17) x-8=11

18) 9-x=5

19) x+6=7

20) x+(-4)=-18

Step-by-step explanation:

17) The difference between a number and 8 is 11

Let number = x

then the equation will be:

x-8=11

Solving:

x-8=11

x=11+8\\x=19

18) Nine less than a number is five.

Let number = x

then the equation will be:

9-x=5

Solving:

9-x=5\\-x=5-9\\-x=-4\\x=4

19) Seven is equal to a number plus 6

Let number = x

then the equation will be:

x+6=7

Solving:

x+6=7\\x=7-6\\x=1

20) The sum of a number and -4 is -18

Let number = x

then the equation will be:

x+(-4)=-18

solving:

x+(-4)=-18\\x-4=-18\\x=-18+4\\x=-14

Alice Correa bought three yards of cloth to make a dress the cloth was on sale for a dollar 93 per yard how much did Alice pay f
alexandr1967 [171]
To solve for the total amount that Alice paid for the 3 yards cloth, multiply the cost per yard with the additional 5% to number of yards. 5% of 93 is 4.65. The total cost per yard of cloth is 97.65. Multiplying the total cost with 3 will give 292.95. Thus, Alice paid 292.95 dollars in total.
