When you divide a number by a fraction, you should multiply the number by the reciprocal of the fraction. So if you make 1 1/3 an improper fraction you get 4/3. When you multiply 24 by the reciprocal, which is 3/4, you multiply it by the numerator and divide it by the denominator. So
(24 x 3) / 4
72 / 4
18

12345 [234]

Answer:

9.25 p + 8.90 t ≥ 100 describes the relationship between p and the t  for Michael to earn at least $100.

Step-by-step explanation:

p  =  Number of hours worked at the pet store

Earning per hour at pet store  =  $9.25

t = Number of hours worked as a telemarketer

Earning per hour at telemarketing job   =  $8.90

Now, total amount earned at pet store after working p hours = p x $9.25

and total amount earned at tele job after working t hours =  t x $8.90

Now, according to the question

Total money earned at pet store +  Total earning at telemarketing job = At least $100

⇒   9.25 p + 8.90 t ≥ 100

Hence,  9.25 p + 8.90 t ≥ 100 describes the relationship between p and the t .

1. Solve the following equation. -5p = -75
aliya0001 [1]

Answer:

15

Step-by-step explanation:

-5 x 15 = -75

This is according to the rule -a ÷ a = -a and -a x a = -a. Where a negative divided/multiplied by a positive number equals a negative number.

-75 ÷ -5 = 15

-75 ÷ 15 = -5

Write 5/8 and 9/14 so that they have a comon denominatr
valentina_108 [34]

The denominator is the bottom portion of the fraction. Example 4/6, the 6 is the denominator. The easiest way to start out in finding the common denominator is to see what number, 8 and 14, go into equally. Example: 1/4 and 1/3, 3 and 4 both go into 12. If you multiply 4 by 3 as well as 3 by 4 you get 12 both times. Now try it with 8 and 14.

What number can 8 and 14 go into equally? (56)

8x7=56...14x4=56

Nataliya [291]
F(C) = 9/5C + 32

I'll just change F(C) to y and 9/5C to 9/5x.
y = 9/5x + 32

inverse...

x = 9/5y + 32
9/5y = x - 32
y = 5/9x - 160/9

Sooooo
F(C) = 5/9C - 160/9
