3x - 7y = -28
subtract 3x both sides
7y = -3x - 28
Divide both sides by 7
y = 3/7x + 4

A right rectangular prism has a length of 20.2 cm, a width of 9.1 cm and a height of 14.3 cm. What is the surface area of the ri
Alina [70]
To find this the first step we do is multiply the length by the height (20.2 x 14.3) to get 288.86.  Now there are 2 sides just the same so together it would be 577.72.  Next is width times height.  9.1 times 14.3 to get 130.13 then times that by 2 to get 260.26.  So far we have this 577.72 + 260.26 + (length times width).  20.2 times 9.1 is 183.82 then times that by 2 to get 367.64.  Now we add all of them to get 1205.62 cm^2.  The surface area of the right rectangular prism is 1,205.62 cm^2.  If this is wrong please let me know so I can research more on the subject.  Thanks :)

Can you solve this geometry problem?
Feliz [49]

Answer:

m<UTV = 100°

Step-by-step explanation:

360 = 140 + 120 + m

360 = 260 + m

360 - 260 = 260 - 260 + m

100 = m

----------------------------------------

360 = 140 + 120 + 100

360 = 260 + 100

360 = 360

What's 2 + 2 in a mathematical sense
Setler [38]

In a mathematical sense..

Not to make it too complicated, however, here's where we get on to the real mathematics.

There are infinite equations for 2 + 2. The gap between any number can be infinite if you keep giving it more numerical content. However, solving 2 + 2 can be very tricky.

1 + 1 + 1 + 1 = 4. Easy, right? Wrong. We can deduct from this equation that 1 + 1 = 2, so if we do 1 + 1 PLUS 1 + 1, (1 + 1 + 1 + 1 again), that equals four, because 1 + 1 is 2 and if we add another 1 to 2, 1 + 2, it equals 3, so 1 + 3 = 4. I'd like to remind you-- this works both ways, whether or not it's 3 + 1 or 1 + 3, it equals 4. If we carry the 1 from the three and put it in a separate number in an equation, said equation is now 1 + 1 + 2. It still equals 4, because 1 + 1 = 2 and if you take 2 and put it in 1 + 1's place, it's 2 + 2.

2 + 2 = 4.

(this was a joke answer, don't take anything said in this answer seriously.. OR you can if you want, because it's all true.. 2 + 2 = 4.)

Hope this helped!

- William.
