Ella buys 5 packs of muffins. She uses a coupon and saves $3 off the total. Which expression represents her total cost?

A. 5m -3
B. 5 -3m
C.5+3
D. 5m + 3

Answers

Answer:

The answer is A. 5m - 3

Step-by-step explanation:

Ella bought 5 packs of muffins but since we don't know how many muffins are in each pack, we put a variable in place so it's 5m. Since she saved $3 off the total, that means you would subtract 3 from the total, so the problem would be 5m - 3

Paulo sells 249 medium pumpkins for $8 each and 84 large pumpkins for $14 each. How much money does Paulo collect selling the medium and the large pumpkins

Answers

Answer:  $3,168

Step-by-step explanation:

Paulo sells 249 medium pumpkins for $8 each. The money Paulo makes from this is:

= 249 * 8

= $1,992

Paulo also sells 84 large pumpkins for $14. The money made is:

= $1,176

Total from selling both is:

= 1,992 + 1,176

= $3,168

Maria makes a fruit salad.
The table shows the amounts of different kinds of fruit that she uses.
Kind of Fruit Amount
Grapes 323 cups
Melon 214 cups
Pineapple 234 cups
Strawberries ?
The amount of strawberries that Maria uses is 38 times the amount of the other fruits combined.
How many cups of strawberries does Maria use?

Answers

Answer:

If my calculations are correct it would be 6,168 cups of strawberries

Step-by-step explanation:

If it’s 8 times the amount of them combined then you add all of the other fruit together and then multiply by 8 giving you:

323+214+234=771

771*8=6,168 cups of strawberries.

Only in math would someone need that much fruit

y = a + x
y = 1 X
y = 4 + x
y = 4x

Answers

Answer:

The equation of the graph is;

y = 4·x

Step-by-step explanation:

The coordinates of two points, (x₁, y₁), and (x₂, y₂) respectively on the straight line graph are;

(-3, 12), and (2, 8)

The slope, m, of the straight line graph is given as follows;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Therefore, by substitution of the values, we have;

[tex]Slope, \, m =\dfrac{8-(-12)}{2-(-3)} = \dfrac{8 + 12}{2 + 3} =\dfrac{20}{5} = 4[/tex]

The equation of the graph in point slope form is therefore;

(y - 8) = 4×(x - 2)

y = 4·x - 8 + 8 = 4·x

y = 4·x.

Find x and y so the quadrilateral is a parallelogram.

Answers

Answer:

We conclude that:

The value of x = 7The value of y = 4

Step-by-step explanation:

Given

The parallelogram PQRS

We know that the diagonals of a parallelogram bisect each other.

so

[tex]RT = TP[/tex]

Given

RT = xTP = 5x-28

so substituting RT = x, and TP = 5x-28

[tex]RT = TP[/tex]

[tex]x = 5x-28[/tex]

[tex]5x = x+28[/tex]

[tex]5x-x = 28[/tex]

[tex]4x = 28[/tex]

divide both sides by 4

[tex]4x/4 = 28/4[/tex]

[tex]x = 7[/tex]

Therefore, the value of x:

x = 7

Similarly,

[tex]QT = TS[/tex]

Given

QT = 5yTS = 2y+12

so substituting QT = 5y, and TS = 2y+12

[tex]QT = TS[/tex]

[tex]5y = 2y+12[/tex]

[tex]5y-2y = 12[/tex]

[tex]3y = 12[/tex]

divide both sides by 3

[tex]3y/3 = 12/3[/tex]

[tex]y = 4[/tex]

Therefore, the value of y:

y = 4

Therefore, we conclude that:

The value of x = 7The value of y = 4
