Answer:

1 1/2

Step-by-step explanation:

I would recommend using a mixed fraction calculator by calculator soup it really helps me with fractions.

Answer:

1 1/2

Step-by-step explanation:

First you take your expression:

(3/7)/(2/7)

-and because you are dividing a fraction by another fraction, it's basically multiplying the first fraction with the reciprocal of the second fraction.

So, we flip the second fraction upside down and multiply!

(3/7) * (7/2)

So, 3 * 7 = 21, and 7*2 = 14, making our total 21/14.

Next, we simplify our fraction by finding the GCF and dividing both sides of the fraction by the GCF, which is 7.

3/2

Lastly, we express it as a mixed number, 1 1/2

Marco purchased 2 boxes of cereal, 2 boxes of granola bars, and 3 packages of crackers. Each item cost c dollars. Marco wrote an expression for the cost of the cereal. Then he wrote expressions for the cost of the granola bars and the cost of the crackers. He used all of these to write an expression for the total cost. Which expression did Marco write to represent the total cost?

Answers

Answer:

c+c+c

Step-by-step explanation:

The expression to represents the total cost will be;

⇒ 3c dollars

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Marco purchased 2 boxes of cereal, 2 boxes of granola bars, and 3 packages of crackers.

And, Each item cost c dollars.

Now,

Since, Each item cost c dollars.

Hence, The cost of cereals = c

And, The cost of granola bars = c

And, The cost of crackers = c

Thus, The total cost = c + c + c

= 3c

find the solution for the system of linear equations by elimination: 2x+y=9,3x-y=16

Answers

Answer:

(-5,-1)

Step-by-step explanation:

2x+y=9 -> y=-2x+9

3x-y=16

3x-(-2x+9)=16

3x+2x-9=16

5x-9=16

5x-9 (+9)=16 (+9)

5x=25

x=5

no plug in 5 to x in any equation above

2(5)+y=9

10+y (-10)=9 (-10)

y=-1

so the answer is (-5,-1)

which is the graph of y=3/4x -3

Answers

Answer:

Step-by-step explanation:

the formula y = mx + b is used here

lets look at the formula we were given

y = 3/4x -3

the first number we see, 3/4x is the slope of the line, where 1 = a 45 degree angle towards the NORTH EAST corner from 0, in this case it is less then 1 so it is less steep then 45 degrees, how i remember is that i can plot a point using the numbers the the fraction in reverse and connect a line from 0,0 to that line

4,3 is a point that a line with this slope would cross, but not this line, because it does NOT start at 0,0 , instead it crosses the y-axis lower because we took some of b away, in this case -3, so the line moves down 3, not changing the slope

i hope this makes sence and you are able to use it in multiple problems like this, comment this if you have any questions
