Answer: 17/24
Step-by-step explanation: Notice that 1/8 and 7/12 are unlike fractions. Our first step when adding unlike fractions is to get a common denominator.
The common denominator of 8 and 12 will be the least common multiple of 8 and 12 which is 24. To get a 24 in the denominator of 1/8, we multiply the numerator and the denominator by 3 which gives us 3/24. To get a 24 in the denominator of 7/12, we multiply the numerator and the denominator by 2 which gives us 14/24. Now we're adding like fractions.
3/24 + 14/24
To add like fractions or fractions that have the same denominator, simply add the numerators and keep the original denominator.
So here, if we add the numerators we have 3 + 14 which gives us 17. We put this over our original denominator which is 24. So we have 17/24.
So 1/8 + 7/12 is 17/24.

Answer:
Zeros are the values of x that make the function equal zero. ie x2−8x+12=0. Factor the quadratic and solve for x.

Answer:
16 cookies
Explanation:
If each box has 32 cookies then, 4•32=128
Then if Leslie divides them equally into 8 platters, 128/8 will equal 16.
Answer:

Step-by-step explanation:
Let
x ------> the next grade
we know that
To find the average grade sum the grades by the number of math test
so
solve for x
Combine liker terms in the right side
Multiply by 5 both sides
Subtract 372 both sides
-----> this is not make sense
The grade cannot be a negative number
so
For x=0
The minimum average grade is
