kenny made cookies. he used 7/12 of a cup of flour and 1/4 of a cup of sugar. how much more flour the sugar did kenny use?

Answers

ANSWER:

he used 1/3 cup more flour than sugar

EXPLANATION:

7/12 - 1/4 is the equation

multiply the numerator and denominator of 1/4 by 3 so the denominators are the same. it would be 3/12

7/12 - 3/12 = 4/12

simplify

4/12 = 1/3

1/3 cup is your answer i hope this helps!

Answer:

The answer is 4/12

Step-by-step explanation:

Since you can't simplify 7/12 you would multiply the denominator of 4 by 3 and the numerator of 1 by 3 getting the fraction of 3/12.

After that you'd subtract 7/12 by 3/12 to get an answer of 4/12 or 1/3.

Hope this helps! :>

Ok so a triangle normally equals 180, since the two sides are congruent it would be 75+75=150 which means x=30 OR 65+65=130 which means X=50. Maybe.

1. Thad bought 8 notebooks that cost $3.79 each. If he gave the cashier a $50 bill, how much change did he get back from the purchase?
2.Lucy purchases a car for $16,314.40. If she makes a payment each month for the next 40 months, how much will she pay each month. (enter your answer as $dollars.cents)

Answers

Answer:

Step-by-step explanation:

1. Cost of each notebook = 3.79

Cost of 8 notebooks = 3.79 x 8 = 30.32

Amount gave to cashier = 50

Change = 50 - 30.32 = 19.68

407.86
Og. Cost - $16,314.40
Months - 40
I divided $16,314.40 by 40 and got $407.86

Lucy will pay $407.86 dollars each month for 40 months.

pls help you will get brainliest, 5 stars, friend request, and 2 thanks from me <3

Answers

Answer:

88,164 / 24 = 3673.5   It's kinda hard to explain division, just divide by larger numbers than 24, but are also multiples of it, like 24,000 or 72,000 to make it easier and faster.

2 1/3 - 4/5 = 23/15 = 1 8/15

0.75 * 0.2 =  0.15

2.48 / 4 = 0.62

Ms. Lori had 15/8 or 1 7/8 pizza left

Step-by-step explanation:

18 / 4 = 4.5

Okay, you would know that 16 / 4 = 4.
So that solves 1 part. Next, you have to divide 2 / 4. Which would equal 0.5.

Then you add 4 to 0.5, which is 4.5!

Using the line AB, name two line segments.


1. AB, C
2. A, B
3. AC, AB
4. CB, B

Answers

3. AC, AB

Step-by-step explanation:

A line segment consists lf a line with two endpoints(dots). AC is a line segment and so is CB but that isn't an option sl the next best thing is AB because it is also a line segment

The line segments are AB, AC, and BC. Then the correct option is C.

What is a line segment?

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

A line segment in mathematics has two different points on it that define its boundaries.

A line segment is sometimes referred to as a section of a path that joins two places.

There are 3 points A, B, and C on the line.

Then the line segments are AB, AC, and BC.

Then the correct option is C.
