Answer:
Answer = C
Step-by-step explanation:
When solving a two-step equation, you will always need to undo the addition and subtraction first.
Answer:
$1.23
Step-by-step explanation:
First start off by multiplying $0.62 by 4 to find out the total she paid for all four pounds of beans. This would give you $2.48 spent on beans. Subtract $2.48 from the total amount spent ($8.63). You now have $6.15 left on what she could have spent on 5 pounds of potatoes. Do $6.15 divided by 5 to get an answer of $1.23. Hannah paid $1.23 per pound for the potatoes.
- 1 < - x/3 < 1
1st. Multiply all parts by 3:
-3 < - 3x/3 < 3. Simplify the mid term:
-3 < -x < 3. Now multiply all terms by - 1. Note when you multiply by a negative number, you flip the inequality signs:
(-1)(-3) < (-1)(-x) < (-1)(3)
+3 > x> -3

Answers: x = 8 and x = -8</h3>
========================================================
Work Shown:
x^2 + 15 = 79
x^2 = 79-15
x^2 = 64
x = sqrt(64) or x = -sqrt(64)
x = 8 or x = -8
As the steps above show, we first subtract 15 from both sides. Then we apply the square root to get the two results. Don't forget about the plus minus.
