Number n is 25 less than 120% of itself. What is the value of n?

BARSIC [14]

Answer:

n = 125

Step-by-step explanation:

Step 1: Convert words into an expression

Number n is 25 less than 120% of itself. What is the value of n?

25 less than 120% of itself can be represented as: 1.2n - 25

n = 1.2n - 25

Step 2: Add Subtract 1.2 from both sides

n - 1.2n = 1.2n - 25 - 1.2n

-0.2n = -25

Step 3: Divide both sides by -0.2

-0.2n / -0.2 = -25 / -0.2

n = 125

Answer: n = 125

A company has two manufacturing plants with daily production levels of 7 x plus 19 items and 2 x minus 7 items, respectively. T

leva [86]

First plant produces 5x+26 items more than second plant daily

Step-by-step explanation:

Given

The expression for plant A will be:

$7x+19$

For plant B:

$2x-7$

In order to find that how much more items are produced by first plant we have to subtract the daily production of second plant from first plant

So,

= $7x+19-(2x-7)\\= 7x+19-2x+7\\= 7x-2x+19+7\\=5x+26$

So,

First plant produces 5x+26 items more than second plant daily
