Answer:

a=15

Step-by-step explanation:

2a-10=20

2a=30

a=15

can i have one brainliest plz

Answer:

a = 15

Step-by-step explanation:

I assumed you were trying to solve for A :)

3a - 10 = a + 20

1. Combine like terms (A's on side, numbers on the other).

3a - 10 = a + 20

-a           -a

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

2a - 10 = 20

     +10   +10

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

2a = 30

Now that all of your like terms are combined, work to isolate A. The only way to do this is to divide by 2 on both sides of the equal sign.

[tex]\frac{2a}{2} = \frac{30}{2}[/tex]

This leaves you with a = 15, which is your answer if you are told to solve for A

I hope this helps!

Answer:

f(x)=9(x+3)^2+2

Step-by-step explanation:

f(x)=9x^2 --> a=9

f(x)=a(x-h)^2+k -->f(x)=9(x-h)^2+k

vertex= (-3,2) --> h=-3 and k=2--> making it f(x)=9(x+3)^2+2

Answer:

x1 = -1, and y1 = -2

Step-by-step explanation:

Step-by-step explanation: The equation of a line in point-slope form. is the equation of the line containing point (x1, y1) and having slope, m. The given point of the perpendicular bisector is (-1, -2), so in this case, x1 = -1, and y1 = -2

One 25 fl oz bottle costs $8

Step-by-step explanation:

144÷18=8

Answer:

8$ if my math is correct.

Step-by-step explanation:

Kind of a trick question. It is asking how much each bottle costs. You know that there are 18 bottles and have a total cost of $144. You  do not need the 25oz for this equation. Lastly, I divided the total cost by 18 to get the total of 8$ for each bottle

Answer:

1. m = -3 b = 2

2. m = 1/2 b = -1

3. m = -1 b = 79

4. m = 2 b = -2

5. y = -4x + 3

Step-by-step explanation:

1. the equation y=mx + b is used in number 1. m = slope and b = y intercept. so, because -3 is in the m spot, it is the slope, and because 2 is in the b spot, it is the y intercept.

2. apply the same concept as number 1. 1/2 is in the m spot, so it is the slope, and -1 is in the b spot, so it is the y intercept

3. To know the slope of the graph, you do rise/run. meaning, from one point on the graph, count how many times you go down to get to the next points, and then how many times you go over to get to the point. So, the slope of this line is -2/2, which is equal to -1. So, m = -1. To get the y intercept, take a pair of points from the graph (for example, (3,76)) and take the slope, and fill those in to the y = mx + b equation, and then solve for b. so, you get 76 = -1(3) + b. then do -1 times 3 and get -3. add 3 to both sides and you get b = 79.

4. apply the same concept on number 4 as you did number 3. Find rise/run, and you get 2/1, so m = 2. then take a point from the line (like point (0,-2)) and and the slope and fill it in to  y = mx + b. you get -2 = -2(0) + b. so, b = -2.

5. simply fill in the information into the y = mx + b equation. remember, m is the slope, and b is the y intercept. so, you get y = -4x + 3

Answer:

The value of the new volume 'x' would be equal to 40.5 cm³.

Step-by-step explanation:

Given

We can determine the volume of the original prism by multiplying the area of the base by the height,

                              volume = (3 cm²)(4 cm) = 12 cm³

Dilation by a factor of 3/2 means that the dimensions of the new prism is 3/2 times that of the original object.

let 'x' be the volume of the new solid,

[tex]\frac{x}{12}=\left(\frac{3}{2}\right)^3[/tex]

[tex]\frac{x}{12}=\frac{27}{8}[/tex]

Multiply both sides by 12

[tex]\frac{12x}{12}=\frac{27\cdot \:12}{8}[/tex]

[tex]x=\frac{81}{2}[/tex]

[tex]x=40.5[/tex] cm³

Therefore, the value of the new volume 'x' would be equal to 40.5 cm³.

Answer:

20%

Step-by-step explanation:

The percentage of students who chose math as their favorite subject 20%

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that there are 450 students at Central Middle School. In a survey, 90 of the student chose math as their favorite subject.

The percentage will be calculated as:-

Percentage = ( 90 / 450 ) x 100

Percentage = 0.2 x 100

Percentage = 20%

The percentage will be 20%.

Answer:

(2,4) is the correct answer

Step-by-step explanation:

In order to solve two inequalities, we have to graph the two inequalities on the graph. We have used the online graphing calculator "Desmos' for this purpose.

When two inequalities are graphed, the area that is common in both inequalities is the solution of the system.

We have to observe the graph to check if given points are in solution set of the system.

In the given points, (2,4) lie in the solution set as indicated in the picture.

Hence,

(2,4) is the correct answer

Answer:

91.

Step-by-step explanation:

The least number will be a multiple of 7 while the number - 1 will be a multiple of 2,3 and 5.

2*3*5 = 30  but 31 is not a multiple of 7.

2*2*3*5 = 60 but 61  is not divisible by 7.

2*3*3*5 = 90 and 91 is divisible by 7.

RULE OF THE GAME:

If 6 spots are marked, a player wins if 4 or more of their spots are among the 6.

QUESTION:

Find the probabilities of having the following numbers of winning spots out of 6.

(A) 6 winning spots

6/6 = 1   In 8 decimal places, 1.00000000

(B) 5 winning spots

5/6 = 0.83333333

(C) 4 winning spots

4/6 = 0.66666667

(D) 3 winning spots

3/6 = 1/2 = 0.50000000
