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

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.

i cant fully remember all of the ranks, here are the ones i remember.
