Answer:
<h2><u>
j = 38</u></h2>
Explanation:
ʲ⁄₋₂ + 7 = -12
Subtract 7 From Both Sides
ʲ⁄₋₂ + 7 - 7 = -12 - 7
Simplify
ʲ⁄₋₂ = -19
Multiply Both Sides By -2
(-2) ʲ⁄₋₂ = -19 (-2)
<h2><u>j = 38</u></h2>
Answer:
<h2>5 + 3w + 3 - w = 2w + 8</h2>
Step-by-step explanation:
![5+3w+3-w\qquad\text{combine like terms}\\\\=(3w-w)+(5+3)\\\\=2w+8](https://tex.z-dn.net/?f=5%2B3w%2B3-w%5Cqquad%5Ctext%7Bcombine%20like%20terms%7D%5C%5C%5C%5C%3D%283w-w%29%2B%285%2B3%29%5C%5C%5C%5C%3D2w%2B8)
Your answer is the first option, 8.0. You can find this by using the sine rules for sides, so:
10/sin(90) = x/sin(53)
× sin(53)
7.98 = x
And 7.98 rounded to the nearest tenth is 8.0.
I hope this helps!
