Answer: X = 5

Step-by-step explanation:

The correct formula to solve the problem is:

11x - 8 = 47

First, add 8 to each side.

11x = 55

Solve it by dividing both sides by 11:

X = 5

Answer:

-9 11/15

2. 11/24

34/45

4. -5.05

5. -0.622

Step-by-step explanation:

1. -2 4/5 - 6 2/15

convert them to a common denominator and an improper fraction:

-2 4/5= 18/5=- 54/15 -6 2/15= 92/ 15

*15 is the other denominator, so you keep the numbers in the second number the same*

subtract: -54/15- 92/15

since you are subtracting a negative number it goes farther away from zero

-146/15 or -9 11/15

2. -5/12 + 7/8

convert them to a common denominator

-5/12=- 20/48 7/8= 35/40

add: -20/48+35/40

11/24

since you are adding a negative number it goes closer to zero or past zero:

3. 3 3/5 x 2/9

convert 3 3/5 to an improper fraction: 18/5

mulitply the two denominators and the two numerators

17/5 x 2/9= 34/45

This is also the simplest form.

4. Convert to a decimal. -5 1/20

keep the -5 beacuse that is a whole number

divide 1/20 to turn it to a decimal to get 0.05

5. Which number is the largest? -0.65, -0.622, -5/8

to find this you would have to convert all numbers to either a decimal or a fraction.

5/8 is 0.625

the one closest to zero is the largest which is -0.622

-.At a fair hamburgers sell for $3.00 each and hot dogs sell for $1.50 each. The equation 3x + 1.5y = 30 describes the number of

NikAS [45]

Answer:

Part a) The y-intercept is the point (0,20) and the x-intercept is the point (10,0)

The graph in the attached figure

Part b) See the procedure

Step-by-step explanation:

The questions are

Part a) Find the intercepts and graph the function

Part b) What does each intercept represent?

Part a) Find the intercepts and graph the function

Let

x-----> the number of hamburgers

y ----> the number of hot dogs

we have

$3x+1.5y=30$

Remember that

The y-intercept is the value of y when the value of x is equal to zero

For x=0

$3(0)+1.5y=30$

$1.5y=30$

$y=20\ hot\ dogs$

The y-intercept is the point (0,20)

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$3x+1.5(0)=30$

$3x=30$

$x=10\ hamburgers$

The x-intercept is the point (10,0)

Plot the intercepts and graph the line

see the attached figure

Part b) What does each intercept represent?

The x-intercept is the number of hamburgers they can buy if they buy no hot dogs

The y-intercept is the number of hot dogs they can buy if they buy no hamburgers

What is the rate of change of the function represented by the table?

Alexeev081 [22]

Rate of change, or slope, or rise over run, or ‘m’ is the difference between a pair of y-coordinates over the difference between a pair of x-coordinates.

The formula for rate of change or slope is:

m=(y2-y1) / (x2-x1)

All we have to do is take two pairs of coordinates from the table and solve for the slope (m).

Let’s just choose the first two coordinates: (1, 5) and (2, 5).

m=(5-5) / (2-1)

m=(0)/(1)

m=0

So, the rate of change is 0; there is no rate of change. There is 0 rise per 1 unit of run.

Pls help me i need help with this

anastassius [24]

Answer:

Step-by-step explanation:

A "zero" of a function is an input value that makes the function value equal zero. On the graph these input values are -3 and 1; you can see that the function values are zero in both cases. C is correct.
