okay so that's an inequality. You solve it the same way you saw the regular equation. the only difference is that if you divide or multiply by a negative number then you have to turn the sign around.

Answer:

57.76 in²

Step-by-step explanation:

Plug in 4.6 as x in the equation and solve:

m(x) = x² + 6x + 9

m(4.6) = (4.6)² + 6(4.6) + 9

m(4.6) = 57.76

So, the area of the mat is 57.76 in²

Step-by-step explanation:

If I is the midpoint of JH, JI= IH

JH= JI +IH

JH= JI +JI (subst. IH= JI)

JH= 2(JI)

Since JI= 79,

JH= 2(79)

JH= 158

Answer:

62.22%

Step-by-step explanation:

First, find how many total marbles there are:

12 + 11 + 17 + 5

= 45

Then, find how many marbles that are not blue:

12 + 11 + 5

= 28

Then, divide 28 by 45, and multiply by 100

(28/45) x 100

= 62.22% is the probability of not choosing a blue marble

Answer:

40 did it on edge

Step-by-step explanation:

The unit rate of calories per ounce will be 40 calories/ ounce

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

We are given that 4-ounce container of Greek yogurt contains 160 calories and it is to calculate for one ounce calories contain in Greek yogurt :

4-ounce = 160

1- ounce = 160/4

=40

Therefore, the unit rate of calories per ounce = 40 calories/ ounce.

Answer:If the number is over 5 then you go to the next number

Step-by-step explananation

7.99 = 8 its over 5

Answer:

b = 36 is the lie.

Step by step:

If we plug in b with it equaling -36 the equation will be

-39 - (-36) which you remove the minus from the -36 and change the subtraction to addition and you get

-39 + 36 = -3

In the end b = -3

So the other one must be wrong, but just incase we will plug it in.

-36 - 36 = 0

Plugging in 36 for b results in 0 which is not correct.

See attachment for the figures drawn for each question.

10. x = 3; AB = 11

11. x = 2; AB = 6

Step-by-step explanation:

10. AC = 10x + 2

AB = 2x + 5

BC = 4x + 9

AB + BC = AC (segment addition postulate)

(2x + 5) + (4x + 9) = 10x + 2 (substitution)

The equation above is what we would use to solve the problem as follows:

2x + 5 + 4x + 9 = 10x + 2

Combine like terms

6x + 14 = 10x + 2

6x - 10x = -14 + 2

-4x = -12

Divide both sides by -4

x = 3

AB = 2x + 5

Plug in the value of x

AB = 2(3) + 5 = 6 + 5

AB = 11

11. AB = 3x

BC = x - 6

AC = 8x - 14

AB + BC = AC (segment addition theorem)

3x + (x - 6) = 8x - 14 (substitution)

Use the equation to solve for x as follows:

3x + x - 6 = 8x - 14

Collect like terms

4x - 6 = 8x - 14

4x - 8x = 6 - 14

-4x = -8

x = 2 (dividing both sides by -4)

AB = 3x

AB = 3(2)

AB = 6

Answer:

A) (3,7)

Step-by-step explanation:

If the value of x goes from -7 to -2, that means to get the coordinate b you have to add 5 again, so the x value of coordinate B is 3. Then, if the value of y goes from 3 to 5 you have to add 2 to the y-value again to get 7. So the y value is 7. Meaning the final answer is (3,7)

Answer:

A) (3,7)

Answer: x - 2y + 2z

keep it in alphabetical order!

Step-by-step explanation:

the negative on the outside changes what is on the inside, so the new equation will be

3x + 4y - 2x + 2z - 6y

combine like terms

x - 2y + 2z

Answer: 3x +10y

Step-by-step explanation:

first you put all the common integers (i think that is what they are called) together

3x+4y+6y-2z-(-2z)

Then you add and subtract all the integers

4y+6y=10y

-2z-(-2z)=0

so the answer is

3x+ 10y

Hopefully this is the right answer

God bless you!!

Answer:

I believe the term is the index number

I assume we're solving for n.

3n/7 - 1 = 1/8.

First, add 1 to both sides.

3n/7 = 9/8

Now, let's multiply both sides by 7

3n = 63/8

Divide both sides by 3

n = 21/8

Answer:

57/99

Step-by-step explanation:

let's set up an equation:

x = 0.5757...

set up a second equation so the numbers after the decimal places are equal

100x = 57.5757...

subtract

100x = 57.5757...

- x = 0.5757

99x = 57

divide by 99

x = 57/99

0.57 repeating can be expressed as the fraction 19/33 in simplest form.

We have,

Let x = 0.575757... (with 57 repeatings)

Multiplying x by 100,

100x = 57.575757...

Subtracting the original x from 100x,

100x - x = 57.575757... - 0.575757...

99x = 57

To obtain x, divide both sides by 99:

x = 57/99

Dividing both the numerator and denominator by 3,

x = (57/3) / (99/3)

x = 19/33

Therefore,

0.57 repeating can be expressed as the fraction 19/33 in simplest form.
