If $26 represents the cost of the 5 used CDs, than your formula would be "26+4x" ,x being the amount of extra CDs you purchase.
The number CDs minus 5 is our x value, because the first 5 are the used CDs bundled into the $26 group.
26+4(6-5)
26+4(1)
26+4
30
6 CDs would cost $30
Answer:
blue : red
7 : 12
Step-by-step explanation:
blue : red
28 48
Divide each by 4
28/4 48/4
7 12
blue : red
7 : 12
$9 + $7 + $5 = $21 so $18 - $21 = account balance = -$3
The answer is 1.6
How I figured it out:
I divided 8 by 5, which gave me 1.6
To make sure this was right, I multiplied 1.6 by 5, which gave me an answer of 8 or other known as 8 inches.
In conclusion, the number of inces per hour is 1.6
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
4(x−7)=2(x+3)
Simplify both sides of the equation.
4(x−7)=2(x+3)
4x+−28=2x+6
4x−28=2x+6
Subtract 2x from both sides.
4x−28−2x=2x+6−2x
x−28=6
Add 28 to both sides.
2x−28+28=6+28
2x=34
Divide both sides by 2.
2x/2 = 34/2
x = 17
