Answer:
x=3, y=-1
Step-by-step explanation:
We are already given an equation solved for x, making substitution much easier. We know x=4y+7, meaning we can put 4y+7 whenever we see x in the second equation
2x-6y=12
We substitute 4y+7 in place of x
2(4y+7)-6y=12
Now we only have one variable to work on, distribute the 2
8y+14-6y=12
Combine similar terms, 8y-6y=2y
2y+14=12
Subtract 14 from both sides
2y=-2
y=-1
Now we plug in -1 for y in the first equation to find x
x=4(-1)+7
x=-4+7
x=3
Equation = 14,443x + 98,232
February till April = 3 months
14,443(3) + 98232 = $141,561
Answer:
3x12 theres 3 cirs and 6÷4 so 3x12
Answer:
2.5 ft
Step-by-step explanation:
A rectangular prism's volume is given by it's base area multiplied by it's height:
In this problem, we are given the volume and the base area, so we need to solve for h:
The units are feet, so the answer is 2.5 ft.
2^7 * (3³-1) = 128*26=3328. better check the problem again
