Length= 28
Width= 14
Work:
2(2x)+2(x)=84
4x+2x=84
6x=84
x=14
14x2=28 (length)
Answer:
110
Step-by-step explanation:
Let x = rate #1 and then 155-x=rate #2.
15x + 5(155-x) = 1225
15x - 5x + 775 - 1225
10x = 450
x = 45, second rate is 110
x is timed by .5 in the first one (A) which would make it the linear function.
The answer is x=2
show you step-by-step
step 1:simplify both sides of the equation.
(4)(x)+(4)(2)=6x+4
4x+8=6x+4
step 2:subtract 6x from both sides.
4x+8-6x=6x+4-6x
-2x+8=4
step 3: subtract 8 from both sides
-2x+8-8=4-8
-2x=-4
step 4: divide both sides by -2
-2x/-2= -4/-2
x=2
that helps you
