Write an equation for what it says:
:
1. The sum of 12 and the quantity 8 times a number k is equal to 48
12 + 8k = 48
8k = 48 - 12
8k = 36
k =
k = 4.5
:
Check solution:
12 + 8(4.5) = 48
12 + 36
:
:
2. The product of 9 and the quantity 5 more then a number t is less then 6
9(t+5) < 6
9t + 45 < 6
9t < 6 - 45
9t < -39
t <
t < -4
:
Test solution with a number slightly less than -4.33, say -4.5
9(-4.5+5) < 6
9(.5)
4.5 < 6
