Answer:
B and D
Step-by-step explanation:
For there to be an infinite number of solutions, the quantity on the left side of the equation must be the same as on the right.
First, distribute the equation to get
6x + 18 = 3xh + 9h
If h = 2, the equation on the right would also be 6x + 18 which would yield the same equation and hence an infinite number of solutions
So the answer is h = 2
310 - 220 = 90
90/310 = x/100 (cross multiplication)
9000 = 310x
9000/310 = x
x = around 29%
Ummm...i think it is 265 because i did it the easy way i added
Step-by-step explanation:
The coefficients are 4, 5 and 7
There is no constant
The second one is right
