Please help! If the two triangles are similar, which equation represents the value of side x?

madam [21]

$x=\frac{p q}{m}$ equation represents the value of side x.

Solution:

The two triangles are similar.

If two triangles are similar, then the corresponding sides are in proportional.

$$\Rightarrow \frac{m}{p} =\frac{q}{x}$

Do cross multiplication.

$$\Rightarrow mx=pq$

Divide by m on both sides.

$$\Rightarrow \frac{mx}{m} =\frac{pq}{m}$

$$\Rightarrow x =\frac{pq}{m}$

Therefore, $x=\frac{p q}{m}$ equation represents the value of side x.

Bethany is working her way through school. She works two part-time jobs for a total of 23 hours a week. Job A pays $5.70 per hou

Lady bird [3.3K]

Step-by-step explanation:

x = number of hours A

y = number of hours B

x + y = 23

5.7x + 7.1y = 143.7

from the first equation we get

x = 23 - y

this we use in the second

5.7×(23 - y) + 7.1y = 143.7

131.1 - 5.7y + 7.1y = 143.7

1.4y = 12.6

y = 12.6/1.4 = 9

x = 23 - y = 23 - 9 = 14

she worked 14 hours on job A and 9 hours on job B.

What is the equation of the line that passes through the point (6,14) and is parallel to the line with the following equation? y

Korolek [52]

Answer:

$\displaystyle \boxed{y = -1\frac{1}{3}x + 22}$

Step-by-step explanation:

Parallel Equations have SIMILAR RATE OF CHANGES [SLOPES], so keep $\displaystyle -\frac{4}{3}$ as is and do this:

14 = −4⁄3[6] + b

14 = −8 + b

+ 8 + 8

_________

$\displaystyle 22 = b \\ \\ y = -1\frac{1}{3}x + 22$

I am joyous to assist you at any time.
