18+11v=w-13t
18+11-w=-13t
13t=w-11v-18
t=1/13w - 11/13v - 1 5/13
Hope this helps :)
That could mean anything from worthless ($0, like MY car) to $5,999.99 .
Answer:
you would add 6 ounces of water to 9 ounces of mix
Step-by-step explanation:
to find the ratio of water to pancake mix, divide 4/4 and 6/4 to find the unit ratio of water to each 1 ounce of mix.
6/4 = 0.66...
0.66... ounces of water is used per 1 ounce of mix.
0.66... * 9 = 6
this means that 9 ounces of mix would use 6 ounces of water.
We observe that a line will pass through 3 points, but to find a slope we only need two.
We see that it passes through points (assuming the scale of graph is 1 : 1)
and
.
We can use slope formula that applies for any line and produce the same slope for any two different points on the line

So the slope is -1 also it intersects y-axis at
so the general form of the linear function is

That is in your case

Hope this helps.
