To figure out the percentage you got correct, we need to set up fractional proportions.
We already have one fraction, 14/20.
Since we are looking for a percentage, we need to have a maximum total percentage that represents the total score.
100% is the maximum percentage for any total.
So we have our fractional proportions set;
14/20 : x/100
To solve for this, we need to cross multiply the numerator (top number) of one fraction by the denominator (bottom number) of the other fraction.
Let's try this!
14 • 100 = 1400
20 • x = 20x
Now that we have our products, set them as an equation.
20x = 1400.
To solve for x, we need to divide both sides by 20.
20x / 20 = x
1400 / 20 = 70.
You are left with:
x = 70.
Your answer is:
If you get 14/20 on a test, you would get 70% of the questions correct.
I hope this helps!
Answer:
3) B
4) D
5) C
Step-by-step explanation:
3) Slope is before X
4) Set equal to Y
5) Use rise over run to find slope then find y intercept
The x - intercept is
and y - intercept is (0, 5)
<h3><u>Solution:</u></h3>
Given that : 3x + y = 5
<em><u>To find: x - intercept and y -intercept</u></em>
The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.
To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x
3x + 0 = 5
3x = 5

Therefore the x - intercept is 
To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y
3(0) + y = 5
y = 5
Therefore y - intercept is (0, 5)
