and you can do the last one (2,1)x3= the dilation (6,3). (3,0)x 3 gives the dilation (9,0). (1,-2)x3 gives the dilation of (3,-6). See it’s very easy.

The speed of light is about 300,000 kilometers per second. The Sun is about 93 million miles from Earth. How many minutes does it take for the sunlight to reach Earth? Round to the nearest tenth if necessary.
Answer: 8.3 minutes
Step-by-step explanation:
1 mile is to 1.60934km so 93 million miles is:
= 93 * 1.609
= 149,637,000 km
Travelling at 300,000 km per second, the number of seconds it takes is:
= 149,637,000/300,000
= 498.79 secs
In minutes this is:
= 498.79/60
= 8.3 minutes

Write in slope-intercept form an equation of the line that passes through the points (−4, 2) and (6,−3).
Answer:
y = -0.5xStep-by-step explanation:
[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(−4, 2) ⇒ x₁ = −4, y₁ = 2
(6,−3) ⇒ x₂ = 6, y₂ = −3
So the slope:
[tex]\bold{m=\dfrac{-3-2}{6+4}=\dfrac{-5}{10}=-0.5}[/tex]
The point-slope form of the equation of the line passing through point (x₀,y₀) and with slope m is: y - y₀ = m(x - x₀)
m = -0.5
(−4, 2) ⇒ x₀ = −4, y₀ = 2
Therefore:
y - 2 = -0.5(x - (-4))
y - 2 = -0.5x - 2 {add 2 to both sides}
y = -0.5x ← the slope-intercept form of the equation (b=0)
From the expressions below, select the one that results in a negative difference.
uhm..
