Answer:
You were close; you don’t have to add 3x to the right side though.
We’re given 2y= -3x + 6
Step one: divide both sides by 2
y= (-3/2)x + 3
Answer:
P=40
a + b + x = P
a = 3x
b = x + 5
substitute for b & y
3x + (x+5) + x = 40
Step-by-step explanation:
longest section 1 = a
mid length section 2 = b
shortest section 3 = x
P=40
a + b + x = P
a = 3x
b = x + 5
substitute for b & y
3x + (x+5) + x = 40
5x + 5 = 40
5x = 35
x = 7
b = 12
a = 21
14/4
Multiply the denominator and the whole number - 4*3=12
Add the numerator - 12+2=14
Put the answer over the denominator 14/4
