−2 1/4=r−4/5 What is r?

Mathematics
1 answer:
dmitriy555 [2]4 years ago
4 0

Answer:

r = -29/20 or r = -1.45

Step-by-step explanation:

I believe you are saying that the equation is -2 1/4 = r - 4/5. If so, then I would solve it in this way:

-2 1/4 = r - 4/5

-9/4 = r - 4/5

-9/4 (20) = r (20) - 4/5 (20)

-45 = 20r - 16

20r = -29

r = -29/20

r = -1.45

Check:

-2 1/4 = r - 4/5

-9/4 = r - 4/5

-2.25 = r - 0.8

-2.25 = -1.45 - 0.8

-2.25 = -2.25

-9/4 = -9/4

Solve the inequality and graph the solution<br> v − 6≥4
Viktor [21]

Answer:

v\geq10

Step-by-step explanation:

v-6\geq4

Solving inequality for v

Adding 6 to both sides.

v-6+6\geq4+6

v\geq10

In order to graph v\geq10 we represent v on the y-axis as it represents the solution.

So the graph would be for y\geq10. So, this would be a line parallel to x-axis and the inequality tells us that the area above the line including the line(≥ the equal in the inequality includes the line) is the solution.

What is theoretical probability of rolling a number greater than 4 on a standard number cube
sergeinik [125]
So cube faces were numbered 1, 2, 3, 4, 5 and 6.

There are 6 faces in total and there are two faces greater than 4 (face 5 and 6).

So that would be (desired outcomes) / (total outcomes) = 2 / 6 = 1/3

So theoretical probability of rolling a number greater than 4 is 1/3.

Hope this helps.

This table shows a linear relationship. x 5 6 7 8 9 y 33 39 45 51 57 Based on the information in this table, which equation can
mr_godi [17]

Answer:

  • B. y = 6x + 3

Step-by-step explanation:

<u>Given</u>

  • x = {5, 6, 7, 8, 9} and
  • y = {33, 39, 45, 51, 57}

<u>The equation in slope- intercept form:</u>

  • y = mx + b

<u>Using two pairs of coordinates (5, 33), (6, 39), we will find the slope:</u>

  • m = (39 - 33)/(6 - 5) = 6/1 = 6

<u>Using one point (5, 33) to find the y-intercept:</u>

  • 33 = 6*5 + b ⇒ b = 33 - 30 ⇒ b = 3

<u>The equation is:</u>

  • y = 6x + 3

Correct option is B
