1. Use the correct order of operations and do the exponents first.
Remember that an exponent of 2 means to multiply the base by itself, not multiply the base by 2.

<span>6^2+ 3^2 = 6 * 6 + 3 * 3 = 36 + 9 = 45

2. 4^3 + 4.5 = 4 * 4 * 4 + 4.5 = 64 + 4.5 = 68.5

2/3x - 1/2y = 3
Makovka662 [10]
The correct answer for this question would be the second option. <span>4x - 3y = 18 and x + 2y = 10. So in order to know why this is the answer, let us check it. Since the given numbers have fractions, let us eliminate the fractions.
2/3x - 1/2 y = 3 <<multiply both sides by 6
and we get 4x - 3y = 18 (So this one is correct)
Next,
1/2x + y = 5 << multiply both sides by 2 and we get
x + 2y = 10 (This one is correct too)
Hope this answer helps. </span>

Sphinxa [80]

Answer:

30 yards for 24 vs 1 foot for 25 cents

so lets multiple the yards by 3 to see how many feet

90 feet = 30 yards

90 feet 24 dollars

now lets divide 90 by 24

3.75 so 3.75 per foot

so the second one is way better

Hope This Helps!!!
