Shannon used 5 quarters and 5 nickels.
I basically used the guess-and-check method, and you can verify it by multiplying each coin value by 5.

0.25 x 5 = 1.25
0.05 x 5 = 0.25
1.25 + 0.25 = 1.50

I think it makes it more easier if you simplify the inequality.

4x + 20 < 40        First subtract 20 on both sides

4x + 20 - 20 < 40 - 20

4x < 20     DIvide 4 on both sides to get the variable "x" by itself

x < 5    [x is less than 5, so x represents the numbers that are less than 5]

[Note:

If the sign is < or >, you use an open circle.

If the sign is ≤ or ≥, you use a closed circle.]

Your answer is the 1st option because the solution is any number that is less than 5

Marysya12 [62]

Answer:

76  14/20

(76  7/10) simplified

Step-by-step explanation:

First we make the denominator of the fraction equal

82  15/20

24  16/20

18   15/20

We then subtract

82 15/20 -  24 16/20

81  35/20 - 24 16/20 =

57  19/20

Then we add

57  19/20 + 18 15/20=

76  14/20

(76  7/10) simplified
