Answer:
x = 19
Step-by-step explanation:
3(x - 9) = 30
Divide both sides by 3 to isolate the binomial.
x - 9 = 10
Add 9 to both sides to isolate x.
x = 19
Check your answer by plugging x = 19 back into the equation.
3(x - 9) = 30
3(19 - 9) = 30
Subtract.
3(10) = 30
Multiply.
30 = 30
Your answer is correct.

Answer:
r=201
d = 77 1/2
Step-by-step explanation:
6) First multiply left and right by 16, to get rid of the fraction:
r - 25 = 11*16
Now add 25 left and right:
r = 11*16 + 25 = 201
7) Add 5 left and right
2/5 d = 31
multiply by 5/2
d = 31 * 5/2 = 77 1/2
Answer:
840
Step-by-step explanation:
(−30)(−7) − (210)(−3)
=210 − (210)(−3)
=210 − (−630)
