Answer:
The answer is below
Step-by-step explanation:
The question is not complete. The complete question is:
The 12 foot long bed of a dump truck loaded with debris must rise an angle of 30 degrees before the debris will spill out. Approximately how high must the front of the bed rise for the debris to spill out.
Solution:
Let x be the height of the front of the bed rise needed to be raised for the debris to spill out. We can find x using trigonometric identities. That is:
sin θ = opposite / hypotenuse
Using trigonometric identities, we can get that:
sin(30) = x / 12
This gives:
0.5 = x / 12
Cross multiplying the terms to get:
x = 12 * 0.5
x = 6 ft
Therefore the front of the bed rise must be raised 6 ft for the debris to spill out.
Let x = the unknown number
five more than a number = twice the number
x + 5 = 2x
5 = 2x - x
5 = x
( Balance method is used to solve )
substitution
x + 5 = 2x
5 + 5 = 2 x 5
10 = 10
answer : the unknown number is 5

Answer:
16 crayons in the last box
Step-by-step explanation:
when you divide 832 by 24, you get 34.some large decimal number. You now know that it must be less than that to get a whole number. So you can do 24 x 34 and get 816. you then have 16 left over and that will go into the last box.
