<span>We have 75 mL of 4% sugar solution.
We have to add a 30% sugar </span><span>solution to make a 50% </span><span>sugar solution.
75 * .04 + .30x = .50 * (75 +x)
3 + .30x = 37.5 +.50x
I can't get the equation to solve.
Did you type it correctly? For one thing, you have the percentages typed as .30 % and 4%. Are the decimal places in the correct positions?
Also, no matter how much 30% sugar solution you add, it will NEVER increase to 50%.

Answer
Slope(m) = -1
Step by step explanation
Slope (m) = (y2 - y1)/(x2 - x1)
Here p1 = (-2, 3) and p2 (1, 0)
x1 = -2, y1 = 3, x2 = 1, y2 = 0
Now plug in the values in the slope formula, we get
m = (0 - 3) / (1 - (-2))
m = -3/(1 + 2)
m = -3/3
m = -1
Therefore, slope = -1
Thank you.
Answer:
5/6
Step-by-step explanation:
Brainly is good and educational for me.
ANSWER:
In triangles BEC and AED
1)BC=AD(given)
2)Angle BCD= Angle ADC(given)
Then,Angles BCE=Angle ADE
3)Angle BEC=Angle AED(vertically opposite angles)
Thus,triangleBEC=~triangle AED( by AAS rule)
Thus,DE=CE (By CPCTC)
