3x - 4y = 10
3x = 10 + 4y
3x -10 = 4y
3x - 10 = y
---------
4

first you add y so it will be positive
Then you take away the 10 so you get the subject on its own
then divide by 4 to get 1 y

3x-4y=10

or,4y=3x-10
or,y=(3x-10)/4

so,y=3/4 x-5/2

The line plot shows the weights of packages of meat available at a grocery store. The 3 lightest packages cost $4.40 per pound.
Mnenie [13.5K]

Answer:

$42.40

Step-by-step explanation:

The horizontal axis is in fractions.

The three lightest are two  \frac{5}{8} pounds & one  \frac{6}{8} pounds. Each cost $4.40 per pound.

So cost = 4.40(5/8+5/8+6/8) = $8.8

Remaining costs 4.80 per pound. We add up the remaining and multiply by 4.80 to get their cost.

cost = 4.80(1+1\frac{1}{8}+1\frac{1}{8}+1\frac{1}{8}+1\frac{2}{8}+1\frac{3}{8})=33.6

Hence, total cost =  8.8 + 33.6 = $42.40

Melissa used 4 cups of sugar to bake 54 cookies. If she’s only used 1 cup of sugar, what would be an equivalent ratio of cups to
daser333 [38]

Answer:

\frac{2}{27}

Step-by-step explanation:

We have given  that melissa used 4 cups of sugar to bake 54 cookies.

That means 1 cup of sugar will be used to bake \frac{54}{4}=\frac{27}{2} by unitary method

We have to find the ratio of cups to the cookies

We are using 1 cup of sugar

And cookies will be \frac{27}{2}

\text{equivalent ratio}=\frac{1}{\frac{27}{2}}=\frac{2}{27}

Mr North spent $144,00 to build a fence around the perimeter of bis vegetable garden.He paid $6.oo per yard for fencing.
NikAS [45]
First, you could see the amount of fence he could buy, or 144/6, which would be 24, so Mr. North can buy 24 yards of fencing.
So now to find the possible plans, we know that there are four sides, but the width and the length occur twice since it's a rectangle.
So since we know that, we can just split 24 in half to find the possibilities for one of the width sides and one of the length sides, if that makes any sense. 24/2 = 12.
So now, you could say some possibilities are length = 6 and width = 6, or length = 4 and width = 8.
And now, to consider which plan would be the best, it would probably be a 6x6 design, because it gives the biggest area to the vegetable garden, and is easy to move around.
width = 6
length = 6
area = 36 square yards (6×6)
perimeter = 24 yards (6+6+6+6)
