The sum of 88 elephants and x
elephants is 145 elephants.

Answers

57 elephants = x
Hope this helps

Answer:

x=57

Step-by-step explanation:

To solve this problem we need to make an equation to use to solve x.

The sum of 88 and x will equal 145 so the equation will look like this, 88 + x = 145.

Whatever x is, it has to add with 88 to make 145 so we have to use reverse operations.

The opposite of addition is subtraction so we subtract 88 from 145 like so. 145 - 88 = 57, which means x = 57.

Boxes of Valentine’s Day chocolate truffles come in a variety of sizes. The dimensions of the box you decided to purchase are 15 inches by 12 inches by 1.5 inches. If each truffle in this box has a volume of 2 cubic inches, how many truffles are included in the box?
A.

Answers

Answer:

135.

Step-by-step explanation:

Volume of the box = 15*12*1.5

= 270 in^3.

So the number of truffles = 270 / 2

= 135.

The number of truffles in the box is 135.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The dimensions of the box = 15 inches x 12 inches x 1.5 inches.

The dimension of each truffle = 2 cubic inches

The number of truffles included in the box.

= (15 x 12 x 1.5) / 2

= 270/2

= 135

Thus,

The number of truffles in the box is 135.
