For this case, the first thing we must do is define variables.

We have then:

x: initial amount of cards

We now write the equation that models the problem:

x - (\frac{1}{2}) x - (\frac{1}{4}) x = 75

(\frac{1}{4}) x = 75\\x = 75 * 4\\x = 300

Therefore, the initial amount of cards is 300

Answer:

Latoya had 300 cards at the beginning

Layota gave away half of her cards and a quarter of her cards, totaling a loss of three-quarters (75%) of her cards. Thus, we know that her remaining cards (75) are 25% of her original total, and thus the total (x) divided by four. We can put this into an equation like the one below, and simply multiply both sides by four to get the original amount of cards Layota started with, 300. 

x/4 = 75 

x = 300

What are the dimensions of the largest rectangular field that can be enclosed with 64m of wire?​
Natalka [10]

Step-by-step explanation:

perimeter = 2*length + 2*width

area = length*width

perimeter = 64

Rectangular means all the corners have to be right angles.

If we say it can be a square, then...

perimeter = 4*side

64 / 4 = side

side = 16 meters

So the dimensions would be 16 m x 16 m

Answer:

So, the initial number of apples is 7.

Step-by-step explanation:

The number of apples of An, Binh, and Chi are the same. An gave away 17 apples, Chi gave away 19 apples, so now Chi's apples are 5 times higher than the total remaining apples of An and Binh. How many apples did each of you have at first? (Solve the above problem by equation or system of equations)

Let the initial numbers of apples is a.

An gave 17 apples

Chi gave 19 apples

So,

x - 19 = 5 (x - 17 + x)

x - 19 = 5 (2x - 17)

x - 19 = 10 x - 85

9 x = 66

x = 7
