Am confused
Pls help

Answer:

A*B*C= 28

Step-by-step explanation:

A+B+C=20

1. A = 4(B+C)

2. B = 7C

3. C = C

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

1.

A = 4( 7C + C )

A=4(8C)

A= 32C

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

A+B+C=20

32C + 7C + C = 20

40C = 20

C = 20/40

C = 1/2

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

A= 32(1/2) = 32/2 = 16

B= 7(1/2) = 7/2

C= 1/2

A*B*C = 16 * 7/2 * 1/2

A*B*C=  28

-9 that is the answer

Answer:

3x - 3 + 5x = 4(2x -3)

collect like terms

3x + 5x - 3 = 8x - 12

8x -3 = 8x - 12

8x -8x = 3 - 12

it's null

the expression is an indefinite one

Step-by-step explanation:

The road around the park = 3 m wide,

and the circumference of the park = 132 m,

We have to find the cost of fencing

the outer boundary,

the rate = $10 per m

Step-by-step explanation:

As we know that the circumference

of a circle = 2 × 22÷7 × radius

2 × 22÷7 × radius = 132 m,

44 × radius = 132 m × 7,

44 × radius = 924 m,

radius = 924 ÷ 44 m

So, radius = 21 m ( smaller circle )

radius = 21 m + 3 m ( larger circle )

= 24 m

Usually, we fence on the borders means it's

the circumference of the larger circle

= 2 × 22÷7 × radius

= 44÷7 × 24 m

= 1056÷7 m

= 150.85 m

cost of fencing = $ 10/m

total cost = 150.85 × $ 10

= $ 1508.57

Step-by-step explanation:

The graph of [tex]y = \frac 34x +5[/tex] has a slope of 3/4 and a y-intercept of 5

The linear equation is given as:

[tex]y = \frac 34x +5[/tex]

Set x = 0

[tex]y = \frac 34 * 0 +5 = 5[/tex]

Set x = 1

[tex]y = \frac 34 * 1 +5 = 5\frac 34[/tex]

Set x = 2

[tex]y = \frac 34 * 2 +5 = 6\frac 12[/tex]

The above means that, the graph of [tex]y = \frac 34x +5[/tex] passes the following points

[tex](x,y) = \{(0,5), (1, 5\frac 34), (2,6\frac 12)\}[/tex]

See attachment for the graph of the linear function [tex]y = \frac 34x +5[/tex]

Answer:

19, 18, 15.5

Step-by-step explanation:

To solve this problem, you need to substitute the given values into the function.

b(x = -2) = 18 - 0.5(-2) = 18 + 1 = 19

b(x = 0) = 18 - 0.5(0) = 18 - 0 = 18

b(x = 5 ) = 18 - 0.5(5) = 18 - 2.5 = 15.5

Answer:

A) 23+x = 35

x = 12

Step-by-step explanation:

The question is asking you to find the equation and variable that best represents the scenario. We know that Emily had 35 dollars and had 7 dollars after paying for everything. This means that 7 plus what she spent must equal 35. However, we only know the cost of the ticket. So, add the cost of the ticket to the money left to figure out part of the equation. This equals 23 dollars. Therefore, whatever is left must be what she spent on lunch. So, the equation should look like 23 + x = 35. This is because the $23 is the ticket/the amount left and the x is the cost of lunch. Together they equal what Emily brought to the fair.

Hello there!

When we are given the graph of a line and two points on the graph, we can calculate the slope of the line using Rise/Run.

Rise=How many units we move up (here, the rise is 3)

Run=How many units we move left or right (Here, the run is 5)

So the slope of this line is [tex]\frac{3}{5}[/tex]

Answer:

D) 22

Step-by-step explanation:

B is the midpoint. The midpoint is the point in a line that breaks the line into two equal segments. With that info, we know that BC = AC.

So that means:

3x - 14 = x + 10

Now solve this equation.

3x - 14 = x + 10

+14. +14

3x = x + 24

-x

2x = 24

/2. /2

X = 12.

Now we know the value of x, insert the value into x + 10.

12 + 10 = 22

The answer is 22

Answer:

B) 12

Step-by-step explanation:

Because,

3x - 14 = x + 10

3x - x = 10 + 14

2x = 24

x = 12
