Answer:
x=0.369231
Step-by-step explanation:
0.9(5x+4)=5.7(2.5x)
Step 1: Simplify both sides of the equation.
0.9(5x+4)=5.7(2.5x)
(0.9)(5x)+(0.9)(4)=5.7(2.5x)(Distribute)
4.5x+3.6=14.25x
Step 2: Subtract 14.25x from both sides.
4.5x+3.6−14.25x=14.25x−14.25x
−9.75x+3.6=0
Step 3: Subtract 3.6 from both sides.
−9.75x+3.6−3.6=0−3.6
−9.75x=−3.6
Step 4: Divide both sides by -9.75.
−9.75x/ −9.75 = −3.6/ −9.75
x=0.369231
3. C 67.5 mi
4. A 65mi
5. B $270
Step-by-step explanation:
$ 900 is the answer. as i shown in the attachment
R + t = 42
r = 25
Plug in 25 for r
(25) + t = 42
Isolate the t by subtracting 25 from both sides
t + 25 (-25) = 42 (-25)
t = 42 -25
t = 17
Hope this helps
Answer:
m is 55.
Step-by-step explanation:
Multiply both sides by 5 to isolate the variable m
11=m/5
11*5=m
55=m
