x = 8/-18 = -4/9

7. 20x= -2+4 = 2

20x=2 x= 1/10

8. 8x - 4 = -2

8x= -2+4 = 2

x= 2/8= 1/4

9. -6x-8= -2

-6x= -2+ 8 =6

x= -1

10. -x-3 = -10

-x= -10+3= -7

x=7

A cash register contains only five dollar and ten dollar bills. It contains twice as many five's as ten's and the total amount o

Effectus [21]

Answer:

Step-by-step explanation:

Let number of ten dollar bills be x .

So, number of five dollar bills = 2 x

Total amount of money in the cash register = 620 dollars

Amount of money in total cash as a result of five dollar bills = 2 x × 5 = 10 x dollars

Amount of money in total cash as a result of ten dollar bills = x × 10 = 10 x dollars

According to question ,

Total amount of money in the cash register = Amount of money in total cash as a result of five dollar bills + Amount of money in total cash as a result of ten dollar bills

⇒ 620 = 10 x + 10 x

⇒ 620 = 20 x

⇒ x = $\frac{620}{20}$ = 31

So, number of ten dollar bills = 31

IRISSAK [1]

Answer:

See below for answers and explanations

Step-by-step explanation:

4! = 4*3*2*1 = 24

0! = 1

2! + 3! = 2*1 + 3*2*1 = 2 + 6 = 8

3! * 4! = 3*2*1 * 4*3*2*1 = 6 * 24 = 144

10! / 7! = 10*9*8*7*6*5*4*3*2*1 / 7*6*5*4*3*2*1 = 10*9*8 / 1 = 720
