Mathematics
2 answers:
choli [55]3 years ago

Answer:

see below

Step-by-step explanation:

a. -11r ≥ 220

Divide both sides by -11 to isolate r.

r ≥ -20

b.

-8 ≤ -7 + (x/10)

Add 7 to both sides.

-1 ≤ x/10

Multiply both sides by 10 to cancel out the denominator of x.

-10 ≤ x

c. -1 - 6(5q - 2) ≥ -139

Distribute the -6 across the parentheses.

-1 - 30q + 12 ≥ -139

Combine like terms on the left side.

-30q + 11 ≥ -139

Subtract 11 from both sides.

-30q ≥ -150

Divide both sides by -30 to isolate q.

q ≥ 5

Hope this helps!

-11r>=220

divide both sides by -11
since both sides are divided, flip the sign

r<=-20
r is less than or equal to negative twenty

i’m not sure how to complete the other questions, but i hoped #1 helped :)
