Step-by-step explanation:

15 + 4(5y - 10)

4 x 5y = 20y

15 + -10 = 5

20y + 5

∆LMN ∼ ∆PON. What is the value of x? Select one: a. 28 1/3 b. 36 c. 20 d. 25
yawa3891 [41]

Answer:

Option B. 36

Step-by-step explanation:

From the figure attached,

ΔLMN ~ ΔPON

Therefore, corresponding sides of these similar triangles will be in the same ratio.

\frac{LM}{OP}=\frac{MN}{ON}=\frac{LN}{PN}

\frac{LM}{OP}=\frac{MN}{ON}

\frac{42}{14}=\frac{x}{12}

x = \frac{42\times 12}{14}

x = 36

Therefore, measure of side MN = x = 36 units

Option B. will be answer.

Samuel takes 5 hours to make a table and a chair. He takes 9 hours to make 3 chairs
nikklg [1K]

Answer:

3 hours

Step-by-step explanation:

t = time to make a table

c = time to make a chair

t + c = 5

t+3c = 9

Subtract the second equation from the first

t+3c = 9

-(t + c = 5)

-----------------------

       2c = 4

Divide by 2

2c/2 = 4/2

c =2

2 hours for the chair

t+c = 5

t+2 = 5

t = 5-2

t = 3hours

Help on how to do this problem​
siniylev [52]

Hello!

We can first find RZ. A midpoint is the point right in the middle of a line segment. It splits the line into two equivalent lengths. If z is the midpoint of RT, it therefore splits RT into two equivalent segments, RZ and ZT. Thus, the length of RZ is equivalent to ZT, therefore, the length of RZ is 150.

Next, find RT. We know that RT is made of RZ and ZT, and we know the side lengths of both - 150 and 150. Therefore, add these two together to get the length of RT. 150 + 150 = 300.

Finally, find x. We know that RZ is equal to 150, and we are given 8x - 10 = RZ. Therefore, we know 8x - 10 = 150. Solve this equation for x by isolating x.

8x - 10 = 150

8x = 160

x = 20

Therefore, x = 20.

Your final answer is choice C: x = 20, RZ = 150, and RT = 300.

Hope this helps!
