57s

Step-by-step explanation:

100s- 3s- 40s so what you want to do first is subtract 3s from 100s which gives you 97s then, you subtract 40s from 97s that gives you the 57s.

courtesan no naked yes

hope this ^_^

do you see a nakes

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
