Answer:

one ten was traded for ten ones

Step-by-step explanation:

372 cannot be divided by 3 easily. However, 360 +12 can be divided by 3 easily, so it makes sense to trade one of the seven tens for ten ones. That will leave 6 tens, but give twelve ones.

370 +2 = 360 +12 . . . . where the "+" numbers are the numbers of ones

Compare the values of the underlined digits?

amm1812

The value of 7 in 26,475 is ten times greater than the value of 7 in 503,497.

This is because the first 7 is in the tens place and the second seven is in the ones place. Everytime you move to the next "place" you are basically making the number ten times smaller or greater.

Factor 12q^2+34q-28. Include list of factors.

Misha Larkins [42]

Answer:

2(2q+7)(3q-2)=0

Step-by-step explanation:

lets set up the equation equal to 0:

12q^2+34q-28=0

now, lets factor:

2(6q^2+17q-14)=0

2(2q+7)(3q-2)=0

now, lets find the solutions:

2q+7=0

2q=-7

q=-3.5

3q-2=0

3q=2

q=2/3
