4x+4=-3+2x+15
Step 1: combine like terms
4x-2x=15-3-4
2x=8
Step 2: divide by 2 on both sides
x=4
Answer:
12) y=25x
13) 14 gallons
Step-by-step explanation:
m= (y2-y1)/(x2-x1)
m= (75-50)/(3-2)
m=25/1=25
y-y1=m(x-x1)
y-75=25(x-3)
y-75=25x-75
y=25x
------------------------------------
350=25x
x=350/25
x=14
There are 2000 pounds in a ton
So just multiply
2000*5= 10000
So there are 10000 pounds in 5 tons
Multiply 35 by your chosen denominator. Example, 35 can be expressed as 70/2 or 105/3
