2. Ashley had a summer lemonade stand where she sold small cups of lemonade for $1.25 and large
cups for $2.50. If Ashley sold a total of 155 cups of lemonade for $265, how many cups of each
type did she sell?

Answers

Answer:

[tex]\boxed {\boxed {\sf 98 \ Small \ Cups}}\\\\\boxed {\boxed {\sf 57 \ Large \ Cups}}[/tex]

Step-by-step explanation:

Let's make a system of equations.

First, define the variables.

Let s= small cups and g= large cups

Next, make 2 equations. 1 for the money and 1 for the number of cups.

Money

A small cup costs 1.25 and a large cup costs 2.50. The total money made is 265. 1.25s+2.50g=265

Number

A total of 155 cups of lemonade were sold. The sum of small cups and large cups sold will equal 155. s+g=155

Here is our system of equations:

[tex]1.25s+2.50g=265 \\s+g=155[/tex]

Now, solve. Let's isolate a variable in the 2nd equation, so we can plug it in after.

Subtract g from both sides of the equation. s+g=155 s+g-g=155-gs=155-g

Now we know that s is equal to 155-g. We can substitute (155-g) in for s in the first equation.

[tex]1.25s +2.50g=265[/tex]

[tex]1.25(155-g)+2.50g=265[/tex]

Distribute the 1.25

1.25(155-g)= (1.25*155)+ (1.25*-g)= 193.75-1.25g

[tex]193.75-1.25g+2.50g=265[/tex]

Work to isolate the variable. Subtract 193.75 from both sides of the equation and combine like terms on the left.

[tex]193.75-1.25g+2.50g=265-193.75[/tex]       (Subtract 193.75)

[tex]-1.25g+2.50g=265-193.75[/tex]      

[tex]1.25g=71.25[/tex]      (Combine like terms).

1.25 and g are being multiplied. The inverse of multiplication is division. Divide both sides by 1.25

[tex]1.25g/1.25=71.25/1.25\\g=71.25/1.25\\g=57[/tex]

Now we know that 57 large cups were sold. Plug 57 back into the original second equation to find the small cups.

[tex]s+g=155[/tex]

[tex]s+57=155[/tex]

Subtract 57 from both sides of the equation to isolate the variable, s.

[tex]s+57-57=155-57\\s=155-57\\s=98[/tex]

Ashley sold 57 large cups and 98 small cups.

small cup she sold = x = 98

large cup she sold = y =57

x = 70/2

x = 35

m\angle ABC = (3x - 70)\degree \\\\

m\angle ABC = (3\times 35- 70)\degree \\\\

Given:

A line passes through the two points [tex](4,1)[/tex] and [tex](8,2)[/tex].

To find:

The slope-intercept form of the line.

Explanation:

The slope-intercept form of a line is:

[tex]y=mx+b[/tex]

Where, [tex]m[/tex] is slope and [tex]b[/tex] is the y-intercept.

The line passes through the two points [tex](4,1)[/tex] and [tex](8,2)[/tex]. So, the equation of the line is:

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-1=\dfrac{2-1}{8-4}(x-4)[/tex]

[tex]y-1=\dfrac{1}{4}(x-4)[/tex]

Using the distributive property, we get

[tex]y-1=\dfrac{1}{4}(x)+\dfrac{1}{4}(-4)[/tex]

[tex]y=\dfrac{1}{4}x-1+1[/tex]

[tex]y=\dfrac{1}{4}x[/tex]

Therefore, the slope-intercept form of the line is [tex]y=\dfrac{1}{4}x[/tex].

Figure PQRS is a parallelogram.

Parallelogram P Q R S is shown. Angle Q is (x + 15) degrees and angle R is (6 x minus 10) degrees.

What are the measures of angles P and S?

∠P = 20°; ∠S = 160°
∠P = 40°; ∠S = 140°
∠P = 140°; ∠S = 40°
∠P = 160°; ∠S = 20°

Answers

∠P = 40°; ∠S = 140° answer

Step-by-step explanation:

The measures of angles of the parallelogram are ∠P = 140°; ∠S = 40°

What is a Parallelogram?

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The four types are parallelograms, squares, rectangles, and rhombuses

Properties of Parallelogram

Opposite sides are parallel

Opposite sides are congruent

Opposite angles are congruent.

Same-Side interior angles (consecutive angles) are supplementary

Each diagonal of a parallelogram separates it into two congruent triangles

The diagonals of a parallelogram bisect each other

Given data ,

Let the parallelogram be represented as PQRS

Now , the measures of angles of parallelogram are

The measure of m∠Q = ( x + 15 )°

The measure of m∠P = ( 6x - 10 )°

where ∠Q and ∠R are supplementary to each other

For a parallelogram , same-side interior angles (consecutive angles) are supplementary

On simplifying , we get

m∠Q + m∠P = 180°

( x + 15 ) + ( 6x - 10 ) = 180

7x + 5 = 180

Subtracting 5 on both sides , we get

7x = 175

Divide by 7 on both sides , we get

x = 25

And , the measure of ∠Q = 40° = measure of ∠S

The measure of ∠R = 140° = measure of ∠P

Hence , the measures of angles of parallelogram are solved
