Answer: -6/25
Step-by-step explanation: The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(3/5, 21/25) = 25
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1. Finish the multiplication The two fractions now have like denominators so you can subtract the numerators.The two fractions now have like denominators so you can subtract the numerators. Then boom you have -6/25 good luckkkkkkk
I think its 4 because the lines intersect 4 times but its been too long since ive done nonlinear equations
When we say that 2y is 2 times greater than y, this means that if we divide 2y by 2 we will get the y.
Similarly, to know the decimal that is less that 0.8 by 10 times, simply divide 0.8 by 10 as follows:
decimal = 0.8 / 10 = 0.08
This means that 0.8 is 10 times larger than 0.08
First I found the number of adults by multiplying .60 by 700. It was 420. From there all I had to do was subtract it from 700. Revealing the number of children to be 280.
The answer is B
