75% as a fraction in simplest form.

Answer:

2 to the power of six times 3 cubed times seven.

Step-by-step explanation:

The prime factors of 56 are 2 cubed times 7 and the prime factors of 18 are 2 times 3 squared The prime factors of 12 are 2 squared times 3.

A factor is a number that divides another number, leaving no remainder

The highest common factor of 18, 12, and 56 using prime factors is 2.

A factor is a number that divides another number, leaving no remainder

Example: 12 = 4 x 3 where 4 and 3 are the factors of 12.

We have,

18, 12, and 56

The factors of each number are:

18 = 2 x 9, 3 x 6, 18 x 1

So the factors of 18 are 2, 3, 6, 9, and 18.

12 = 2 x 6, 3 x 4, 12 x 1

So the factors of 12 are 2, 3, 4, 6, and 12.

56 = 2 x 28, 4 x 14, 7 x 8, 14 x 4

So the factors of 56 are 2, 4, 7, 8, 14, and 28.

Thus,

The highest common factor of 18, 12, and 56 using prime factors is 2.

Answer:

The above one

The formula should be the same. most likely

Answer:

No, the student did not check the solution to the derived equation in the original equation.

No, a possible solution is a = –2, but it does not check in the original equation because it makes two of the denominators equal to zero.

No, a = –2 is an extraneous solution, and there is no solution to the original rational equation.

Step-by-step explanation:

just did on edge good luck!

The student is wrong in his answer to the equation

3/a + 2 − 6a/2a − 4 = 1/a − 2 is - 2, the correct answer is 2/3.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, 3/a + 2 − 6a/2a − 4 = 1/a − 2.

3/a + 2 - 3 - 4 = 1/a - 2.

3/a - 1/a = 3.

2/a = 3.

a/2 = 1/3.

a = 2/3.

Answer:

117

Step-by-step explanation:

9^2 + 6^2 = 81 + 36

= 117

Answer: 117

Step-by-step explanation: To find the sum of 9² and 6²​, first you’ll have to find the whole number value of both integers (9² and 6²​). Next, in order to do this, multiply 9 x 9 and 6 x 6. (9 x 9 = 81; 6 x 6 = 36). Lastly, add your two sums, being 81 and 36 to give you a final answer or sum of 117.

Step-by-step explanation:

Answer:

4). [tex]y<\frac{1}{2}x-4[/tex] (look at my explanation for how to graph)

5.) [tex]y<\frac{?}{?}x+?[/tex] (look at my explanation for how to get the correct numbers)

6.) [tex]x\geq 2[/tex] (look at my explanation for how to graph)

Step-by-step explanation:

Question 4:

    Solving for y:

First it's better if you solve for y then graph, it's easier that way.

[tex]x-2y>8\\-2y>-x+8\\y<\frac{1}{2}x-4[/tex]

As you might notice the greater than sign flipped, that doesn't always happen. It only happens when you are dividing by a negative number.

    Graphing the inequality:

When you start graphing you should always start by plotting the y-intercept. Which in this case it's [tex](0,-4)[/tex]. Then starting from that point you would go up 1 unit then right 2 units then plot the new point because the slope is [tex]\frac{1}{2}[/tex]. The 1 would be the up and down as for the 2 it will be the right and left. This goes up 1 and right 2 because it's positive. So you keep going creating new points as you go then when you reached the end of the graph you would go back to [tex](0,-4)[/tex] and do the opposite so you will do down 1 then left 2. When you run out of room you will have to draw a line, but be careful the line has to be dotted because the solid lines are used for the greater/less than or equal to signs. Then make sure to add arrows at each side of the dotted line to indicate that this line is infinite.

Question 5:

I'm very sorry but I can't see the picture since it's a bit blurry. So I'll try to explain how to write the inequality the best I can. So first we need to know the y-intercept it should be the point directly on the y-axis. Then find the slope by seeing how it gets to the next perfect point. I can tell you that the slope will be positive. Also for the sign it's dotted that means the sign is [tex]<[/tex]. So the inequality should look something like this [tex]y<\frac{?}{?}x+?[/tex]. Make sure you have the signs correct too don't change the ones I already put in.

Question 6:

For this one the inequality will look like this [tex]x\geq 2[/tex]. Then for the graph you will plot [tex](2,0)[/tex]. Then make a solid line that goes vertically since the only x-value is 3 the y-value will be changing without the x. Then for the shading you will shade the right side of the line.

Answer:

Step-by-step explanation:

15x+5y=8-3x

18x+5y=8⇒eqn 1

15x+5y=20y

15x-15y=0⇒eqn 2

eqn 1 * 3

 54x + 15y=24⇒eqn 3

eqn 3 + eqn 2

69x=24

x=24/69=0.3478

eqn  1⇒

    5y=8-18(24/69)

     y=1.7391/5

     y=0.3478

The solution to the system of equations is (10/3, -2).

Two or more expressions with an equal sign are defined as an equation.

The given equations are 15x + 5y = 20 and y = 8-3x.

15x + 15y = 20

Substitute y = 8-3x into the above equation:

15x + 15(8-3x) = 20

15x + 120 - 45x = 20

45x - 15x = 120 - 20

30x = 100

x = 10/3

Substitute x = 10/3 in y = 8 - 3x:

y = 8 - 3 (10/3)

y = 8 - 10

y = -2

Hence, the solution to the system of equations is (10/3, -2).
