There are 150 pencil crayons altogether.

Step-by-step explanation:

Given that pencil crayons are stored in boxes of 10, and there are 4 boxes of red, 3 boxes of blue, 5 boxes of green and 3 boxes of orange in the storage room, to determine how many pencil crayons are there altogether must be done the following calculation:

10 x 4 + 10 x 3 + 10 x 5 + 10 x 3 = X

40 + 30 + 50 + 30 = X

70 + 80 = X

150 = X

Therefore, there are 150 pencil crayons altogether.

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
