Answer:
Exact Form:
83
+
12
√
35
Decimal Form:
153.99295739
Step-by-step explanation:
8. The answer is B because there are 12 inches in a foot. So, 9 x 12 = 108 but you need to add 3. So 111 will be the answer.
9. The answer is A. 1,311/23 = 57, you could use basic division for this.
H and J are out bc that's subtracting the 14 candy bars, which we just want to subtract the weight of the 10 oz of the box from 80 oz to get the total amount of candy bar ox, which equals 70 oz. Since you want to find how much each candy bar weighs you have to divide the difference between 14. - The answer is answer letter G.

<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
x - y = -1
3x + 5y = 21
<u>Step 2: Rewrite Systems</u>
x - y = -1
- Add <em>y</em> to both sides: x = y - 1
<u>Step 3: Redefine Systems</u>
x = y - 1
3x + 5y = 21
<u>Step 4: Solve for </u><em><u>y</u></em>
<em>Substitution</em>
- Substitute in <em>x</em>: 3(y - 1) + 5y = 21
- Distribute 3: 3y - 3 + 5y = 21
- Combine like terms: 8y - 3 = 21
- Add 3 to both sides: 8y = 24
- Divide 8 on both sides: y = 3
