Answer: The answer to this question is t=9
Step-by-step explanation: This is the linear equation, to solve it we have to simplify the like terms.
-t= 9(t-10)
-t=9t-90
-10t=-90
t= 9
On the right hand side multiply through out by 9 and move 9t to the other side it will change side.
Then divide both sides by -10
Answer:
Multiply. To find the area of a shape, you multiply. Conversely, you add to find the perimeter of a shape.
Answer:
y = -6
Step-by-step explanation:
y = mx + b
-6 = -5(0) + b
b = -6
They equal to 180 because they are supplementary angles
Answer:
r=60°
Step-by-step explanation:
Both of the angles together make up 90°. we know this because of the red little box denoting 90°.
If one of the angles is 30°, to find the other one, simply subtract 30 from 90.
90-30=60
r=60°
