Break the problem down slowly
What info can we gather?
The woman says it rusts, so that is her main statement.
She uses her statement to make an assumption that because it rusts, it is not stainless steel.
Since she assumes it is not stainless steel, she thinks she did not get what she paid for, thus, her conclusion is that she should get a refund.
The best I could figure out with d is that the whole set is not stainless steel, so she should get a refund for the whole thing. The account says that some of the utensils have rusted, not all.
Hope this helps!
The answer is C.) m∠1+m∠2=m∠2+m∠3

Step-by-step explanation:
<u>Step 1: Define</u>
2x - 12 = -52
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 12 on both sides: 2x = -40
- Divide 2 on both sides: x = -20
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 2(-20) - 12 = -52
- Multiply: -40 - 12 = -52
- Subtract: -52 = -52
Here we see that -52 does indeed equal -52.
∴ x = -20 is the solution to the equation.
Answer:
9. a) 18 b) 4
10. a) 67.5g b) $75
Step-by-step explanation:
9. a) 3*n=(9*6), n=18
b) cross multiply and you will get 15n=60, n=4
10 a) 15% of 450=(15*450)/100=67.5
b) 125% of $60=(125*60)/100=75
