Answer:
x=15
y=18
Step-by-step explanation:
then x+y=33
and 2x+5y=120
then x=33–y
since 2x+5y=120
then 2(33–y)+5y=120
then 66–2y+5y=120
then 66+3y=120
then 3y=120–66
then 3y=54
then y=54/3
then y=18
then x=33–18=15
47mph and 32 kph
The ratio is 1.6kph for every 1mph so for the first one you divide by 1.6 and the second you multiply
4x + 3 < 3x + 6
4x - 3x < 6 - 3
x < 3
10*50,10*30,10*40 are all the multples
