Mervin has some cartons of milk. He sold 2/5 of milk in the morning. He sold 3/4 of the remainder in the afternoon. 24 more cart
sergejj [24]

2/5 were sold in the morning. This is equal to 40% of the total.  That leaves 60% leftover.

 

3/4 were sold in the afternoon. This is equal to 75% of the 60% leftover or 45% of the total (.6x.75).

 

The difference between the two sales is 24 cartons or 5% (45%-40%). If 5% is equal to 24 then you can cross multiply to see what is the equivalent number of cartons out of 100%.

 

5/100 = 24/x

5x = 24(100)

5x = 2400

x = 480

 

ANSWER: 480 cartons

A car is traveling at a speed of 55 miles per hour.you want to write an algebraic expression to show how far the car will travel
goblinko [34]
Speed=Distance/Time
So Distance=Speed X Time
Distance=55T
Where 55 is the Car's speed and it is constant(won't change) and T is the time which is the changing variable.
you can plug time values to know the distance traveled!

ABCD ≅ FGHJ. Find the measure of the given angles or lengths of the given sides. CD = 2x + 3; HJ = 3x + 2.
xenn [34]
The question asks for the length of CD and HJ. To find those, we need to find a connection between them.

In the given statement, it says ABCD ≅ FGHJ. When we look at the equation, the corresponding letters are equal. For example, angle A is congruent to Angle F. Or BC ≅ GH.

So we know that CD and HJ are congruent.
Set them equal:
2x + 3 = 3x + 2
Subtract 2x from both sides:
3 = x + 2
Subtract 2 from both sides:
x = 3
If x is 3, plug it in:
3(3) + 2
Simplify:
9 + 2 = 11

So, HJ is 11. And because HJ ≅ CD, CD is 11 too.
