Hey there! :)

Answer:

A. x = 5.

Step-by-step explanation:

Starting with:

4x + 1 = 21

Subtract 1 from both sides:

4x + 1 - 1 = 21 - 1

4x = 20

Divide both sides by 4:

4x/4 = 20/4

x = 5.

What is 6 20/97 as a improper fraction?
pshichka [43]

Answer:

120/97

Step-by-step explanation:

When you're turning a mixed fraction into an improper fraction, you keep the denominator (bottem number) the same, but you times the numerator (top number) by the whole number (non-fraction number/left number)

6 * 20 = 120

Therefore it should be 120/97

This can not be simplified though (if I recall)

zhenek [66]

Answer:

The single discount rate equavalent is a discount of 40%.

Step-by-step explanation:

The multiplier for a increase of a% is 1 + a/100.

The multiplier for a decrease of b% is 1 - b/100.

Discount of 20%:

20% decrease:

1 - (20/100) = 1 - 0.2 = 0.8

Discount of 25%:

1 - (25/100) = 1 - 0.25 = 0.75

Series of discounts(20% and 25%):

0.8*0.75 = 0.6

1 - 0.6 = 0.4

The single discount rate equavalent is a discount of 40%.
