Answer:

subtracting 7 from 12

Step-by-step explanation:

That would be most efficient. Subtracting seven from twelve will quickly give you your value of x without moving the x itself. And there's no negatives

Answer:

Add -7 to both sides because that will result in an equivalent

equation with x alone on one side

You want to purchase a house in 6 years. the estimated cost is $160,000.00 and you want to make a 20% down payment. How much do
Dmitriy789 [7]
20% of 160,000 is 3,200. Divide that by 72 months you get $44.44 with a never ending stream of 4s. So you can pay $44.44 each month for six years and be 32 cents short, or you can pay $44.45 each month for six years and have 40 cents leftover. I wasn't sure which answer you were looking for so I gave you both. Hope that helps! :)

Solve for b A= \frac{a+b}{2}
lina2011 [118]
A = (a+b)/2
2*A = 2*(a+b)/2 ... multiply both sides by 2
2A = a+b
2A-a = a+b-a ... subtract 'a' from both sides to isolate b
2A-a = b
b = 2A-a

Answer: b = 2A-a

Answer:

The volume of this cylinder is 9184.5 cubic feet.

Step-by-step explanation:

The area of a circle is \pi r^2 and the volume of a cylinder with that base is just that area times the height:

V=\pi r^2\times h

Here, we're given the diameter, but we need the radius. The radius of a circle is just half of the diameter:

r=30\times0.5=15

Next, you can use that radius to calculate the area of the base:

A=3.14\times15^2\\A=3.14\times225\\A=706.5

Finally, multiply that by the height to find the volume of the cylinder:

V=706.5\times13\\V=9184.5

The volume of this cylinder is 9184.5 cubic feet.
