A used book sale charged $7.50 for hardcovers and $1.25 for paperbacks. During the sale, 15 hardcovers were sold and the sale earned $166.25. Write and solve an equation to determine the number of paperbacks, p, that were sold. 20 points i think

Answers

Answer 1

Answer:

Answer:

43 paperback books

Step-by-step explanation:

7.50(15) + 1.25x = 166.25

112.50 + 1.25x = 166.25

Subtract 112.50 from both sides

(112.50 - 112.50) + 1.25x = (166.25 - 112.50)

1.25x = 53.75

Divide 1.25 from both sides

x = 43

Answer:

15 yards of ribbon does olivia need for 18 balloons

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity 1 such as 4 meter per seconds or 5 miles per hours.

As pert the statement:

Olivia ties 2.5 feet of ribbon onto one balloon.

⇒ $\text{unit rate per balloon} = (2.5)/(1) = 2.5$ ft ribbon

Use conversion:

1 feet = 1/3 yard

then;

2.5 ft = 0.833333333 yard

⇒ $\text{unit rate per balloon} = (2.5)/(1) = 0.833333333$ yard ribbon

We have top find how many yards of ribbon does olivia need for 18 balloons

$\text{Number of ribbons} = \text{Unit rate per balloons} * 18$

Substitute the given values we have;

$\text{Number of ribbons} = 0.83333333 * 18 = 15$ yards

Therefore, 15 yards of ribbon does olivia need for 18 balloons

A.1.4 × 105
B.0.32 × 103
C.5.62 × 210
D.11.2 × 101

Answers

A. 1.4 × $10^(5)$ is written correctly in scientific notation

0.32 × $10^(3)$ needs to be 3.2 × $10^(2)$

5.62 × $21^(0)$ is just wrong its always × 10

11.2 × $10^(1)$ needs to be 1.12 × $10^(2)$

There is always 1 number before the decimal and that number is always greater than 0 and the number after × is always 10

Answer:

A 1.4 × 105

What is the quotient of 2 1/5 divided by 6 3/5 in simplest form?

Answers

Good evening ,

______

Answer:

$(1)/(3)$

___________________

Step-by-step explanation:

Look at the photo below for the details.

The quotient of $2(1)/(5)$ divided by $6(3)/(5)$ in simplest form is $(1)/(3)$

To determine the quotient of 2 1/5 divided by 6 3/5 in simplest form,

First we will write the given fractions properly

That is, $2(1)/(5)$ divided by $6(3)/(5)$

Now, we will carry out the division operation

First, express the fractions in their improper form

$2(1)/(5) / 6(3)/(5) =(11)/(5) /(33)/(5)$

Then,

$(11)/(5) /(33)/(5)= (11)/(5) * (5)/(33)$

$=(11)/(33)$

$=(1)/(3)$ (in its simplest form)

Hence, the quotient of $2(1)/(5)$ divided by $6(3)/(5)$ in simplest form is $(1)/(3)$
