Answer:
x + 2 < 42
Step-by-step explanation:
Minimum height for Crazy cart = 42 inches
x = height last summer
Number if inches grown since last summer = 2
Height now = x + 2 is still not yet up to 42 inches because he is not yet tall enough to get on crazy carts ride.
Representing as an inequality :
x + 2 < 42
Answer:
One Solution ; x=4.5
y=-1.5
Step-by-step explanation:
Line A: 2x+2y=8
÷<u>2</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>
x+y=4
Line B: x+y=3 -----> y=x-3
x+(x-3)=4
2x-3=4
2x=7
x=4.5
y=-1.5
The answer to your question is 0.2
You will need 252 mL of pure water to obtain 0.25 mL of the desired 25% solution.
If we add X amount of water to the solution, the total amount of solution is 375+X.
And that must be 25%.
<h3>
What is the amount of solute in the current solution?</h3>
The amount of solute in the current amount of solution is
0.6(375)=225.
That amount won't change by adding water.
So we set up the equation so that the amount of solute divided by the new total amount of solution equals 25%.
225/(375+X)=0.25
cross multiply and solve
225/0.25=(375+X)
900-375=X
X=525
The pure water will you need to add to obtain the desired solution is 525.
Then we check 225/(375+525)=0.25.
