Answer:

The cost of one balloon is 4 dollars

the cost of one cake is 6 dollars

Step-by-step explanation:

The way I did it was by substituting different numbers and seeing if they equaled forty or 26.

my thought process:

1 balloon= 5

1 cake= 10

that doesnt work for 2 balloons and 3 cakes

1 balloon=5

1 cake=5

that works for 4 balloons and 4 cakes but not 2 balloons and 3 cakes

1 balloon=4

1 cake=7

I'm sorry I'm way too tired to finish this 0-0 anyways yeah that's the correct answer :)

Answer:

880 rotations or D

Step-by-step explanation:

72 inches = 72 / 12 = 6 feet

1 mile = 5280 feet

1 rotation covers 6 feet

x rotations covers 5280 feet

1/x = 6/5280                       Cross multiply

6x = 5280 * 1                      Divide by 6

x = 5280 /6

x = 880

Answer:

1/9

Step-by-step explanation:

Answer: (a) 13 (b) 1

Step-by-step explanation: The absolute value of -6 is 6. That equal 6 plus 7 which is 13. In the second equation, add -6 and 7 first. That is 1 and the absolute value of 1 is 1.

Answer:

A.13 b.-1

Step-by-step explanation:

a 6+7=13

b 6- -7=-1

angle1 + angle2 = 180

[tex]4x + 20 + x + 20 = 180[/tex]

[tex]5x + 40 = 180[/tex]

[tex]5x = 180 - 40[/tex]

[tex]5x = 140[/tex]

[tex]x = \frac{140}{5} [/tex]

[tex]x = 28[/tex]

Step-by-step explanation:

GCF of 27 and 45 is 9

Answer: 9 (3+5)

Step-by-step explanation:

The GFCF of these two numbers is 9 as they can both be divided by it

Distributive property form is when you place the GFC outside parenthesis so that the equation can be multiplied in order to show the original equation and dividing the numbers by the GCF so that it does not give you a larger number than what you started with

27/9=3 + 45/9=5

So, keeping this in mind the distributive property form would be 9(3+5)

Answer 9(3+5)

Answer:

w<4

Step-by-step explanation:

divide both sides by 8. no need to flip the sign because 8 is positive

8/8w<32/8

w<4

Answer:

w>4

Step-by-step explanation:

8w<32

8w/8=w

What you do to one side, do to the other.

32/8=4

w<4

Flip the sign because we divided.

w>4 is your answer

Answer:

A.

Step-by-step explanation:

Answer:

a. Domain -4 ≤ x ≤ 3, Range 0 ≤ y ≤ 5

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

According to the graph, we see that our x-values span from -4 to 3. Since both dots are closed dots, they are inclusive in the domain:

[-4, 3] or -4 ≤ x ≤ 3

According to the graph, we see that our y-values span from 0 to 5. Since both dots are closed dots, they are inclusive in the range:

[0, 5] or 0 ≤ y ≤ 5

Answer:

2 acute, 1 obtuse, 1 right

Answer:G

G is the correct inequality.

Answer:

It is the first answer

Step-by-step explanation:

For it to be considered a function, each x-value can only corresponds (have) one y-value, however, y-values (even if they are the same y-value) can have multiple different x-values.

Answer:

657 pounds

Step-by-step explanation:

Given

Represent the amount of fertilizer with x and the yield with y.

So, we have:

[tex](x_1,y_1) = (70,630)[/tex]

[tex](x_2,y_2) = (100,900)[/tex]

Required:

Determine the yield (y) when fertilizer (x) is 73ft^3

Using linear interpolation, we have:

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

Substitute the x and y values using

[tex](x_1,y_1) = (70,630)[/tex] and [tex](x_2,y_2) = (100,900)[/tex];

We have:

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

[tex]y = 630 + (x - 70)\frac{(900 - 630)}{(100 - 70)}[/tex]

[tex]y = 630 + (x - 70)\frac{270}{30}[/tex]

[tex]y = 630 + (x - 70)*9[/tex]

Open bracket

[tex]y = 630 + 9x - 630[/tex]

[tex]y = 9x - 630+630[/tex]

[tex]y = 9x[/tex]

To solve for y when x = 73.

We simply substitute 73 for x

[tex]y = 9x[/tex]

[tex]y = 9 * 73[/tex]

[tex]y = 657[/tex]

Hence, the yield for 73 cubic feet is 657 pounds

Answer:

What is meant by K-coloring algorithm to be "almost" constant-time: is that the pattern through which K-coloring algorithm is applied when coloring a graph is "almost" the same every time the algorithm is applied on any graph

Step-by-step explanation:

What is meant by K-coloring algorithm to be "almost" constant-time: is that the pattern through which K-coloring algorithm is applied when coloring a graph is "almost" the same every time the algorithm is applied on any graph. this is because in the use of K-coloring algorithm no adjacent vertices are colored  with the same color and if that happens the  lowest numbered color that has not been colored will be applied i.e. a new color.

The aim of the K-coloring algorithm is to color a graph with the least possible amount of different colors while ensuring that adjacent vertices don't get the same color

Step-by-step explanation:

Answer:

x = 9, NM = 41

Step-by-step explanation:

Since KL = ML  then the triangle is isosceles and LN is a perpendicular bisector, thus

NM = NK , substitute values

7x - 22 = 3x + 14 ( subtract 3x from both sides )

4x - 22 = 14 ( add 22 to both sides )

4x = 36 ( divide both sides by 4 )

x = 9

Thus

NM = 7x - 22 = 7(9) - 22 = 63 - 22 = 41
