X= one dollar bills
Y= five dollar bills
X+y=60
Y=(60-x)

1x+5y=196

Substitute y
X+5(60-x)=196
X+300-5x=196
X-5x=196-300
-4x=-104
X=-104/-4
X=26
Y=34(60-26)

So, there are 26 one dollar bills
And 34 five dollar bills

Since it takes 9 metres to make 24 bows, we know that it takes 9 divided by 24 metres to make a bow. That leaves us with the fraction 3/8,
We take that and multiply by the number of bows to create, which is 16,
that gives us an answer of 6m,
OPTION C,
Hope this helps ;)

Which table does NOT represent a linear function
topjm [15]

TABLE D does NOT represent a linear function

<h2>Explanation:</h2>

The Table is shown below. Each table is a relationship between two variables, namely x and y. By plotting each table in a graphing tool we get:

TABLE A, FIRST FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{8-5}{-1-0} \\ \\ m=-3

TABLE C, SECOND FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{5-10}{-1-0} \\ \\ m=5

TABLE C, THIRD FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{1-2}{-1-0} \\ \\ m=2

TABLE D, FOURTH FIGURE:

It is not a linear function. It is likely this is a parabola that opens downward.

To make concrete it take 8 parts crushed gravel, 7 parts water and 5 parts cement mix. A worker needs to make 220 kg of concrete
Romashka-Z-Leto [24]

A complete load of concrete = 8 parts gravel + 7 parts water + 5 parts cement.

Total number of parts in every load = 8 + 7 + 5 = 20 parts

If total load = 220 kg, then       20 parts = 220 kg

Divide each side by  20 :             1 part = 11 kg

gravel   = 8 parts = 8 x 11 kg = <em>88 kg</em>
water    = 7 parts = 7 x 11 kg = <em>77 kg</em>
cement = 5 parts = 5 x 11 kg = <em>55 kg</em>

<u>Check:</u>    88 + 77 + 55 = 220         yay !

I don't know how to do this<br> Y=x-7<br> 3x-3y=21
lora16 [44]
You're going to use the substitution method for this.

First, we know that Y = x-7, so we can plug x-7 into everywhere we see Y!

3x - 3(x - 7) = 21

then we simplify

3x - 3x + 21 = 21
^      ^
These cancel out!
So we're left with...

21 = 21

That means that the solution to this equation is all real numbers!
