Let's look at the equation we have.
18x + 2x = 31
The first step would be to combine like terms. Ex: 18x and 2x
18x + 2x = 31
20x = 31
Now, to isolate the x, you would divide both sides by 20.
20x = 31
x = 1.55
x = 1.55
I hope this helps!
Answer:
He did 2 divide by 2.50 instead of 2.50 divide by 2 like x and y y=kx
Step-by-step explanation:
2.50 ➗2 = 1.25 per pound
1 lbs =1.25
W=3/4L
P=2L=2W
70=2L+2(3/4L)
70=2L+6L/4
70=2L+1.5L
70=3.5L
L=70/3.5
L=20 FT. ANS. FOR THE LENGTH.
W=4/4*20=15 ANS. FOR THE WIDTH
i think.
3+2.50=P or 5.50
this doesn't matter just trying to get 20 characters
Matt sold the most, figure out the percentages of each by diving the top number by the bottom number.
