Using the lines that you have both read and white values:

Divide the red by the white:

16 / 10 = 1.6

40 / 25 = 1.6

The scale factor is 1.6.

So you have 1.6 L red paint / L white paint

Now multiply the amount of white paint by 1.6 to find the amount of red paint:

4 x 1.6 = 6.4

13 x 1.6 = 20.8

20 x 1.6 = 32

How many solution does this have and how do you solve it

Vadim26 [7]

Answer:

Infinite solutions

Step-by-step explanation:

To determine the number of solutions a system has, you need its slope. If the slopes are the same, check if the equations are equivalent or not.

To find the slope, rearrange the equation to isolate "y", which makes it slope-intercept form y = mx + b.

"x" and "y" represent points on the line.

"m" represents the slope, which is how steep a line is.

"b" represents the y-intercept (where the graph hits the y-axis).

Isolate "y" in both equations:

x + 3y = 0

3y = -x Subtract 'x' from both sides

y = -x/3 Divide both sides by 3.

y = $-\frac{1}{3}x$

The slope is -1/3.

9y = -3x

y = -3x/9 Divide both sides by 9

y = $-\frac{3}{9}x$ Reduce the fraction to lowest terms

y = $-\frac{1}{3}x$

The slope is -1/3, but the two equations are the same.

Since the equations are the same, or <u>equivalent</u>, the two lines are always touching. The solution of a system means where two lines intersect, or meet. Therefore, <u>there are infinite solutions</u>.

Answer:

x = 10 2/3

Step-by-step explanation:

The ratios of corresponding sides are the same, so we have ...

x/8 = 8/6

x = 8·(8/6) = 64/6

x = 10 2/3

When adding two numbers, such as 123 and 423, care is taken to first line them up and then add like digits. How does expanding t

Ivanshal [37]

Since a polynomial is where we have like terms such as (1 x 10²) and (4 x 10²), we can add these up using the distributive property to get (5 x 10²) but still keep the 10². For example, it's similar to if we had 2x²+3x²=5x². The x² is still there, but we add up the 2 and 3. Similarly, we can add these up for 10^1 and 10^0
