Answer: the cost of one plate is $4.5
The cost of one cup is $2.1
Step-by-step explanation:
Let x represent the cost of 1 plate.
Let y represent the cost of 1 cup.
5 plates and 4 cups cost 30.90 dollars. It means that
5x + 4y = 30.9- - - - - - - -1
6 plates and 5 cups cost 37.50 dollars. It means that
6x + 5y = 37.5- - - - - - - -2
Multiplying equation 1 by 6 and equation 2 by 5, it becomes
30x + 24y = 185.4
30x + 25y = 187.5
Subtracting, it becomes
- y = - 2.1
y = 2.1
Substituting y = 2.1 into equation 1, it becomes
5x + 4 × 2.1 = 30.9
5x + 8.4 = 30.9
5x = 30.9 - 8.4
5x = 22.5
x = 22.5/5
x = 4.5
Answer:
the 2nd one (60m minutes)

Answer/Step-by-step explanation:
Two triangles can be proven to be congruent to each other if two angles and an included side of one triangle is congruent to the corresponding two angles and included side of the other triangle.
Two angles (<C and <A) in ∆ABC, are congruent to two angles (<D and <F) in ∆DEF. Also, the included side (AC) in ∆ABC is congruent to the included side (DF) in ∆DEF.
Therefore, based on the Angle-Side-Angle Congruence Theorem, ∆ABC is congruent to ∆DEF.
