Type an integer that could be a solution to x for both inequalities. 3x – 5 > 12 and 4x + 3 < 40

x> 17/3,   x < 37/4

Step-by-step explanation:

3x−5>12

Step 1: Add 5 to both sides.

3x−5+5>12+5

3x>17

Step 2: Divide both sides by 3.

4x+3<40

Step 1: Subtract 3 from both sides.

4x+3−3<40−3

4x<37

Step 2: Divide both sides by 4.

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).
