x-->volume of white vinegar you need to add to the mixture (measured in cups)
<span>then
the amount of the pure vinegar in the mixture will be -----> (10*0.1 + x) cups
t</span>he volume of liquid will be ---------> 10 + x
the concentration equation is-------> [(10*0.1 + x)/(10+x)]=0.50<span>multiply both sides by (10+x) and then simplify

</span>(10*0.1 + x)=(10+x)*0.50-----------> 1+x=5+0.50x-------> 0.50x=4
x=8

Jaqleen can unload a grocery truck twice as fast as Marco. Together, they can unload the truck in 5 hours. How long would it tak
amm1812

Jaqleen unloads a truck in x hours and Marco takes 2x hours.

Working together (x*2x) / (x+2x) = 5 hours

2x^2 / 3x = 5  Multiplying both sides by 3x equals 2x^2 -15x = 0

x = 7.5 hours

So Jaqleen takes 7.5 hours and Marco takes 15 hours

Double-Check (7.5 * 15) / (7.5 + 15) = 112.5 / 22.5 equals

5 hours Correct!!

Find the vale of x need help
babunello [35]

Answer:

x=45 degrees

Step-by-step explanation:

You can see based off of the markings on the 2 sides, that it is an isosceles triangle, so that means the 2 base angles are equal.

so 2x+90=180 degrees

so 2x=90 degrees

x=45
