Answer:
<u>x=90</u>
Step-by-step explanation:
<em />
<em>Let's solve your equation step-by-step.</em>
x/9−5=5
<em>Step 1: Simplify both sides of the equation.</em>
x/9−5=5
1/9x+−5=5
1/9x−5=5
<em>Step 2: Add 5 to both sides.</em>
1/9x−5+5=5+5
1/9x=10
<em>Step 3: Multiply both sides by 9.</em>
9*(1/9x)=(9)*(10)
x=90
Answer:
<u>x=90</u>
P = 2(L + W)
P = 22
L = 2W - 4
22 = 2(2W - 4 + W)
22 = 2(3W - 4)
22 = 6W - 8
22 + 8 = 6W
30 = 6W
30/6 = W
5 = W.....width is 5 cm
L = 2W - 4
L = 2(5) - 4
L = 10 - 4
L = 6....length is 6 cm
Answer:
The total cost will be the same for both companies after 20 miles.
Step-by-step explanation:
First, I wrote the equations:
Laguna's Truck Rentals: 2x + 20
Salvatori's truck rentals: 3x
To find when the total cost for both companies will be the same, I kept substituting numbers for the variable until it worked. So, the total cost for both companies will be the same after 20 miles. Hope this helped!
Answer:
$98.10
Step-by-step explanation:
150 decrease 40% =
150 × (1 - 40%) = 150 × (1 - 0.4) = 90
90 increase 9% =
90 × (1 + 9%) = 90 × (1 + 0.09) = 98.1
