Find x and y. Please help, I will give brainiest answer.

Answer:

x = 3 and y = 2

x = 1.25 and y = 1.75

Step-by-step explanation:

Part 1:

See the diagram first.

If the two arrow lines are parallel then, the two triangles are similar.

So, the corresponding sides of the triangles are proportional.

So, $\frac{3}{1.5} = \frac{6}{x} = \frac{4}{y}$

Hence, x = 3 and y = 2 (Answer)

Part 2:

See the diagram first.

If the two arrow lines are parallel then, the two triangles are similar.

So, the corresponding sides of the triangles are proportional.

So, $\frac{10}{8} = \frac{x + 5}{5} = \frac{y + 7}{7}$

⇒ $x + 5 = \frac{50}{8} =6.25$

⇒ x = 1.25

Again, $y + 7 = \frac{70}{8} =8.75$

⇒ y = 1.75

Hence, x = 1.25 and y = 1.75 (Answer)

If 50 apples cost $25, then 75 apples would cost how much?

NikAS [45]

Answer:

$37.5

Step-by-step explanation:

we can look at this problem using rates:

50=$25

25=$12.5

so we can add $12.5 to $25 because 50+25=75 so our answer, 12.5+25=37.5

$37.5
