Answer:
Step-by-step explanation:
The amount of water in the mix is 2/(5+2) = 2/7 of the volume of the mix. That amount is ...
(2/7)(21 liters) = 6 liters
Then the other 21-6 = 15 liters are antifreeze.
A) To make the mix 1 : 1, 15-6 = 9 liters of water need to be added.
__
B) To make the mix 1 : 2, The total amount of water needs to be brought to 30 liters. 15 more liters need to be added for a total of 24 added liters of water.
Answer:
B. 3x -2y = 10
Step-by-step explanation:
The given line rises three units for each two units of run to the right. Hence its slope is 3/2. A parallel line will also have a slope of 3/2.
Of the equations we can see, selection B has a slope of 3/2. It can be rewritten in slope-intercept form as ...
3x -10 = 2y . . . . . add 2y-10 to isolate the y-term; next divide by 2.
y = 3/2x -5 . . . . . the coefficient of x is the slope
Answer:
0
Step-by-step explanation:
Well if y=3 then the equation is 2*3-6
Two times three is 6 and 6-6 is 0
The complete inequality is -2 < x < 35
<h3>How to determine the range of value of x?</h3>
The figure attached to the question is the given parameter
From the figure, we understand that:
Side length BA and side length BD are equal.
This is represented as:
BA = BD
Because the side length AC is less than the side length CD, then it means that:
The measure of the angle ABC is less than the measure of the angle CBD
This is represented as:
∠ABC < ∠CBD
Where
ABC = x + 2
and
CBD = 37
Substitute ABC = x + 2 and CBD = 37 in the inequality expression ∠ABC < ∠CBD
So, we have:
x + 2 < 37
Subtract 2 from both sides of the inequality
x + 2 - 2 < 37 - 2
Evaluate the differences
x < 35
From the question, we have the following incomplete inequality
-2 < x < [ ]
Complete the inequality as follows:
-2 < x < 35
Hence, the complete inequality is -2 < x < 35
