You see the 2 in 542 is in the ones place as in 324 is in the tenth place now 1 is way different then 10 or 2 and 20 whatever term suits your temptations I hope this comes in handy for you if so and this helps you please rate this the brainiest answer XD
I'm guessing the % of syrup refers to the % of sugar it has, therefore:
20% = 20 / 100 = 0.2
0.2 * x = 0.5
x = 0.5/0.2
x = 2.5
She will have 2.5 lbs of syrup

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
r = 4s
r = 1/2s + 7
<u>Step 2: Solve for </u><em><u>s</u></em>
<em>Substitution</em>
- Substitute in <em>r</em>: 4s = 1/2s + 7
- Subtract 1/2s on both sides: 7/2s = 7
- Divide 7/2 on both sides: s = 2
<u>Step 3: Solve for </u><em><u>r</u></em>
- Define equation: r = 4s
- Substitute in <em>s</em>: r = 4(2)
- Multiply: r = 8
Answer:
64π square feet (the formula for the area is r^2π so you have to multiply 8 with itself and you get 64. 64×π is 64π)
