Answer:
<u>The answer is x = -2</u>
Step-by-step explanation:
Let's solve for x the equation -3(x+5)=-9, this way:
-3 (x + 5) = - 9
-3x - 15 = -9 (Solving the parenthesis)
-3x = -9 + 15 (Adding 15 at both sides)
-3x = 6
x = 6/-3 (Dividing by -3 at both sides)
x = -2
<u>The answer is x = -2</u>
Answer:
h = 30°
Step-by-step explanation:
All angles in a triangle add up to 180°, so:
60° + 90° + h° = 180°
Solving for <em>h</em>, we should get 30 as our answer.
This is a case where we have to multiply fractions.
4/5 × 2/3 = 8/15
Hope this helps!
