Solve the equation for x. Check the solution.
2. -5(x + 3) = 20
Answer:
x = -7
Step-by-step explanation:
-5( x + 3 ) = 20
Distributive property ( multiply whatever is in the parenthesis by -5)
-5 * x + -5 * 3 = 20
-5x - 15 = 20
Add 15 on both sides
-5x - 15 + 15 = 20 + 15
-5x = 35
Divide by -5 on both sides to isolate the variable
-5x/-5 = 35/-5
x = -7
Check...
Substitute the "x" with -7 since we already got that as our solution
-5( x + 3 ) = 20
-5( -7 + 3 ) = 20
Distributive property
-5 * -7 + -5 * 3 = 20
35 - 15 = 20
20 = 20 CORRECT

Mark is making a scale model of his favorite truck. The actual truck is 12 feet long and 5 feet wide. He wants the model to be 30 inches in length. Using a proportion, find the model truck’s width.
Answer:
the model trucks width would be 12.5 inches.
Step-by-step explanation:
set up a proportion.
12/5=30/?
cross multiply.(this makes sense when the fraction is written out correctly)
5x30=150
now divide this by your remaining number in the fraction.
150/12=12.5

I don't wanna fail math aaaa
Answer:
C
Step-by-step explanation:
Follow Pythagorean Theorem. a^2 + b^2 = c^2
We know b and c:

a^2 + 144 = 169
a^2 = 25
a = √25
a = 5
The answer is C because we know side a = 5

For question 1 the answer is b)
- Congruent angles have the same angle measure, and in a transversal, angles that are opposite around an intersection are congruent. For example ∠ 1 and ∠ 3 are congruent. Because the 2 lines are parallel (and intersected by the same line) the corresponding angles on the other intersection are also congruent. For example if ∠ 1 and ∠ 3 are congruent, then ∠ 5 and ∠ 7 are also congruent.
For question 2 the answer is b) 45°
- ∠ 3 and ∠ 4 are supplementary, meaning they equal 180° together. To solve you just need to subtract, 180° - 135° = 45°
For question 3 the answer is d) 145°
- This combines the previous 2 concepts. ∠ 1 and ∠ 5 are congruent (equal), ∠ 1 and ∠ 2 are supplementary. If ∠ 1 is 180° - 35° = 145°, and ∠ 1 and ∠ 5 are congruent, then ∠ 5 is also 145°.
For question 4 the answer is a) ∠ 1, ∠ 4, ∠ 5, and ∠ 8
- First, ∠ 4 is supplementary because it falls along the same straight line (line m), similarly ∠ 1 is supplementary because it falls along a different straight line (the transversal). Because lines n and m are parallel and both intersected by the transversal, the corresponding angles, ∠ 5 and ∠ 8, are also supplementary.
For question 5, the answer is b) m∠ 3 = 70°
- ∠ 7 is supplementary to the 110° angle, so m∠ 7 = 180°-110° = 70°, ∠ 7 and ∠ 3 are congruent, so m∠ 3 also equals 70°
