Step-by-step explanation:
10.
a. y=30x + 50
b. 30(2.5)+50= 125
c. y= 60x+100
d. 60(2.5)+100= 250
Breaking apart means that you just take the tens from each number, and the ones from each number, then add them up.
The tens from your numbers are:
30 from 34
40 from 45
The ones from your numbers are:
4 from 34
5 from 45
Now, you have to add up the tens and ones separately.
30 + 40 = 70
4 + 5 = 9
Finally, you add up those 2 numbers that you got- 70 and 9
