Solution: x=5, top angle=80, bottom angle=100

Step by step solution:
Since they are same side interior angles they are equal to 180 so we can set up an equation.
19x+5+17x-5=180
36x=180
x=5
Then plug in the x value in the original equations
19(5)+5=20(5)=100
17(5)-5=16(5)=80

Hope that helps :)

fgiga [73]

X= 12(.7)^x(exponent)
x is the doll you are on. For example if your looking for the height of the height of the doll after the 12 in. one then x=2 and so on

Fred can paint a house in 10 hours. Together, pat and Fred can paint a house in 8 hours. Which equation, when solved will produc

sattari [20]

Answer:

Pat t2 = 40 hrs

Step-by-step explanation:

Given:-

- Fred can paint a house in t1 = 10 hours.

- Pat can paint a house in t2 hours.

- pat and Fred can paint a house in T = 8 hours.

Find:-

Which equation, when solved will produce the number of hours need for pat to paint the house alone

Solution:-

- The number of people working on a particular activity " painting a house " is inversely proportional to time taken to complete the activity. tn = T. The relation for individual time taken ti to complete an activity.

Sum ( 1 / ti ) = 1 / T

Where, ti = The individual time for (ith) person

T = The total time taken to complete the time by i = n number of people.

- For n = 2,

1/t1 + 1/t2 = 1/T

1/10 + 1/t2 = 1/8

1 / t2 = 0.025

t2 = 40 hrs

- It takes Pat t2 = 40 hrs to complete painting the house.

10 have volunteered to help with the preparations for a party. How many ways can Susan assign someone to buy beverages, someone

Lesechka [4]

Answer:

The answer is 720 ways.

Step-by-step explanation:

Total friends who volunteered = 10

Total number of jobs that have to be done = 3

Here order matters, so it is a permutation question.

We can use the formula nPr.

= $\frac{10!}{7!}$

= 720 ways.

The second way to solve this is:

Susan can choose the first person to do a job in 10 ways

Then the second job can be done in 9 ways and the third in 8 ways.

Total becomes = $10\times9\times8=720$ ways

What is the equation of the line parallel to 3x + 5y = 11 that passes through the point (15, 4)?

soldier1979 [14.2K]

Answer:

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is 3x + 5y = 11

We must first write the equation in the general equation above

So we have

5y = - 3x + 11

Divide both sides by 5

Comparing with the general equation above

Slope = - 3/5

Since the lines are parallel their slope are also the same

Slope of parallel line = - 3/5

So the equation of the line using point

(15, 4) and slope - 3/5 is

We have the final answer as

Hope this helps you
