7x+12+63=180
8x+12=180
Subtract 12 from both sides
8x= 168
=c=21
10x-40=50
Add 40 to both sides
10x=90
X=9
4x+72+2x-12=180
6x +60 =180
Subtract 60 from both sides
6x=120
X=20
<em>1</em>×<em>4+1=5
2</em>×<em>5+2=12
3</em>×<em>6+3=21
So, 8</em>×<em>11+8=96</em>

Answer:
15 + 5w ≥ 75
Step-by-step explanation:
Let the number of weeks be represented as w.
We are told from the question that:
Charles is saving $5 each week from his allowance. He already saved $15 from the money he earned from mowing his neighbor's lawn.
The word "at least" in mathematics means equal to or greater than and it is represented by the sign ≥
Therefore, our inequality equation is written as:
15 + 5w ≥ 75
