So if 1/3 0f the oranges equals 4, than you times it by three to get 3/3, so there were 12 oranges and 28 grapefruits, so the answer is 40

Mila [183]

Answer:

<em>(-3/5, 29/5) </em>

Step-by-step explanation:

Given the simultaneous equation;

-3x+4y=25...... 1

y= -3x+4 ..... 2

We are to confirm if (-3, 4) is the solution to the equations;

Substitute equation 2 into 1;

From 1;

-3x+4y=25

-3x + 4(-3x+4) = 25

-3x -12x + 16 = 25

-15x = 25 - 16

-15x = 9

x = -9/15

x = -3/5

Substitute x = -3/5 into equation 2 to get y;

From 2;

y= -3x+4

y = -3(-3/5)+4

y = 9/5 + 4

Find the LCM

y = (9+20)/5

y = 29/5

<em>Hence the solution to the system of equation is (-3/5, 29/5) hereby falsifying Julie's solution.</em>

Meiko is hanging a picture collage on her wall. The dimensions of the collage are shown in the diagram. She plans to cover
alexira [117]

Answer: \frac{A_{collage}}{15.75\ in^2}

Step-by-step explanation:

Since you did not attach the diagram and I don't know the dimensions of the collage, I will give you a general explanation of the procedure you need to use in order to solve the exercise:

1. You need to use the formula for calculate the area of a rectangle:

A=lw

Where "l" is the length and "w" is the width.

2. Using the formula, you must calculate the area of an small picture.

You know that its length is 4.5 inches and its width is 3.5 inches. Therefore, its area is:

A_{picture}=(4.5\ in)(3.5\ in)\\\\A_{picture}=15.75\ in^2

3. Calculate the area of the collage using the formula:

A_{collage}=(l_{collage})(w_{collage})

4. Finally, divide the area of the collage by the area of an small picture in order to find the number of small pictures that will fit within the collage:

\frac{A_{collage}}{15.75\ in^2}
