According to PEMDAS, the answer should 9.6
You would do 12-2, then multiply 10 x 0.9 which equals 9, then add 0.6 to 9 which equals to 9.6

All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Set Up Equation

29° + (4x + 9)° + (x + 17)° = 180°

Step 2: Solve for x

Combine like terms: 5x + 55 = 180
Isolate x term: 5x = 125
Isolate x: x = 25

The van traveled 120 miles in 7 hours. How long would it take to travel 1400 miles at the same speed? (A) 5/3 hrs (B) 81 2/3 hrs

trapecia [35]

Answer:

$81\frac{2}{3}$ hours

Step-by-step explanation:

Hi there!

1) Create a proportion

The van traveled 120 miles in 7 hours
The van travels 1400 miles in x hours

$\frac{7h}{120mi}=\frac{x}{1400 mi}$

$\frac{7}{120}=\frac{x}{1400}$

2) Solve for x

$\frac{7}{120}=\frac{x}{1400}$

Multiply both sides by 1400

$\frac{7}{120}*1400=\frac{x}{1400}*1400$

$\frac{245}{3} =x$

$81\frac{2}{3} =x$

Therefore, it would take the van $81\frac{2}{3}$ hours to travel 1400 miles at the same speed.

I hope this helps!

What is the slope of the line?

Anestetic [448]

Answer:

$m=\frac{-3}{2}$

Step-by-step explanation:

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Simply plug in 2 coordinates into the slope formula to find slope m:

$m=\frac{-1-2}{2-0}$

$m=\frac{-3}{2}$
