Answer:
x = 52
General Formulas and Concepts:
Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define equation</u>
3x - 17 = 2x + 35
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 2x on both sides: x - 17 = 35
- Add 17 to both sides: x = 52
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 3(52) - 17 = 2(52) + 35
- Multiply: 156 - 17 = 104 + 35
- Subtract/Add: 139 = 139
Answer:
a. yes
b. no
c. yes
d. yes
Step-by-step explanation:
For a, 27 + 38 can be broken apart. 27 is broken up by adding smaller numbers (20 + 7 = 27) and the same is done with 38 (30 + 8 = 38), so A and C shows a way to add 27 and 38. In C, the numbers are just put into a different order. B is not a way to add 27 and 38, because the sum is different.
27 + 38 = 65, however 20 + 70 + 38 = 128. The addition problem for D is a way to solve for 27 + 38, because it is broken up differently than A and C. They instead added the 20 and 30 together first, then split up 15 (from 8+7) into 10 and 5. So D is a way to solve, because it gets the same answer as 27 and 38 :D
$2.80/5= $0.56 per can at the village market
$7.50/10= $0.75 per can at the sam club.
Therefore the village market is cheaper and better to buy
