Therefore, you get that the solutions of this equation are the following:
Then, the answer is:
This matches with the option C.
Answer:
16%
percentage is calculated by 100
A. 2500 × 1/100 = 25%
B. 4100 x 1/100 = 41%

For the second question, the answer would be A because the lines intersect at 2 and -1.4. For the first question, t+b is less than or equal to 20 and 15b+8b is greater than or equal to 150 is the answer because Nick can work <u>up to </u>20 hours and needs to make <u>at least</u> $150 per week so that answer fits best. That question is solved mostly by context clues.
all even numbers are composite except for 2
A composite number has factors in addition to one and itself. The numbers 0 and 1 are neither prime nor composite. All even numbers are divisible by two and so all even numbers greater than two are composite numbers. ... Therefore all numbers that end with five and are greater than five are composite numbers.
