27. Solve the inequality
3(3x + 7) > 4-8(4 + 5x).

Answers

Answer:

x > -1

Step-by-step explanation:

Step 1:  Distribute

3(3x + 7) > 4 - 8(4 + 5x)

(3 * 3x) + (3 * 7) > 4 + (-8 * 4) + (-8 * 5x)

9x + 21 > 4 - 32 - 40x

Step 2:  Combine like terms

9x + 21 > 4 - 32 - 40x

9x + 21 > -28 - 40x

Step 3:  Add 40x to both sides

9x + 21 + 40x > -28 - 40x + 40x

49x + 21 > -28

Step 4:  Subtract 21 from both sides

49x + 21 - 21 > -28 - 21

49x > -49

Step 5:  Divide both sides by 49

49x / 49 > -49 / 49

x > -1

Answer:  x > -1

Let the variable s represent the amount Trey saved before mowing lawns.

Trey earns s dollars. Then he earns an additional $40. So far, he earns (s+40).
Then this amount is doubled: 2(s+40)
At the end, he has $234. So the equation is
2(s+40) = 234
2s + 80 = 234
2s = 154
s = 77

An arithmetic approach (solving using addition) could have the equation as
(s+40) + (s+40) = 234
s + 40 + s + 40 = 234
2s = 154
s = 77

B; 25.65+13.23+6.35=45.23

To do this mentally just add the 2 decimals places together first (1.23). Then just add the whole numbers (44). Then add the 2 numbers together, 44+1.23=45.23
