Answer 1

Answer:

Answer:

1 5/6

Step-by-step explanation:

We first convert each mixed number to an improper fraction.

To change -6 7/8, we will ignore the negative at first. Multiply the whole number by the denominator:

6(8) = 48

Add the numerator:

48+7 = 55

Putting the negative back in, we have -55/8.

To change -3 3/4, ignore the negative at first. Multiply the whole number by the denominator:

3(4) = 12

Add the numerator:

12+3 = 15

Putting the negative back in, we have -15/4.

This gives us

-55/8 ÷ -15/4

To divide fractions, flip the second one and multiply:

-55/8 × -4/15

Multiply straight across:

(-55×-4)/(8×15) = 220/120

Simplifying this, we know that both 220 and 120 are divisible by 10; this gives us

22/12

Both 22 and 12 are even, so they are both divisible by 2. This gives us

11/6

6 will go into 11 one time, with 5 remaining; this gives us

1 5/6

When subtracting a positive from a negative, you add. So 90 - -2 is 92. My teachers always used to transform the two subtraction signs into an addition sign for visual assistance. Hope this helps

If f(x) is parallel to the line Y =3/4×+2/5
which function could be f(x)

Answers

Answer:

Any function that has the slope of 3/4

Reason:In order for the 2 functions to be parallel they must have an equal distance between them at all times ( meaning if one function has a slighty different slope, than the two will intersect and will no longer be parallel). So the only way for the two lines to be parallel is if the two functions have the same slope

11/14-?/4=4/14 show the missing number

Answers

Hey there, we keep the denominators the same because they are both common denominators, (14). 11-4=7, Therefore, the missing number is 7 because 11/14-7/14=4/14

the missing number is 2/4.
11/14 - 2/4 = 4/14.

Karl bought 3 1/2 gallons of milk that cost $2.70 per gallon.What was the total cost of the milk?

Answers

The total cost of milk purchased is the product of the cost per gallon and the number of gallons purchased which is $9.45

Given the Parameters :

Cost per gallon = $2.70

Number of gallons purchased = 3.5 gallons

Total cost of milk purchased = Cost per gallon × number of gallons purchased

Total cost of milk purchased = $2.70 × 3.5 = $9.45

Therefore, the total cost of milk purchased by Karl ls $9.45

3 1/2 gallons = 3.5
if it costs $2.70 per gallon then you can do
2.70*3.5 = 9.45

Therefore, it will cost $9.45 for 3 1/2 gallons
