Answer:
Since x is an integer we conclude that there are 10 trucks needed to carry away 45 tones of debris.
Step-by-step explanation:
First we will find the volume of the dump truck:
V = 10*15*6.5
V = 975 ft^3
1 ton = 200 ft^3
45 tons = 45*200 ft^3
45 tons = 9,000 ft^3
Let x represent the number of trucks needed to carry away 45 tones of debris:
975*x = 9000

<em>Six (6)</em> different pizzas can be made with one vegetable and one meat.
They are:
1). broccoli, pepperoni

4). peppers, sausage
5). onions, pepperoni
6). onions, sausage
Estimate = 700 lbs
Real bear = 634 lbs
Difference = (700 - 634) = 66 lbs
The estimate is <em>66 pounds more</em> than the actual weight.
The estimate is 10.4% too high.
The actual bear weighs 9.4% less than the estimate.
Answer:
Your friend is correct.
Step-by-step explanation:
He is right because 70 is ten times greater then 7 and the question is if the 7 in the hundredths which equals 70, is 10 times greater than the 7 in the thousandths, which is equal to 7. (7 X 10 equals 70.) Hope this helps! :)
You can multiply both sides of the equation by 12 to remove the fractions.
12(35 - x/4) = 12(x/3)
420 - 12x/4 = 12x/3
420 - 3x = 4x
Add 3x to both sides:
420 = 7x
Divide 7 to both sides:
x = 60
