Answer:

35 smaller trucks.

Step-by-step explanation:

Given:

i) The larger truck with a 2.5-ton payload, and smaller trucks with 1.5-ton payload.

ii)  To unload a freight train 21 larger trucks are needed .

Total load of the freight train = 21 times 2.5 tons

= 21  × 2.5

= 52.5 tons

To find the number of small trucks needed, we need to divide 52.5 by 1.5

= 52.5 ÷ 1.5

= 35 small trucks needed.

So, to unload the freight, we need 35 smaller trucks.

fomenos

Answer:

three halves

Step-by-step explanation:

1/2 * 3 = 3/2 = 1 1/2 = 1.5

Multiple: 1/2 * 3 = 1 · 3/2 · 1 = 3/2

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(3, 2) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - one half multiplied by three = three halfs.

4d^-3 multiplyed by d^18
Verdich [7]
4*d^(-3)*d^18 = 4*d^(18-3) = 4*d^(15).  The trick here is to combine the exponents.

Another way to write this problem would be:

4*d^18
---------- .  Here d^18 divided by d^3 results in d^15, so again the final 
  d^3         answer is 4*d^15.

One increased by 7 times a number is the same as 5 times the number plus 25
sammy [17]

Answer:

12

Step-by-step explanation:

Let the number = x

7x + 1 = 5x + 25                 Subtract 5x from both sides.

7x - 5x + 1 = 5x - 5x + 25   Combine

2x + 1 = 25                          Subtract 1 from both sides.

2x + 1 - 1 = 25-1                   Combine

2x = 24                               Divide by 2

2x/2 = 24/2

x = 12
