Answer:
x=2
y=3
Explanation
1. Solve x + 2y = 8 for x:
x + 2y = 8
x+2y + − 2y = 8 + −2y(Add -2y to both sides)
x = −2y + 8
2. Substitute −2y + 8 for "x" in 5x − 2y =4
5x − 2y = 4
5 (−2y + 8) − 2y =4
−12y + 40 = 4 (Simplify both sides of the equation)
−12y + 40 + −40 = 4 + −40(Add -40 to both sides)
−12y = −36 (Divide both sides by -12)
y = 3
3. Substitute 3 for "y" in x= −2y + 8
x = −2y + 8
x = (−2) (3) + 8
x = 2 (Simplify both sides of the equation)
Answer:
x = 2 and y = 3
A. Reflection
B. Rotation
C. Translation
D. No Transformation

Step-by-step explanation:
Two angels are supplementary. The measure of the large angle is four more than three times the measure of the small angle. Find the measure of both angles.
Answer:
The measure of the two supplementary angles is
Small angle = x = 44°
Large angle = y = 136
Step-by-step explanation:
Supplementary angles are two angles whose measures add up to 180° .
Let
Small angle = x
Large angle = y
x + y = 180°.... Equation 1
The measure of the large angle is four more than three times the measure of the small angle
Hence: y = 4 + 3x
We substitute 4 + 3x for y in Equation 1
x + 4 + 3x = 180°
4x + 4 = 180°
4x = 180° - 4
4x = 176
x = 176/4
x = 44°
Solve for y
y = 4 + 3x
y = 4 + 3(44)
y = 4 + 132
y = 136°
Therefore, the measure of the two supplementary angles is
Small angle = x = 44°
Large angle = y = 136

A System of Equations has two or more equations in one or more variables Many Variables So a System of Equations could have many equations and many variables.
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.

The number of fish in a lake decreased by 25% between last year and this year. This year there are 45 fish in the lake. What was the population of last year
Answer:
The population of last year was 60.
Step-by-step explanation:
From the information given, as you know that the number of fish in a lake decreased by 25% between last year and this year, the amount of fish this year represents 75% of last year's population as: 100%-25%=75%. With that, you can use a rule of three to find last year's population tha would represent 100% given that 75% is equal to 45 fish.
75% → 45
100% → x
x=(100*45)/75= 60
According to this, the answer is that the population of last year was 60.

A teenager has $20 to spend at the fair. The teenager rides 5 roller coasters and has $13.75 left. Each roller coaster costs the same amount.
How much does each roller coaster cost to ride, in dollars and cents?
Answer:
Each ride costs $1.25
Step-by-step explanation:
$20 - $13.75 = $6.25
$6.25 / 5 = $1.25
Answer:
1.25 per ride
Step-by-step explanation:
Subtract 13.75 from 20. You get 6.25. Divide 6.25 by 5.

Harry's math test scores are listed below. 95, 90, 85, 40, 100, 100, 85, 90 Which measures of central tendency most closely describes Harry's overall performance on the math test?
Answer:
85.6%
Step-by-step explanation:
To get two overall performance of Harry, we need to calculate his average score.
Average is also known mean score.
Mean = sum of the score/Total math subjects offered
Mean = 95+ 90+85+40+100+100+85+90/8
Mean = 685/8
Mean = 85.6
Hence her overall performance is 85.6%
The measure of central tendency used is 85.6%

11-3(x+2)
Expand and simplify
Answer:
5-3x
Step-by-step explanation:
To expand this, we start with the distribution of -3 into the parentheses containing x+2
This leaves us with
11-3x-6
From here, simplifying involves combining like terms. The only like terms we have are the constant values 11 and -6
We combine them by subtracting 11-6 to get 5.
This leaves us with our answer,
11-6-3x
5-3x
An alternate way of writing this would be
-3x+5
But this would only be required if we were asked to express the answer in decreasing degree, so don't worry about that for now

A bouncy castle can be hired for party's. The cost is given by Cost=£4.70 times number of children + £86. What is the cost of the bouncy castle for 13 children. At a different party, the cost of hiring the bouncy castle was £165.90.How many children went to the party.
Answer:
A. £147.10
B. 17 children
Step-by-step explanation:
Let
Number of children = x
Cost of hiring a bouncy castle = £4.70 * x + £86
What is the cost of the bouncy castle for 13 children
Cost of hiring a bouncy castle = £4.70 * 13 + £86
= £61.1 + £86
= £147.10
How many children went to the party when cost of hiring bouncy castle = £165.90
Cost of hiring a bouncy castle = £4.70 * x + £86
£165.90 = £4.70 * x + £86
165.90 = 4.70x + 86
165.90 - 86 = 4.70x
79.9 = 4.70x
x = 79.9/4.70
= 17
x = 17 children
