Answer:
yes
Step-by-step explanation:
If two angles of one triangle match two angles of another, all three angles must be the same, and the triangles are similar. Here, angles A and D are congruent, and angles C and F are congruent. Hence ΔABC ~ ΔDEF.
Answer:
7 x - 8 y = 5
x - 8 y = -13
6 x = 18 subtract equations
x = 3
7 (3) - 8 y = 5
8 y = 16 solve for y
y = 2
Solution : (3, 2)
Check:
3 - 8 * 2 = -13 agrees with second equation
Given:
Grocery store: 8 ounces of blueberries = $2.80
Farmer's market : 14 ounces of blueberries = $4.20
1 pound = 16 ounces.
Unit rate: per ounce
Grocery store: $2.80 ÷ 8 oz = $0.35 per ounce
Farmer's market: $4.20 ÷ 14 oz = $0.30 per ounce
Unit rate per pound
Grocery store: $0.35 per ounce * 16 ounces = $5.60 per pound
Farmer's market: $0.30 per ounce * 16 ounces = $4.80 per pound
The answer to your question is x = 8
