Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.
The answer is B. 60 cubic inches
5 x 6 x 2 = 60
Answer:
y=6
Step-by-step explanation:
y=kx
3=9k
k=3/9
k=1/3
y=kx
y=1/3 × 18
y=6
Answer:
r=−1/5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(r−10)=−51
(5)(r)+(5)(−10)=−51(Distribute)
5r+−50=−51
5r−50=−51
Step 2: Add 50 to both sides.
5r−50+50=−51+50
5r=−1Step 3: Divide both sides by 5.
5r/5=−1/5
r=−1/5
<span>well first off, you take 1350/9=150
then you add it all together 1350+150=1500
then your full answer would be $15 was the original price
