Answer:

C)  y = 10/3x - 5

Step-by-step explanation:

Slope intercept equation is y = mx + b:

    m is the slope

    b is y-intercept

When you read slope you can also read it as rise over run. Rise is move up or down on the y axis depending if number is negative or positive. Run is move left or right on x axis depending if number is negative or positive.

Example: y = [tex]\frac{10}{3} x - 5[/tex]

Start at the y-intercept which is -5. On graph you can see the line crosses the y axis at (0, -5). From this point rise 10 then run 3 you'll end up at point (3, 5). Connect the dots of the two points and you'll see a line like the one in the problem.

−12 + 9x = 9x + −12

9x − 12 = 9x − 12

9x − 12 − 9x = 9x − 12 − 9x

1-  A.  3(10÷2) +2·7

2- A.  0.4

3- B.  -2.8

4- C.  n·6 - 12 = 60

Step-by-step explanation:

Heres the work in case teachers ask:

1. The given expression evaluates to ...

30÷2 + 2·7 = 15 + 14 = 29

A: 3(10÷2) + 2·7 = 3·5 + 2·7 = 15 + 14 = 29 . . . . . this will make it true

B: 30÷(6+2)·7 = (30/8)·7 = 210/8 = 26 1/4 . . . . . . ≠ 29

C: 3(10)÷(2+2)·7 = 30/4·7 = 210/4 = 52 1/2 . . . . . ≠ 29

D: (5+2)·7 = 7·7 = 49 . . . . . . . . . . . . . . . . . . . . . . . ≠ 29

2. You can divide the equation by 10 to find the appropriate value of x.

4/10 = 10x/10 = x . . . . . 4/10 matches choice A

3. The expression simplifies to ...

7.5 -10.3 = -2.8 . . . . . . matches choice B

4. "The product of a number and 6" is n×6. Twelve less is n×6 - 12. When that "is 60", the equation can be written ...

n×6 - 12 = 60 . . . . . . . . matches selection C

For each problem, explain or show your reasoning, a. 160 is what percentage of 40? b. 40 is 160% of what number? c. What number is 40% of 1602​

Answers

Answer:

A. 160 Out of 40 is 400%./// B. The answer is 25/// C.  The answer is 3905%

Step-by-step explanation:

( A )  One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 160 is 40% of =  160 X 100     = 400

                                        40

                                             

( B ) The same thing as A but the numbers are switched

       One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 40 is 160% of = 40 × 100      = 25

                                          160

( C ) Working out a percentage increase or decrease between two numbers is pretty simple. The resulting number (the second input) is 1602 and what we need to do first is subtract the old number, 40, from it:

1602 - 40 = 1562

Once we've done that we need to divide the result, 1562, by the original number, 40. We do this because we need to compare the difference between the new number and the original:

1562      = 39.05          

40

We now have our answer in decimal format. How do we get this into percentage format? Multiply 39.05 by 100?

39.05 x 100 = 3905%

160 is percentage of 40,  40 is 160% , number is 40% of 1602​ are 64 , 64 and 640.8 respectively.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Problem A,

40% of 160 = 160 x 40 / 100

                  = 64

Problem B,

160% of 40 = 160 x 40 / 100

                  = 64

Problem C,

40% of 1602 = 1602 x 40 / 100

                     = 640.8

Therefore, 160 is percentage of 40,  40 is 160% , number is 40% of 1602​ are 64 , 64 and 640.8 respectively.

Anyone can help me with this problem

Answers

Answer:

R=50 degrees

Step-by-step explanation:

All of the angle measures together are 180 degrees. You need to make an equation in order to solve this problem:

180= (3x+5) + (11x-1) + (5x+5)

You then combine like terms:

180= (3x+11x+5x) + (5-1+5)

180= 19x+9

Then, subtract 9 from 180:

171= 19x

Then, divide 171 by 19:

9= x

Finally, you plug the value of x into the equation representing angle R:
