49=7 times 7
28=2 times 2 times 7
therefor yo need at least two 7's and two 2's

7 times 7 times 2 itme s2=49 times 4=196
answer is 196
Answer:x=150
Step-by-step explanation:
Step 1: Subtract 1.2x from both sides.
0.8x+20−1.2x=1.2x−40−1.2x
−0.4x+20=−40
Step 2: Subtract 20 from both sides.
−0.4x+20−20=−40−20
−0.4x=−60
Step 3: Divide both sides by -0.4.
−0.4x
−0.4
=
−60
−0.4
step-by-step explanation: the increase = 204 - 120
