Answer:

49 +80= 129

180 - 129= 51

Opposite are equal.

Extend line of QR - so, the x shape made can be used to calculate what x is.

51 + 51 = 102

Reflex angles adds to 360

360-102= 258 of the other opposite angles left.

258/2 = 129 since opposite angles are equal.

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. Each

Ostrovityanka [42]

Answer:

There were 7 small boxes and 14 large boxes shipped.

Step-by-step explanation:

This problem may be solved by a system of equations:

I am going to say that:

x is the number of small boxes used

y is the number of large boxes used

There were twice as many large boxes shipped as small boxes shipped

This means that $y = 2x$

Each small box of paper weighs 45 pounds and each large box of paper weighs 80 pounds. The total weight of all boxes was 1435 pounds.

This means that $45x + 80y = 1435$

So we have to solve the following system:

$y = 2x$

$45x + 80y = 1435$

$45x + 80(2x) = 1435$

$205x = 1435$

$x = \frac{1435}{205}$

$x = 7$

$y = 2x = 2(7) = 14$

There were 7 small boxes and 14 large boxes shipped.
