First find the side EC by setting up ratio. use pythagorean theorem to find the hypotenuse side.
Answer:
I can't submit a photo but here:
x = 4, y = 16
(4,16)
You can choose whichever format
Step-by-step explanation:
We have x given to us already. Since we know the value of x, we can input the value into the other equation to solve for y
Solve:
Substitute 4 for x:
- y = 2x + 8
- y = 2(4) + 8
- y = 8 + 8
- y = 16
Our solution is x = 4 and y = 16, or (4,16)

Answer:
The total cost would be: $62.14
Step-by-step explanation:
First convert the percent to a decimal, so since it is 4%, you move the decimal two places to the right, so it would be .04.
Next, multiply $59.75 x .04%. This equals $2.39.
Then, take the product and add it to $59.75. So, $59.75 + $2.39.
This equals $62.14!
Multiple choice questions = 5
True questions = 15
Given that:
Total number of questions = 20
Total worth of point = 100
Multiple choice questions (M) = 11 points each
True false questions (T) = 3 points each
Hence,
M + T= 20 ____(1)
11M + 3T = 100 ____(2)
M = 20 – T
Using the relation in (2)
11(20 – T) + 3T= 100
220 – 11T + 3T= 100
220 – 8T = 100
-8Tf = 100 – 220
-8T = – 120
T = 120/8
T = 15
Mc = 20 – 15
Mc = 5
Multiple choice questions = 5
True false questions = 15
3n+2 cause n times 3 equals 3n
