Answer:
2 7/12
Step-by-step explanation:
−512−−93=?
Since the the second fraction is negative and you are subtracting, remove the negative sign and switch the operation to addition.
The equivalent equation is
−512+93=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(-5/12, 9/3) = 12
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.
(−5/12×1/1)+(9/3×4/4)=?
Complete the multiplication and the equation becomes
−5/12+36/12=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
−5+36/12=31/12
This fraction cannot be reduced.
The fraction
31/12
is the same as
31÷12
Convert to a mixed number using
long division for 31 ÷ 12 = 2R7, so
31/12=2 7/12
Therefore:
−5/12−−9/3=2 7/12

Answer:
80 cookies
Step-by-step explanation:
To find the number of oatmeal cookies sold you would divide 72 by 9.
72 / 9 = 8
This means that 8 oatmeal cookies were sold at the bakery sale. The question wants you to find the combined amount of raisin and oatmeal cookies sold, so add 72 and 8 together.
72 + 8 = 80
80 raisin and oatmeal cookies were sold.
The slope of the line is undefined because the line doesnt pass through the origin. In order to calculate the slope the line must both be straight and pass through the origin.
