Answer:
x= 0
Step-by-step explanation:
Let's first simplify the equation to make the PEMDAS process easier.
8x-10=3x-10+7x
8x-10=10x-10
Now lets start the subtracting and dividing process.
8x=10x
0=2x
0=x
Answer:
a) 72
b) $259.2
Step-by-step explanation:
A- The bus travels 40 miles on 8 gallons of gasoline. The bus is traveling 360 miles in total.
360/40= 9
9*8= 72
B- $3.60 per gallon and 72 gallons in total.
3.60*72=259.2
$259.2
The problem above uses the concept of ratio and proportion. The ratio between the cost and amount of the organic milk should always be equal. The proportion between two cases is shown below,
($2.52 / 0.5 gallon) = (x / 4 gallons)
Solving for x gives x = 20.16. Therefore, 4 gallons of organic milk costs $20.16.
4(x+2)+2=14
4x+8+2=14
4x+10=14
Subtract 10 from both sides
4x=4
Divide by 4 on both sides
x=1
If the radius is tripped, the volume will increase by 3^3 = 27 times.
Answer: 27 times
