Answer:

8

Step-by-step explanation:

Given that:

Number of white balloon = 24

Number of maroon Ballon = 32

Number of orange Ballon = 16

To obtain the greatest number of arrangements ;

Find the greatest common factor of 24, 16 and 32

Factors of ;

24 = 1, 2, 4, 6, 8, 12, 24

16 = 1, 2, 4, 8, 16

32 = 1, 2, 4, 8, 16, 32

Hence, the greatest factor common to all three is : 8

Hence greatest number of arrangement that can be achieved is 8

Given:

Seven hot dogs and two hamburgers cost 14.50

Two hot dogs and seven hamburgers cost 17.00.

To find:

The cost of one hot dog and the cost of one hamburger.

Solution:

Let the cost of one hot dog be x and the cost of one hamburger be y.

According to the question,

[tex]7x+2y=14.50[/tex]       ...(i)

[tex]2x+7y=17.00[/tex]       ...(ii)

Multiply (i) by 7.

[tex]49x+14y=101.5[/tex]       ...(iii)

Multiply (ii) by 2.

[tex]4x+14y=34.00[/tex]       ...(iv)

Subtract (iv) from (iii).

[tex]49x-4x=101.5-34[/tex]  

[tex]45x=67.5[/tex]  

Divide both sides by 45.

[tex]x=1.5[/tex]  

Put x=1.5 in (i).

[tex]7(1.5)+2y=14.50[/tex]

[tex]10.50+2y=14.50[/tex]

[tex]2y=14.50-10.50[/tex]

[tex]2y=4[/tex]

Divide both sides by 2.

[tex]y=2[/tex]

Therefore, the cost of one hot dog is 1.5 and the cost of one hamburger is 2.

Answer:

the other person is correct

Step-by-step explanation:

i put in the answers and it’s correct

[tex]x^2+10x+22=13\\x^2+10x+22-13=0\\x^2+10x+9=0\\[/tex]

Now completing the square.

[tex](x^2+10x)+9=0\\(x^2+10x+25)+9-25=0\\(x+5)^2-16=0\\(x+5)^2=16[/tex]

(x+5)² = 16 is the rewritten equation... For first question btw.

For the solutions to the equation -

[tex]x+5=\sqrt{16},-\sqrt{16} \\x+5=4,-4\\x=4-5,-4-5\\x=-1,-9[/tex]

x = -1,-9 is the solution, for the second question.

Answer:

10 weeks

Step-by-step explanation:

Let's set an equation for you and your brother.

You have $90 plus $18 for every week you save (x).

90+18x

And your brother has $120 plus $15 dollars per week that he saves (x)

120+15x

You want to have the sum of the money equal so combine the two concluded statements

90+18x=120+15x

Arrange them so that you have like terms on each side

90+18x-15x=12+15x-15x

90+3x=120

90-90+3x=120-90

3x=30

x=10

"x" is our number of weeks you and your brother save so the answer is 10 weeks

Just to be sure you can use our equation and plug 10 for every time you see x to make sure our answer is right.

Step-by-step explanation:

Answer:

MN = 2.8 units

Step-by-step explanation:

By the property of isosceles trapezoid,

1). Bases are parallel.

2). Base angles of an isosceles trapezoid are congruent.

2). Opposite sides of the congruent angles are congruent.

By third property,

Measure of side KL = Measure of side MN

2.8 = Measure of side MN

Another way to find the length of MN is,

Distance between M and N = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

MN = [tex]\sqrt{(3-1)^2+(0+2)^2}[/tex] = [tex]\sqrt{8}[/tex]

MN = 2.8 units

Therefore, MN = 2.8 will be the answer.

Answer:

x = 25/9 or 2.777777778

Step-by-step explanation:

4(2-x) = 5x - 17

8 - 4x = 5x - 17

   +4x   +4x

8 = 9x - 17

+17      +17

25 = 9x

25/9 = x

x = 2.777777778 or 25/9

Answer:

Yvonne should pick mixture B which has a lesser concentration of chili oil.

Step-by-step explanation:

Bob's soup concentration = 18 drops / 4 cups = 9 drops / 2 cups = 4.5 drops/cup

A. 18 / 2 = 9 drops/cup which is a greater concentration

B. 18 / 5 = 3.6 drops/cup which is a lesser concentration

C. 20/ 4 = 5 drops/cup which is a greater concentration

D. 22/ 4 = 5.5 drops/cup which is a greater concentration

Answer:

x = -4

Step-by-step explanation:

1=5(x+1)+16

1=(5)(x)+(5)(1)+16 (Distribute)

1=5x+5+16

1=(5x)+(5+16)(Combine Like Terms)

1=5x+21

5x+21=1

5x+21−21=1−21

5x=−20

5x/5=−20/5

x=−4

Answer:

value of x is -4

Step-by-step explanation:

All you need to do is replace f(x) for 1.

1 = 5(x+1) + 16

backwards solve;

1 = 5x+5 +16

1=5x+21

1-21=5x

-20=5x

x=-4

That's all.

If it asks you if x=1, then just plug in 1 where ever x is. f(x) is symbolic of y.

Answer:

Sale price of a sweat shirt is $15.30 and a soccer ball is $21.08.

Step-by-step explanation:

A). Usual price of a sweat shirt is = $18

Sale price of the sweat-shirt is 85% of the usual price.

Therefore, Sale price = 85% of $18

=

= $15.30

B). Usual price of a soccer ball is = $24.80

Sale price of the soccer ball is 85% of its usual price.

Therefore, Sale price = 85% of $24.80

=

= $21.08

Therefore, sale price of a sweat shirt is $15.30 and a soccer ball is $21.08.

Answer:

(0, 2) or C

Step-by-step explanation:

The solution to the system of linear equations is (0,2). The correct option is C.

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

It is given that in a coordinate grid with 2 lines. The first line labelled f(x) passes through (-3, 3), (0,2), and (3, 1). The second line labelled g(x) passes through the points at (-3, 0) and (0, 2).

Plotting the two lines by using the points on the graph. After plotting the points there will be two lines that will intersect at the point ( 0, 2 ). Then the solution of the equation is ( 0,2).

Therefore, the solution to the system of linear equations is (0,2). The correct option is C.
