1.) 25 - 3x = 88
2.) -11 = 7 - x
3.) 95 = -4 + 33x​

Answers

Answer 1

Answer: hope this helps ♡

1.) x = -21

2.) x = 18

3.) x = 3

Step-by-step explanation:

(minus&minus = plus)       (minus&plus = minus)        (plus&minus = minus)

1.) 25 - 3x = 88

25 - 25 - 3x = 88 - 25

-3x = 63

-3x ÷ 3 = 63 ÷ 3

-x = 21 → x = -21

2.) -11 = 7 - x

-11 - 7 = 7 -7 -x

-18 = -x

18 = x → x = 18

3.) 95 = -4 + 33x​

95 + 4 = -4 + 4 + 33x

99 = 33x

99 ÷ 33 = 33x ÷ 33

3 = x → x = 3

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:

13

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.

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

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.

How does the fact that the points are on opposite sides of the y axis affect the process of finding the distance between the two points?

Answers

Answer:

See below.

Step-by-step explanation:

The fact that the points are on opposite sides of the y-axis does not affect the process of finding the distance between the two points. The distance between two points in a two-dimensional coordinate system can be found using the distance formula, which is based on the coordinates of the two points and does not depend on which side of the y-axis they lie. The distance formula is:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points, and d is the distance between them. The formula involves squaring the differences between the x-coordinates and the y-coordinates of the two points, and then taking the square root of the sum of the squares. The process remains the same regardless of which side of the y-axis the points are located.
