=57x+79+−1(−30x+6)

=57x+79+−1(−30x)+(−1)(6)

=57x+79+30x+−6

Combine Like Terms:

=57x+79+30x+−6

=(57x+30x)+(79+−6)

=87x+73

Calculate the sum of 1/4 and 1/7

KonstantinChe [14]

Try to find the lowest common denominator. In this case it's 28, which makes our numbers as follows:

1/4 = 7/28
1/7 = 4/28

7/28 + 4/28 = 11/28

We can't simplify it so that's the result.

Use rounding or compatible numbers to estimate the difference 359-224

tiny-mole [99]

359 goes to 360
224 goes to 220
360-220=140
I moved the answer up one then down four the way I moved the original numbers, so 140 is actually down three of the actual answer which must be 143 then
