You can sum like terms. Two terms can be summed if they are both constants (i.e. pure numbers) or if they involve the same powers of the same variable.

In this case, 3x and 13x can be summed because they both involve 'x' alone. The sum is

3x+13x = (3+13)x = 16x

As for the other two terms, you simply have to sum two numbers, as usual:

-9-6 = -15

So, the final answer is

16x-15

Elis [28]

Answer:

15 fezzes

Step-by-step explanation:

1. Okay, so first you want to convert the yards of felt to inches to make the math easier. There are 36 inches in a yard so multiply 3 3/4 × 36.

To do this you should convert the fraction to improper.

3 3/4 = 15/4

ok so now multiply to turn it into inches.

15/4 × 36 = 540/4

now just simplify

540/4 = 135

2. So now that you know that she has 135 inches of felt all you have to do is divide by the cost per fez, which is 9.

135/9 = 15

52<br> base six <br><br> Write the normal number
saveliy_v [14]

19770609664 is simple power of 52⁶ .

What is exponent and power?

  • A base number raised to an exponent is referred to as a power in mathematics, where base number is the factor that is multiplied by itself and exponent is the number of times the same base number is multiplied.
  • Exponents and powers are two techniques for simplification of extremely big or extremely small numbers.
  • As an illustration, we can write 3 x 3 x 3 x 3 as 34, where 4 is the exponent and 3 is the base, if we need to represent it simply.
  • It is claimed that the entire statement 34 has power.

= 52⁶

= 52 × 52 × 52 × 52  × 52 × 52

=  19770609664

A delivery company has 18 vehicles in its fleet.
Ilia_Sergeevich [38]

Answer: £1517.04

Step-by-step explanation:

The fuel expenses for the vans will be calculated as:

Vans:

Since the average distance travelled per day is 198km and the average distance travelled per litre is 9km, the van would use:

= 198/9

= 22 litres

Since there are 8 vans, they'll use:

= 22 × 8 = 176 liters

Trucks:

Since the average distance travelled per day is 620km and the average distance travelled per litre is 6.2km, the truck would use:

= 620/6.2

= 100

Since there are 10 trucks, they'll use:

= 100 × 10 = 1000 liters

The amount of liters for both the van and the truck will be:

= 176 liters + 1000 liters

= 1176 liters

The fuel cost will then be:

= 1176 × 1£1.29

= £1517.04
