Answer: B

Step-by-step explanation: The answer would be B because both the 8x and 22x are both negative so once you add those two together you would get -30x so that cancels out A and C. SO now you move onto 23 and 9 well both of those are positive so you would add those together and get 32 so that cancels out D and only answer left is B

Por que:

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 55 p

Natali [406]

Answer:

Large boxes = 40 lbs.

Small boxes = 15 lbs.

Step-by-step explanation:

L = Large Box

S = Small Box

I started by making the equations, L + S = 55 and 60L + 50S = 3150. I made the first equation L = 55 - S and substituted that in for L in 60L + 50S =3150. After finding S, I plugged that back into L + S = 55 and got the answers.

Answer:

Step-by-step explanation:

50, 80 and 6x - 4 are interior angles of a triangle.

Note : -

Sum of interior angles in a triangle is 180.

6x - 4 + 50 + 80 = 180

6x = 180 - 50 - 80 + 4

= 180 - 130 + 4

= 50 + 4

6x = 54

x = 54 / 6

x = 9
