Steps to solve:

-4(r + 3) = -42

~Distribute

(-4 * r) + (-4 * 3) = -42

~Simplify

-4r - 12 = -42

~Add 12 to both sides

-4r - 12 + 12 = -42 + 12

~Simplify

-4r = -30

~Divide -4 to both sides

-4r/-4 = -30/-4

~Simplify

r = 7.5

Best of Luck!

3. Find the angle complementary to the angle 80°25′. A. 180° B. 9°35′ C. 90° D. 99°35′
svetlana [45]
"Complementary" angles sum to 90°.

Since we are using minutes as well...

80°+d°+25'+m'=90°  subtract 80° from both sides

d°+25'+m'=10°  subtract 25' from both sides

d°+m'=9°+60'-25'

d°+m'=9°+35'

9°35'
