Answer:

Hypothenus = 22

Step-by-step explanation:

From the question given above, we were told that the triangles are congruent (i.e same size). Thus,

AC = EF

BC = DE

To obtain the length of each Hypothenus, we shall determine the value of y and x. This can be obtained as follow:

For y:

AC = y + 3

EF = 2y + 1

AC = EF

y + 3 = 2y + 1

Collect like terms

3 – 1 = 2y – y

2 = y

y = 2

For x:

BC = 5x + 7

DE = 6x + 2y

y = 2

DE = 6x + 2(2)

DE = 6x + 4

BC = DE

5x + 7 = 6x + 4

Collect like terms

7 – 4 = 6x – 5x

3 = x

x = 3

Finally, we shall determine the length of each Hypothenus. This can be obtained as follow:

Hypothenus = BC

Hypothenus = 5x + 7

x = 3

Hypothenus = 5x + 7

Hypothenus = 5(3) + 7

Hypothenus = 15 + 7

Hypothenus = 22

OR

Hypothenus = DE

DE = 6x + 2y

y = 2

x = 3

Hypothenus = 6(3) + 2(2)

Hypothenus = 18 + 4

Hypothenus = 22

A band expects to put 16 songs on their next CD. The band writes and records ​50% more songs than they expect to put on the CD.
lara [203]

Answer:

<u><em>12</em></u>

Step-by-step explanation:

Add 50% of 16 to 16, 50% of 16 is 0.5 * 16 = 8, 16 + 8 = 24

Multiply 24 by 50%, or 0.5 to get 12

8x−5x+4−x=Ax+B
yawa3891 [41]

Answer:

A = 2

B = 4

Step-by-step explanation:

To get an infinite number of solutions, both lines should be the same.

This means

A1x+ B1 = A2x + B2

So,

8x−5x+4−x=Ax+B

2x +4 = Ax +B

With this, we know the value of the coefficients

A = 2

B = 4
