Answer:
Part A, one solution
Part B, x=3
Step-by-step explanation:
divide both sides of the equation by 7 (5x-13=2)
move the constant to the right hand side and change its sign (5x=2+13)
add numbers (5x=15)
divide both sides of the equation by 5 (x=3)

.275 is 275/1000 in decimal form
Answer:
60% of 5 is 3
Step-by-step explanation:
I'm guessing you want to find what ? is.
Okay. The perimeter is the sum of all of the sides, right, so we can set up an equation. Since I'm too lazy to have to hit the caps button thingy each time, the ? mark will just be represented by a letter, y.
y+x+x+3x+1=6x+2
Simplify the left side of that.
5x+1+y=6x+2
We want to find what y (or ?) is, right? So we can just solve for y in the equation.
y=(6x+2)-(5x+1)=x+1
The ? stands for x+1.
Hope this helps!
