(2y + 50)" (7x - 248)<br> (5y - 17) (x +44)°<br> Find the value of x and y.
Sveta_85 [38]

Answer:

x = 48

y = 21

Step-by-step explanation:

To find the value of x and y, using the definition of supplementary angles, create an equation to find x and y as follows:

Finding y:-

(2y + 50) + (5y - 17) = 180 (supplementary angles definition)

Solve for y

2y + 50 + 5y - 17 = 180

Collect like terms

2y + 5y + 50 - 17 = 180

7y + 33 = 180

7y + 33 - 33 = 180 - 33

7y = 147

\frac{7y}{7} = \frac{147}{7}

y = 21

Finding x:-

(7x - 248) + (x + 44) = 180 (supplementary angles definition)

Solve for x

7x - 248 + x + 44 = 180

Combine like terms

8x - 204 = 180

8x - 204 + 204 = 180 + 204

8x = 384

\frac{8x}{8} = \frac{384}{8}

x = 48

Isolate x; you must get all the constants on one side of the equation and the variables on the other side. Use subtraction/addition to do this. Reply to me once you've done that if you still need help.

Workers are loading boxes onto a truck. So far, they have loaded 48 boxes onto the truck
Talja [164]

Answer:

1,200 total on truck

Step-by-step explanation:

48=4% loaded on a truck and they have 96% left to load

So set up a proportion and it should look like this

48 over x = 4 over 100

48/x=4/100

Do cross multiplication 100×48= 4,800÷ 4 = 1,200 total on truck

=1,200 total on truck

Hope this helps, have a nice day! :D
