Martina combined different amounts of water, vinegar, and rubbing alcohol to make 38 milliliters (ml) of a solution for a science experiment. the amount of water was x ml. the amount of vinegar was 8 ml less than that of water, and the amount of rubbing alcohol was half the amount of vinegar. this is represented in the equation below: x + (x − 8) + one half (x − 8) = 38 what was the difference in the amounts of water and rubbing alcohol martina combined?

The difference in the amounts of water and rubbing alcohol Martina combined is 14 ml.

Step-by-step explanation:

Here, the given equation,

Where, 38 is the total amount of the solution,

x is the amount of water in the solution, ( in ml )

(x-8) is the amount of vinegar,

is the amount of rubbing alcohol,

From equation (1),

So, the difference in the amounts of water and rubbing alcohol Martina combined =

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
