You plug in the numbers. For example, for the first one you plug in 7 to 4.9=0.7m.
You replace the m with 7 then solve. 4.9=0.7(7)
4.9=4.9
which will make the answer infinite solutions since it is a true statement.

Mademuasel [1]

Answer:

r = 15

Step-by-step explanation:

10(8r + 23) = 1430

Divide both sides by 10.

8r + 23 = 143

Subtract 23 from both sides.

8r = 120

Divide both sides by 8.

r = 15
