4(a-2)=3(a+4)
4a-8=3a+12
a=20
Answer:
The per hour rate is 0.5 inches per hour
Step-by-step explanation:
Here, we want to calculate the rate at which the level of the water increased
Mathematically, we can get this by dividing the amount of increment by the time it took
That would be 3 inches divided by 6 hours
= 3/6 = 0.5 inches per hour
Answer:
2x + y = 20
Step-by-step explanation:
gradient = -2
x = 6, y = 8
y - 8 = -2(x - 6)
y - 8 = -2x + 12
2x + y = 12 + 8
2x + y = 20
Answer:
27.3
Step-by-step explanation:
−4y + 4y + 2 = 2
<span> −4y + 4y = 2 -2
0 = 0 .
Anytime you have this format of 0 = 0, just know there are infinitely many.
Any number as a value of y can satisfy the equation.
