Answer:

x = 35

y = 7

Step-by-step explanation:

See how the image looks like two overlapping triangles. It is given that the triangles are congruent. Its easier to see whats what if you draw the triangles separately. I also flipped over the triangle on the right so they match. Record the given angle measures. Since A is 45° then D is also 45°. DBC is 30°, so we can find the missing angle in triangle DBC. Angles in a triangle add up to 180° so

C + 45 + 30 = 180

C + 75 = 180

C = 105°

This is angle DCB.

Now all the angles are marked. We can set up equations to find x and y. see image.

Step-by-step explanation:

Area= Length × Width

Area= x-6 × x-8

Area= (x-6)(x-8)

Area= x²-8x-6x+48

Area= x²-14x+48

A boy spent 20% of his money on books and 20% of the remainder on food.If he had $2000 left, how much money did he have at first
DENIUS [597]

Answer:

\$3,125

Step-by-step explanation:

Let s represent the amount of money he initially started with.

After he spent 20% on books, he will have 100\%-20\%=80\% of his initial money left. We can represent this as 0.8s.

Following that, the boy spends 20% of the remainder of his money on food. Similarly, he will have 100\%-20\%=80\% of the remainder of money he had left after he purchased the books. Therefore, he ends up with 0.8(0.8s)=0.64s of his money left.

Since we're given that he had $2,000 after all these transactions, we have the following equation:

0.64s=\$2,000

Divide both sides by 0.64 to isolate and solve for s:

s=\frac{2,000}{0.64}=\boxed{\$3,125}

Therefore, the boy had $3,125 to begin with.
