Step-by-step explanation:
draw it on a number line to check
Answer:
15 inches
Step-by-step explanation:
Volume = lwh
150 = (5)w(2)
150 = 10w
w = 15
Answer:
c
Step-by-step explanation:
y-6<0,y<6
all graphs satisfy it
y<x+4
when x=0,y<4
c satisfies it.
y+6>-3x
when x=0,y>-6
c satisfies it.
a b
c d
1. Rewrite the system:
x+12y=68 (i)
x=8y-12 (ii)
2. Let's substitute the equation (ii) into the equation (i):
x+12y=68
(8y-12)+12y=68
3. Then, you have:
8y-12+12y=68
4. When you clear "y", you have:
20y-12=68
20y=68+12
20y=80
y=80/20
y=4
5. You already have the value of "y". Now, you must substitute this value into the equation (ii):
x=8y-12
x=8(4)-12
x=32-12
x=20
6. Therefore, the result is:
x=20
y=4
We have to find the area of each wall and then multiply it by the number of gallons.
So the formula of the two walls are 2(26*9), which is 2(234) then simplified into 468.
Afterwards we have to multiply 468 * 250 and get 58500 sq ft
Ans:58500 sq ft
