Answer:

Part A: 0.75 \times 8 + 1 \times x = 21

Part B : x = 15

Part C: Megan purchased 15 books.  

Step-by-step explanation:

Megan earns a rebate each month on completing surveys and books.

She earns $0.75 for each survey she completes and $1 for each book. Now, last month Megan completed 8 surveys and earned $21.

Part A: If Megan purchased x number of books last month, then the equation that will determine the number of books she purchased, is

0.75 \times 8 + 1 \times x = 21 .......... (1) (Answer)

Part B: Now, solving equation (1) we get,

6 + x = 21 {Since, 0.75 × 8 = 6}

⇒ 6 + x - 6 = 21 - 6 {Subtracting 6 from each side} {Subtraction property}

⇒ x = 15 (Answer)

Part C: Megan purchased last month 15 books. (Answer)

Step-by-step explanation:

GIven the expression

23x + 7 ≤5

Subtract 7 from both sides

Find the reciprocal of 3/5
Kisachek [45]
The reciprocal of 3/5 is 5/3.

To get the reciprocal of a fraction, just turn it upside down.

A fraction has a numerator, top number, and a denominator, bottom number.
To get the reciprocal of a fraction, just swap over the numerator and denominator.

If whole numbers, to get the reciprocal of whole number, just divide the whole number by 1 to make it into a fraction, then get the reciprocal of that fraction.

Law Incorporation [45]

Based on her results, if she flipped the coins another 50 times, she should expect to flip heads 20 times. If Jessica flips a coin 100 times and gets 40 times heads and the next time she flips a coin 50 times she should get 20 because, 100 divide 2 is 50 so you would have to divide 40 with 2 and get the answer of 20.
