Answer:
x = -12
Step-by-step explanation:
Remember that ax + bx = (a+b)x
-10x + 9x = 12
Add -10x and 9x together
(-10 + 9)x = 12
-x = 12 (-1x is written as -x, just as 1x is written as x)
÷ -1 both sides
x = -12
I hope this helps. Happy studying. :)
Only the triangular prism will hold 30 gallons of water.
First, we need to find the volume of the prism.
It is: V = (24 x 25)/2 x 28 = 8400 in^3
Since there are 231 cubic inches in a gallon, so there are 36.4 gallons in the tank. 8400 / 231 = 36.4
The pyramid would only have one-third of the volume.
Answer:6
Step-by-step explanation:Take the derivative of the numerator and denominator, then evaluate the limit.
We need to create two expressions, then equate them in order to find the numbers of hours.
Let X = Number of hours
Let 1200+18x = Company A (Flat Fee + Hourly Rate*Hours)
Let 900+23x = Company B
After 60 hours, the prices will be the same
Set it up as a propotion and cross multiply. 10/23=15/x answer is 34.5
