Mathematics
1 answer:
expeople1 [14]3 years ago
7 0

Answer:

Step-by-step explanation:

9(c+7)=27

9c+63=27  subtract 63 from both sides

9c=  -36  divide by 9

c= -4

3(2r-8)+4r=76 foil

6r-24+4r=76 combine like terms

10r-24=76 add 24 to both sides

10r+100  divide by 10

r= 10

Which represents the solution set of 5(x+5)&lt;85?
Nostrana [21]

The answer is: x<12

Steps by steps

5(x+5)<85

Divide each term by 5 and simplify.

5(x+5)÷5<85÷5

Reduce the expression by cancelling the common factors.

x+5<85÷5

Divide 85 by 5.

x+5<17

Move all terms NOT containing "x" to the right side of the inequality.

Subtract 5 from both sides of the inequality.

x<-5+17

Add -5 and 17.

=x<12
