Anna adds (8x + 12y) and (ax − 6y). If the correct answer is 5x + 6y, what is the value of a?

2 answers:

8 0

The answer is -3, Choice 1 because you only need to care about the x values, so what do you add/subtract from 8 you get 5? So the answer is -3

Answer:

A) -3

Step-by-step explanation:

Given,

When (8x + 12y) is added to (ax − 6y) the answer is (5x + 6y)

$(8x+12y)+(ax-6y)=(5x+6y)$

$8x+12y+ax-6y=5x+6y$

$(8+a)x+6y = 5x+6y$ ( By combining like terms )

By comparing,

$8+a = 5$

$\implies a = 5 - 8 = -3$

Hence, the value of x is -3,

Option A is correct.

Triangle ABC is dilated to produce triangle A'B'C' with scale factor 3/4. which describes the relationship between the two trian

Nadya [2.5K]

Answer:

ΔA'B'C' is a reduction of ΔABC and ΔA'B'C' is similar to ΔABC.

Step-by-step explanation:

It is given that the triangle ABC is dilated to produce triangle A'B'C' with scale factor 3/4.

If a figure is dilated then preimage and image are similar.

If scale factor is between 0 to 1, then preimage is reduction of image.

If scale factor is more that 1, then preimage is enlargement of image.

If scale factor is 1, then preimage is congruent to the image.

We know that

$\frac{3}{4}=0.75$

So,

$0$

Therefore, the ΔA'B'C' is a reduction of ΔABC and ΔA'B'C' is similar to ΔABC.

5. Use the Pythagorean theorem to estimate the length of the unknown side of the right triangle. Explain why

photoshop1234 [79]

Answer:

Step-by-step explanation:

a^2 + b^2 = c^2

6 = b

c= 8

a=?

now u just replace

a^2 + 6^2 = 8^2

a^2 + 32 = 64

a ^2 = 64-32

a^2 = 32

$\sqrt a^{2} = \sqrt32$

a = 5.65685424949

if you rounded

a = 5,7

GREYUIT [131]

Answer:

1. The circumference of any circle equals two times its radius multiplied by pi (π, approximately 3.14). We can also say it equals pi times its diameter.
