building in feet and inches?

Answer:

32 +( -17)=15

Step-by-step explanation:

He made an error in step 1. Specifically, he distributed incorrectly.

The 3(x+2) portion is not the same as 3x+2. We need to multiply that '3' by the 2 as well to get 3*2 = 6

In other words, 3(x+2) should turn into 3x+6

If you wanted, you can think of 3(x+2) as three copies of (x+2) added together like this:  (x+2)+(x+2)+(x+2) = (x+x+x)+(2+2+2) = 3x+6

Answer:

4.2

Step-by-step explanation:

for college, 1-1/2-1/5 = 3/10. Divided by 3 children, 3/10 /3 = 1/10

B. 400 = 1/10 of the total (from above), so 400 = x/10. x = 400*10 = 4000

Answer:

$2,500

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

(4^2 - 8 +2 * 10) / ( 3^2 - 5)

(P) E M D A S

Solve inside of perithesis first:

((4^2) - 8 +2 * 10) / ((3^2) - 5)

P (E) M D A S

4^2 = 16         , & 3^2= 9

Plug in:

(16 - 8 + 2 * 10) / (9 - 5)

P E (M) D A S

2*10= 20

Plug in:

(16 - 8 + 20) / (9 - 5)

P E M D (A S)

in order from left to right:

16-8=8, 8+20=(28)

&

9-5=(4)

Plug in:

28 / 4

P E M D A S

28/4= 7

Answer: 7

An l || m, m7 = 2x and m2 = x, then what is the measure of angle 2 is 30°.

To find the measure of angle 2, use the properties of parallel lines and transversals.

Given that line l is parallel to line m, and we have two angles formed by a transversal intersecting these lines, angles 2 and 7.

are given that m7 = 2x and m2 = -1.

Since lines l and m are parallel, alternate interior angles are congruent. Therefore, angle 2 and angle 7 are congruent.

m2 = m7 (alternate interior angles are congruent)

Since m7 = 2x,  substitute:

m2 = 2x

But, we are also given that m2 = -1, so set up an equation:

-1 = 2x

Now, solve for x:

x = -1/2

Now that have the value of x, find the measure of angle 2:

m2 = 2x

m2 = 2(-1/2)

m2 = -1

Therefore, the measure of angle 2 is -1 degree. However, it's worth noting that angles are typically measured as positive values, so the answer in this case would be 1 degree (considered as an acute angle). None of the multiple-choice options provided matches this answer exactly, but the closest one would be 30°.
