Answer:

12a

12a = 96

Step-by-step explanation:

12a + (6a + 8) + (10a - 4) + (6a + 8) = 204

Combine like terms.

34a + 12 = 284

34a + 12 - 12 = 284 - 12

34a = 272

34a ÷ 34 = 272 ÷ 34

a = 8

Let's replace a and see.

6a + 8

6(8) + 8

48 + 8

Answer:

its c

Step-by-step explanation:

Answer:

Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.

Hence, option C is true.

Step-by-step explanation:

Function 1

A horizontal straight line is drawn joining the ordered pairs (0, 3) and (4, 3).

Given the points

(0, 3)

(4, 3)

It means

at x = 0, y = 3

at x = 4, y = 3

Since the y-values are same, it means the points lie on a horizontal.

The rate of change or slope of a horizontal line is zero because it does not rise vertically ( i.e. y₁ - y₂ = 0).

Therefore, the rate of change of function 1 = 0

Function 2

y = 3x+1

comparing with the slope-intercept form

y = mx+b      

here m is the rate of change or slope and b is the y-intercept

so the rate of change of the function 2 = m = 3

Conclusion:

The rate of change of function 1 = 0

The rate of change of the function 2 = 3

Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.

Hence, option C is true.

Answer:

4(x-1)+9=17

Step-by-step explanation:

3(-2x+1) + 5 = 3x-4-5x

expand

-6x + 3 + 5 = 3x-4-5x

-6x + 8 = -2x - 4

add 2x to both sides to put all x values + coefficients on one side

-4x + 8 = -4

subtract 8 from both sides to isolate x and its coefficient

-4x = -12

divide both sides by -4 to isolate x

x = 3

plug x=3 into each option to see if it works

1. 5(3+3)-4 = 30-4 = 26 != 10

2. 2(3+1) = 8 != 4

3. 4(3-1)+9 = 17 = 17

4. 4(3)+7 = 19 != 3+8 = 11

Answer:

61 in²

Step-by-step explanation:

Area 2 circles =

2( πr²)

1.5 x 1.5 = 2.25

2.25 x 3.14 = 7.065

7.065 x 2 = 14.130

Area rectangle =

circumference circle x 5 =

2πr = 2(1.5 x 3.14) = 9.42

9.42 x 5 = 47.1

Total Surface Area = 47.1 + 14.130 = 61.230 ≈ 61 in²

Answer:

I did this before and if I remember correctly I'm pretty sure it was C.

Here is the way you would go about these questions. I will complete questions 1 and 3, as well as 7. Seeing the way these questions are solved, I am confident you can complete the rest.

1. The image is telling us that the circle's radius is 3 inches. To find the perimeter using radius, multiply the radius by two to get the full diameter. Then, multiply by π (3.14 in your case).

3 x 2 = 6 inches (diameter= 6 inches)

c=πd

c= 3.14 x 6

c=18.84 inches

∴The circumference is 18.84 inches.

3. The image is telling us that the diameter is 8 feet.

c=πd

c=3.14 x 8

c=25.12 feet.

∴The circumference of the circle is 25.12 feet.

7. This image is a semi-circle, which means that you may find the full diameter and divide by 2 (for half of the full circle).

c=πd

c=3.14 x 23

c=72.22 cm

72.22 ÷ 2= 36.11

∴The circumference 36.11 cm.

Answer:

81

Step-by-step explanation:

62+37=99

180-99=81

Answer:

31 degrees

Step-by-step explanation:

We know that if the angle P is equal to 121+x=180 because when it is reflected, they both have to add up to 180. Therefore, P is equal to 59 degrees. We know that angle L is 90 degrees because there is a square. Therefore, we have to do 180-59-90 to find angle PML. 180-149. Angle PML is equal to 31 degrees.

Answer:

(6,4) is the answer

The coordinates of the plane to represent the locations of his school and bank are (2, 4) and (6, 4).

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

Mark want to add the location of the library on the coordinate plane.

Since, The coordinates of the plane to represent the locations of his school and bank.

Hence, We get;

Coordinate for school = (2, 4)

Coordinate for bank = (6, 4)

Thus, The coordinates of the plane to represent the locations of his school and bank are (2, 4) and (6, 4).

If its correct please mark me as brainliest

Answer: Let j be the cost of each juice bottle.

The total cost of the juice bottles is 4j. The total cost of the oranges and juice bottles is $6.75.

Thus, the equation that represents the given information is: 4j + $2.71 = $6.75. Subtract $2.71 from both sides to get: 4j = $4.04. Divide both sides by 4 to get: j = $1.01.

Therefore, each juice bottle costs $1.01.

Step-by-step explanation:

Total cost = cost of a bag of oranges + cost of 4-pack juice bottles

$6.75=  $2.71 + (4 x jj)

$6.75 = $2.71 + 4jj

take similar terms: $6.75 - $2.71 = 4jj

Add similar terms: $4.04 = 4jj

Divide both sides of the equation by 4: jj =  $4.04 / 4=

jj = $1.01

Answer:

A = B + 52

Step-by-step explanation:

A is the total amount each week. 52 is the initial amount that she earns each week. Then, B represents the amount of books she sells. So, 15 books can be represented by

A = 15 + 52 = 67

Answer:

$67 earnings

Step-by-step explanation:

1.    Let A = $ earned for books sold

2.   Let B = # of books sold

3.   Let A = money earned

4.   Equation:  A =  52 + 1B

5.   Solution:  $67 = 52+ 1(15)
