A chemistry teacher needs to make a 42% sulphuric acid solution. The acid solutions available are 4 liters of 30% sulphuric acid and 50% sulphuric acid, by volume. How many liters of the 50% sulphuric acid solution must be mixed with the 4 liters in order to make the 42% sulphuric acid solution?
Answer:
4 liters of 30% and 6 liters of 50% acid.
Step-by-step explanation:
Let the volume of 30% acid be x, then the volume of 50% acid will be
(10 - x) liters.
So we have the equation:
0.30x + 0.50(10 - x) = 0.42* 10
0.30x + 5 - 0.50x = 4.2
0.80 = 0.20x
x = 4 liters.
So we need 4 liters of 30% acid and 6 liters of 50% acid.
Liz and Rick are squeezing lemons for a lemonade stand. Liz squeezed 18 lemons in 6 minutes. Rick squeezed 24 lemons in 12 minutes. Who squeezed lemons at a faster pace? ⇒

56+13 = 69
180-69 = 111
56+111 = 167
180-167 = 13

Which equation represents the relationship between the x-values and y-values in the graph?
The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (0, -5) and (5, -2).
Now,
Since, The equation of line passes through the points (0, -5) and (5, -2).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 2 - (-5)) / (5 - 0)
m = 3 / 5
m = 3/5
Thus, The equation of line with slope 3/5 is,
⇒ y - (-5)= 3/5 (x - 0)
⇒ y + 5 = 3x/5
⇒ y = 3x/5 - 5
Thus, The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5

What value of x makes the equation true
Answer:
A
Step-by-step explanation:
The equation in simple terms is 3x+2=-2x+6. This is because there are 3 triangles with x in them and 2 squares with 1 in them on the left side, and 2 triangles with -x on the right side with 6 1's. If you don't know how to solve this I'd be happy to go in full depth: subtract 2 from 6, subtract -2x from 3x this will give you 5x=4 and then you divide 5 from for giving you 4/5 or 0.8.

a = cost of 1 drink $12.75 + 4a $12.75 + $12.00 = $24.75
you could do this one tooo let x represent cost of soda
y = 4x + 12.75
and if you put the three dollars into x
y = 12 + 12.75

What are the slope and the y-intercept of the graph of the linear function shown on the grid?
Answer:
C
Step-by-step explanation:
Slope=rise/run
Y intercept is the where the line hits the y axis which is -1.5
Answer:
Slope: -1/4
y-intercept: -1.5
Step-by-step explanation:
First you do rise over run meaning you from the point (-2,2) you rise up 2 to reach the x axis which is where point -6,0 so you rise 2 points and run 6. since the line is negative it becomes -1/4 and y-intercept is where the line first touches the y-line which is -1.5. I hop this helps!
