60
7:3
7+3=10
60/10=6
6*7=42
6*3=18
42 cars
18 trucks
Y=mx+b now just re do them
First equation:
5(x+1)=20 —— distribute the 5 to the x and 1
5x+5=20 ——- subtract 5 from 20
5x=15 ———— divide by 5 from both sides
X=3 ————— answer
Second equation:
5x+1=20——— subtract 1 from 20
5x=19 ———— divide by 5 from both sides
X=19/5———— answer in fraction form
X=3.8————- answer in decimal form
Set the two values equal to each other with 18x-2=12x+2 and then plug it in to the equation and solve
Answer:
The answer is:
Option 4; (14+ 9) 4 is twice as much as(14 + 9) 2
Thanks
