Answer:
personally i think x=6
Step-by-step explanation:
but heres how i got it cross multiiply 7.5/4 and x/3.2
witch makes 24=4x then divide by 4 and you get x=6
so.... yeah i think x=6
if brainiest is earned its greatly appreciated
Answer:
10 =x
Step-by-step explanation:
f(x) = x-7
Let f(x) = 3
3 = x-7
Add 7 to each side
3+7 = x-7+7
10 =x
3 + 4x - 3x = 4 Given
3 + (4x - 3x) = 4
3 + x = 4 Combine like terms
3 - 3 + x = 4 - 3
x = 1 Subtraction Property of Equality
Answer:
12x=10(25+x)
Step-by-step explanation:
Jim's rate=x
Pete's rate=y
Jim and Pete lays the same number of tiles.
So we have,
12x=10y
Pete's can lay 25 more tiles than Jim per hour
We have
y=25+x
Substitute y=25+x into 12x=10y
12x=10y
12x=10(25+x)
12x=250+10x
12x-10x=250
2x=250
x=250/2
=125
x=125
12x=10(25+x) is the equation used to find the rate that Jim can lay tiles
Therefore,DE=4y-8=4*6-8=16
And ,BE=y+10=6+10=16
=>BD=DE+EB=16+16=32
Hope This helps u...!!
