Simply cross multiply:
18*m = 6*15
18m = 90
m = 5
Answer:
10y - 3
Step-by-step explanation:
Write "10y minus 3" symbolically: 10y - 3
8-4/5f=-14-2f
Multiply both sides by 5
40-4f=-70-10f
Move variable to left and change signs
-4f+10f=-70-40
Combine like terms
6x=-70-40
6f=-110
Divide both sides by 6
F=-55/3
Step-by-step explanation:
you subtract -4 by 7.
then you hav 5x=7
you divide 5x by 5 and seven by five so your x= that answer
then you put that number into the x in the second equtaion
then you subtract that number after multiplying the 6 by the number x equals
then you divide 2y by 2 and 22 by 2 and thats your y value
Answer:
About 6 days.
Step-by-step explanation:
