I have worked out the answer to the question, I hope it helps you. Please do not forget to check if this answer if reliable, I am not always correct
4(q-10)=76
because the number of questions minus the ten he got wrong times four for each point
Answer:
(-2, 1).
Step-by-step explanation:
When f(x) = 0
4 + 2x = 0
2x = -4
x = -2.
Ehen f(x) = 6
4 + 2x = 6
2x = 6-4 = 2
x = 1.
Answer:
x= 12 y=2
Step-by-step explanation:
In order to convert a percent to the decimal, the number should be divided by 100 and remove the percentage sign.
<u>Step-by-step explanation:</u>
Percent stands for per hundred.
In order to convert a percent to the decimal, the number should be divided by 100 and remove the percentage sign.
Example – 75%
= 75/100
= 0.75
<u>To convert decimal to mixed fraction:</u>
1. Divide the given decimal number by the place of the decimal and remove the point from the numerator.
Example – 5.25
= 525/100
2. Simplify the fraction if possible.
Example = 525/100 = 21/4
3. Divide the numerator by the denominator.
On solving we get, 5 as the quotient and 1 as the remainder.
To convert into a mixed fraction = the remainder becomes the numerator and denominator remains the same
Mixed fraction becomes = 5 1/4
