Which is the best estimate for 6,193 ÷ 48 using compatible numbers.
A. 100
B. 120
C. 150
D. 160

Answers

It would be B. 120 you would usually round up but the closest one to 129.02083 is 130 and since there is no 130 it would be 120

The best estimate for 6,193 ÷ 48 using compatible numbers is 120. Therefore, option B is the correct answer.

Given that, 6,193 ÷ 48.

What is the division?

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Here, the number 6,193 can be rounded off to 6000 and the number 48 can be rounded off to 50.

So, 6,193 ÷ 48

= 6000 ÷ 50

= 120

The best estimate for 6,193 ÷ 48 using compatible numbers is 120. Therefore, option B is the correct answer.

Use the table to answer the questions.

X Y Point
-8 8 L
0 4 M
4 2 N
8 0 P

Calculate the slope between point L and point M using the change in y and the change in x. Show all work in the formula. slope =m =

2) Calculate the slope between point N and point P using the change in y and the change in x. Show all work in the formula. slope =m =

3) Write the letter and ordered pair of the y-intercept.

Answers

Answer:

See below for answers

Step-by-step explanation:

1) Slope is Rise/Run=(y2-y1)/(x2-x1)=(4-8)/(0-(-8))=(-4/8)=-1/2, therefore m=-1/2

2) Slope is Rise/Run=(y2-y1)/(x2-x1)=(0-2)/(8-4)=-2/4=-1/2, therefore m=-1/2

3) The y-intercept is point M because the y-intercept of a function is where the graph will cross the y-axis which also means the y-value when x=0. Therefore, the y-intercept is point M which is (0,4)

1. M=-1/2

2. M=-1/2

3. The y-intercept is point M which is (0,4)

Pls help me out, I need to know what value of x makes this equation true

equation: 6(2x – 11) + 15 = 3x + 12

I have already found the answer to this equation (x = 7) but I need to know what value of x makes the equation true.

(If it's 7, my brain just needs a break from stuff, I've been up since 4 in the morning)

Answers

Answer:

x = 7

Step-by-step explanation:

12x - 66 + 15 = 3x +12

12x - 51 = 3x + 12

9x = 63

x = 7

6(2x-11)+15=3x+12
12x-11+15=3x+12
9x=9

X=1

The answer is that x is equal to 1

Answer:

1/2

Step-by-step explanation:

We do change in y over change in x

Formula for Rate of Change on Slope

y2-y1/x2-x1

For Y

We use coordinate (-2, -4)

-4--2

= -2 - -4

= 2

For X

We use coordinate (0, -4)

0 -- 4

= 0 + 4

= 4

Now we put y over x to find the rate of change in slope

2/4, simplified would be 1/2
