Combine like terms to simplify the expression below.

12(6x+4)+5x−8

Answers

12 (6x + 4) + 5x -8

First you’d need to distribute the 12 in order to begin combining like terms.

72x + 48 +5x -8

Circle which have an exponent which would be 72x and +5x which would be 77x

Box the numbers without exponents and combine those 48 -8 which equals 40

77x + 40

There is no number that these two share so there is no way for them to be simplified so your answer is just 77x + 40.

12(6x +4) + 5x - 8

Distribute the 12 to the 6x and 4.

72x + 48 + 5x - 8

Combine 72x and 5x since they both have the variable x.

77x + 48 - 8

Combine 48 and 8 because they both have no variable

77x + 40

Answers

Answer:

A = 48 cm²

Step-by-step explanation:

This figure can be thought of as a rectangle 4 cm by 8 cm in the middle and one triangle on the left side and a congruent triangle on the right side. The triangles have 8 cm bas and 2 cm height.

total area = area of rectangle + 2 × area of triangle

total area = (4 cm)(8 cm) + 2 × (8 cm)(2 cm)/2

total area = 48 cm²

The answer is C. Hope this helps.

108 is 36% of what number? Write and solve a proportion to solve the problem.

Answers

First write the proportion to find the missing value, which I will replace it with n.
108/n = 36/100
Next write the cross products. So, 36n = 108 x 100 = 10,800
divide each side by 36.
36n/36 = 10,800/36
Lastly simplify. Which will be, n = 300.
so my answer is 108 is 36% of 300.

This is how I was taught:

1. Take the percentage (36%) and change it to a decimal (.36)

2. Set up the equation.

.36x = 108

3. Divide both sides by .36

x = 300

A pet store specializes in exotic fish. The graph shows a proportional relationship between the number of fish and the number of fish tanks at the store. Fish 65 52 39 26 13 0 1 2 3 4 Fish Tanks 5 6 X The constant of proportionality shown in the graph in terms of the number of fish per fish tank is

Answers

Answer:

Step-by-step explanation:

if there are 5 tanks and 65 fish in all the tanks together, you take 65 and divide it by 5 to get 13 fish in each tank

: )

Answer:

10.84.

Step-by-step explanation:

To find the constant of proportionality, we can use the fact that the relationship between the number of fish and fish tanks is proportional. This means that the ratio of the number of fish to the number of fish tanks is always the same.

From the graph, we can see that when there are 65 fish, there are 5 fish tanks. When there are 52 fish, there are 6 fish tanks. Let's use these two data points to find the constant of proportionality:

The constant of proportionality = (Number of fish) / (Number of fish tanks)

For the first data point, we have:

65 / 5 = 13

For the second data point, we have:

52 / 6 = 8.67

We can see that these two values are not the same, which means that the relationship between the number of fish and the number of fish tanks is not exactly proportional. However, we can still find an average constant of proportionality between these two values:

(13 + 8.67) / 2 = 10.84

So the constant of proportionality, in terms of the number of fish per fish tank, is approximately 10.84.

What is a proportional relationship?

A proportional relationship is defined according to the equation presented as follows:

y = kx.

In which k is the constant of proportionality, representing the increase in the output variable y when the constant variable x is increased by one, thus being also called unit rate.

The unit rate of the graph is given as follows:

k = 20/11

k = 1.82.

For each table, the rate is given as follows:

Table 1: 13/7 = 1.86.Table 2: 9/5 = 1.8.Table 3: 17/9 = 1.89.Table 4: 21/11 > 20/11.Table 5: 19/10 = 1.9.Table 6: 25/13 = 1.92.Table 7: 21/12 = 1.91.

Answer:

Step-by-step explanation:

To find the area of a rectangle, you multiply the length by the height.

First, we need to convert the mixed numbers to improper fractions:

Length: 6 3/4 ft = (6 x 4 + 3) / 4 ft = 27 / 4 ft

Height: 2 2/12 ft = (2 x 12 + 2) / 12 ft = 26 / 12 ft = 13 / 6 ft

Now we can calculate the area:

Area = Length x Height

Area = (27 / 4) ft x (13 / 6) ft

Area = 351 / 24 ft^2

Area = 14 11/24 ft^2

Therefore, the area of the rectangle is 14 11/24 square feet.
