Answer:

90, 540, and 190

Step-by-step explanation:

To write an equation or expression for the numbers, first define the variables.

The "first number" is x.

"6 times a first number" is 6x. This is the second number.

"100 more than the first number" is 100+x. This is the third number.

All together, they add to 820.

x+6x+100+x = 820

8x + 100 = 820

8x = 720

x= 90

So the first number is 90. The second number is 6x = 6*90 = 540. The third number is 100+x = 100+90 = 190.

Which statements about 12 ÷ 7 are true? Use the array to answer the question. Check all that apply.
AURORKA [14]

Answer:

The remainder is 5

Step-by-step explanation:

12 Divided by 7 equals 12 over 7 or 1.714285. 7 can only go into 12, one time. if we subtract 7 from 12 we get 5 which is the remainder. There is no way it can be 2 because 7 plus 2 equals 9. 1 x 7 + 5 equals 12 which isn't 1.714285. 2 x 7 + 4 equals 18 which also isn't 1.714285. Same with 2 x 5 + 5. That equals 15 which isn't 1.714285.
