1) The product of a number and -7 is 63 2) 10 subtracted from a number is 15

3) two-fifths of a number is -12

4) 8% of a number is 20

5) the sum of twice a number and 17 is -1

6) nine less than the product of a number and -4 is 35

Step-by-step explanation:

let the no. be x

for 1,

x× -7 = 63

or, x= 63 ÷ -7

or, x = -9

therefore -9times -7 is 63.

for 2

by question

x -10= 15

or, x = 15+10

or, x = 25

therefore 25 minus 10 equals 15.

for 3

by question

(2/5) of x = -12

or, x = -12×(5/2)

r, x= -6×5

or, x = -30

therefore 2/5 of -30 is -12

for 4

by question,

8%of x = 20

or, 8x/100=20

or, 8x = 20×100

or, x = 2000÷8

or, x= 250

therefore 8% of 250 is 20.

for 5

by question,

2x+17 = -1

or, 2x = -1 -17

or, 2x = -18

or, x = -18 ÷ 2

or, x =-9

therefore -9 times 2 plus 17 equals -1.

for 6 dont know

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
