Answer:

54

Step-by-step explanation:

55 + 74 + 78 + z + z + 45 = 360

252 + 2z = 360

2z = 108

z = 54

Answer: 288

Step-by-step explanation:

78+74+55=207

The degree of a pentagon is 540°

so 540-207=333

so z has to be 333 but the question says +45 and that would make 333 become 378 and we need to get exactly to 333 so the answer cant be 333 but a number that 45 can be added to ,to make 333 for example 54+45=99 so 54 isnt the answer,next is 144+45 which is 189 that doesnt equall 333 so that isnt the answer either lastly is 288+45 which is 333 Thats the answer ...

Tracy purchases cotton candy in a ratio of 2 pink to 7 blue to sell at a carnival. She has a total of 108 bags. How many bags of each color does she have?

Answers

Answer:

24 pink

84 blue

Step-by-step explanation:

2 + 7 =9

2/9 = x/108

108 ÷ 9 = 12

12 × 2 =24

24 pink

7/9 = x/108

108÷9 = 12

12 ×7 =84

The first equation in a system is 5x + 2y = –4. Which equation gives a system with no solution? A. y = 2x + 6 B. y = 1/4x – 2 C. y = 2x + 7 D. y = –5/2x – 3

Answers

Given:

The first equation of the system of equations is

[tex]5x+2y=-4[/tex]

To find:

The equation that gives a system with no solution.

Solution:

We have,

[tex]5x+2y=-4[/tex]

It can be written as

[tex]2y=-5x-4[/tex]

[tex]y=\dfrac{-5x-4}{2}[/tex]

[tex]y=-\dfrac{5}{2}x-2[/tex]

On comparing this equation with slope intercept form [tex]y=mx+b[/tex], we get

[tex]m=-\dfrac{5}{2},b=-2[/tex]

It means the slope of the line is [tex]-\dfrac{5}{2}[/tex] and the y-intercept is -2.

Slope of parallel lines are same but the y-intercepts are different.

From the given options, the slope of the line is [tex]-\dfrac{5}{2}[/tex] only in option D and the y-intercept is -3 which is different from -2.

The line [tex]y=-\dfrac{5}{2}x-3[/tex] is parallel to the given line and parallel lines have no solution. So, the second equation of the system of equations is [tex]y=-\dfrac{5}{2}x-3[/tex].

Therefore, the correct option is D.

At the market you can buy 6 bags of apples for $25. At the orchard you can get 8 bags of apples for $35. Which is the better deal?

Answers

Answer:

6 bags for $25

Step-by-step explanation:

25/6 = 4.16666666667 = $4.17 per bag

35/8 = 4.375 = $4.37 per bag

The better deal for the bags of apples is at the market

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

To determine which is the better deal, we can compare the prices per bag of apples at the market and the orchard.

At the market:

Price of 6 bags of apples = $25

Price per bag of apples = $25 / 6 ≈ $4.17 (rounded to two decimal places)

At the orchard:

Price of 8 bags of apples = $35

Price per bag of apples = $35 / 8 ≈ $4.38 (rounded to two decimal places)

Comparing the two prices per bag of apples, we can see that the price per bag at the market is $4.17, while the price per bag at the orchard is $4.38.

Hence , the better deal is at the market where you can buy 6 bags of apples for $25, resulting in a lower price per bag compared to the orchard.

Cody bought two pairs of gloves and four hats for $43. Tori bought two pairs of gloves and two hats for $30. What are the prices for the gloves and hats? Write a system of equations!

Answers

Answer:

2g + 4h = 43

2g + 2h = 30

Step-by-step explanation:

Answer:

pairs of gloves = x

hats = y

2x + 4y = 43

2x + 2y = 30

hats = $6.50

gloves = $8.50

Step-by-step explanation:

use the elimination method to solve this system.

subtract the first equation by the second.

2x + 4y = 43

- 2x + 2y = 30

--------------------

         2y = 13

y = 6.5

plug in the y value to find x

2x + 4 (6.5) = 43

2x + 26 = 43

2x = 17

x = 8.5

In a pet store,the ratio of dogs to cats is 3 to 2. if there are 15 dogs, how many cats are there at the pet store? NEED HELP ASAP

Answers

Answer:

10 cats

Step-by-step explanation:

dogs:cats = 3:2=15:x

3x=15.2

3x=30

x=10 cats

since the ratio is 3:2, you can set up your equation like 3/2 = 15/x. then cross multiply and that will get you 30 = 3x and x will equal 10. this means that there are 10 cats and 15 dogs. hope that helps!
