Answer:
Step-by-step explanation:
13 = 6+7
276*13 = 276*(7+6)
= 276*7 + 276 *6 {distributive property upod addition}
= 1932 + 1656
= 3588
1) Would be c+15 because you can combine 19-4
2) Would be m+2 because you can combine 12-10
X is the number of hours studied, so replace x with 3 in the equation:
y = 6.8(3) + 60
y = 20.4 + 60
y = 80.4
Round down to 80.
The answer would be A.
Y=6x because once you plug in the x value you’ll get the same y values as in the table
