Answers
Explanation: Since the triangles are similar, we can use the proportion 9/4=(12x+2)/(5x+1).
Cross multiplying 9*(5x+1) and 4*(12x+2) gives us 45x+9=48x+8.
Solving for x gives us 1/3.
You can check your work by plugging in x for the two equations, which gives us 6 (RS) and 8/3 (R’S’)
The scale factor is 4/9 (k) from 9k=4
6*4/9=8/3 and (8/3)/(4/9)=6
Answer:
RS = 6 feetStep-by-step explanation:
Use ratios of corresponding sides:
TS/T'S' = RS/R'S'Substitute and solve for x:
9/4 = (12x + 2)/(5x + 1)9(5x + 1) = 4(12x + 2)45x + 9 = 48x + 848x - 45x = 9 - 83x = 1x = 1/3Find the length of RS:
RS = 12x + 2 = 12(1/3) + 2 = 4 + 2 = 6 feetRelated Questions

Step-by-step explanation:
First find the value of Y=> 5y-8=3y+1
=> 5y-3y=1+8
=> 2y=9
=> y=4.5
Second find the value of X=> x+6=4x
=> 6=4x-x
=> 6=3x
=> x=(6/3)
=> x=2
Thus, x=2 and y=4.5 [Option C]

Lily needed to get her computer fixed. She took it to the repair store. The technician
at the store worked on the computer for 4.5 hours and charged her $193 for parts.
The total was $530.50. What was the cost of labor, per hour?
Answers
The cost per hour for the labor will be $75
Total amount charged = $530.50
Amount charged for parts = $193
Number of hours used = 4.5 hours
Let the amount charged per hour = x
Therefore, the equation to solve the question will be:
193 + 4.5(x) = 530.50
193 + 4.5x = 530.30
Collect like terms
4.5x = 530.50 - 193
4.5x = 337.50
Divide both side by 4.5
4.5x/4.5 = 337.50/4.5
x = 75.
The cost of labor per hour is $75

Answers
Answer:
a= 158
b=22
Step-by-step explanation:
First we have to find b in order to find a.
To find b we need to add up the two angles we know the value of and subtract it from 180.
90+68= 158
180-158=22
We know b is 22 because the sum of all angles in a triangle is always 180.
Now that we have b we can find a.
we know that a+b=180 so all we have to do is subtract 22 from 180 to get 158.
Answer:
b is 22° and a is 158°
Step-by-step explanation:
b can be calculated by angle sum property and a can be calculated using exterior angle sun property
