Answer:

$\frac{3x - 2}{2} = 5 \\ multipy \: both \: side \: by \: 2\\ \frac{3x - 2}{2} \times 2 = 5 \times 2 \\ 3x - 2 = 10 \\ add \: 2 \: to \: both \: side \\ 3x - 2 + 2 = 10 + 2 \\ 3x - 0 = 12 \\ 3x = 12 \\ divide \: both \: side \: \frac{3x}{3} = \frac{12}{3} \\ x = 4$

Answer:

s = -2400t + 17400

Step-by-step explanation:

Let's say t is the x value on a coordinate plane, and s is the y. Then, we have the points (0, 17400) and (6, 3000). The slope of these is 14400/-6 or -2400.

Now we just have the equation y = -2400x + b, and from the point (0, 17400) we can find that b is 17400. So, we have y = -2400x + 17400. Convert these back into t and s and you get your answer, s = -2400t + 17400.

Alan mixes 1 1/3 cups of milk with a can of condensed soup. He makes a total of 2 5/8 cups of soup. How many cups of condensed s

Sonja [21]

To find the amount of soup in the soup-milk mixture, we just need to subtract the amount of milk from the amount of soup-milk mixture.

2 5/8 - 1 1/3 = 1 7/24.

There were 1 7/24 cups of soup in the can.
Hope that helped =)
