Answer:
Step-by-step explanation:
Lupita brought seven pounds of pretzels at a local wholesaler for 16.80. This means that the rate at which she bought one pound of pretzel at the local wholesaler would be
16.80 / 7 = $2.4 per pounds of pretzels
Her friend, Charles about 5 pounds of pretzels at the supermarket 12.75. This means that the rate at which Charles bought one pound of pretzel at the supermarket would be
12.75 / 5 = $2.55 per pounds of pretzels
Charles's reasoning is wrong because the rate at which he bought one pound of pretzel is higher than that of Lupita's

answer: 7
Answer:
15) x = 20
16) y = 45°, z = 30°
17) all 4 corners = 90°, all 4 sides are equal length, diagonals are perpendicular, diagonals bisect the corner angles.
We can't do the extra credit because we do not have a relationship about the side lengths. We just have angle information.
Step-by-step explanation:
15) 2x + 8 = 3x - 12
x = 20
16) 2y = 90°
y = 45°
3z = 90°
z = 30°
Answer:
- 3 + x = 21
X = 24
Step-by-step explanation:
- 3 + x = 21
X = 21 + 3
X = 24
