Word Problem On Division

1 answer:

6 0

Answer is 13-1/2 cups
Step by step
We know 1 cup is = 2/9 of a liter
We know we are working with 3 liters = how many cups
So first I want my 3 liters in a like denominator based fraction
1 liter is = 9/9 so 3 liters is = 27/9
I want to divide 27/9 by 2/9, the part of a liter that equals 1 cup
When I divide a fraction, I flip one fraction and multiply
27/9 x 9/2 = 243/18, simplify to 13-1/2 cups
Problem solved

You can check your work
Multiply 13-1/2 cups x 2/9
Change your whole number to a mixed fraction
27/2 x 2/9 = 54/18, simplify it equals 3 liters!

Determine whether y = 2x - 3 is a linear equation. If so, write the equation in<br> standard form.

beks73 [17]

Answer:

yes, y=2x-3 is linear

2x - y = 3 Standard Form

Step-by-step explanation:

since both the 'x' and 'y' variables have one as their exponents then this represents a linear equation

standard form: Ax + By = C

y = 2x - 3

subtract 2x from each side to get:

-2x + y = -3

divide each term by -1 to get (this is done so the leading coefficient is not negative)

2x - y = 3 Standard Form

Calculate the perimeter and area for the parallelogram if a = 2.8 ,b = 16.5 and h = 11.5

Nana76 [90]

Perimeter = 2(a+b)

= 2(2.8+16.5)

=2(19.3)

Perimeter = 38.6

Area=base x height

=2.8 x 11.5

=32.2
