Answer:
Linear equation : y = 2.50h + 5
Step-by-step explanation:
Given that:
Fee for renting roller blades = $5
Per hour charges = $2.50
Let,
h be the number of hours roller blades were rented
y be the total amount
Total amount = Per hour charges * Number of hours + Flat fee
y = 2.50h + 5
Hence,
Linear equation : y = 2.50h + 5
Answer:
x = -7
Step-by-step explanation:
4 - 2(x - 3) = 24
Distribute
4 -2x +6 = 24
Combine like terms
10 -2x = 24
Subtract 10 from each side
10-2x-10 = 24-10
-2x = 14
Divide by -2
-2x/-2 = 14/-2
x = -7
On the left side of the equation, we have 3x or 3 * x. But in algebra, we usually just do 3x.
We need to find a value for x that when multiplied by -3 equals to -216.
We can find the value for x by dividing both sides by the coefficient of 3x. Which is 3.
3x / 3 = -216 / 3
x = -72
So, x is equal to -72.
