Answer:
$20.52
Step-by-step explanation:
19x0.08 (that's 8% or 8/100) = $1.52
$19+$1.52= $20.52 :)
Step-by-step explanation:
1*-2=-2, -2*-2=4, -2*4=-8, -8*-32=256
Hey there! :)
Answer:
m = 4.25, or 17/4.
Step-by-step explanation:
Given the proportion:

Cross multiply:
8(m - 3) = 5 · 2
Distribute the 8:
8m - 8(3) = 10
8m - 24 = 10
Add 24 to both sides:
8m = 34
Divide both sides by 8:
8m/8 = 34/8
m = 4.25, or 17/4.
