Simplify the following fraction by putting it in lowest terms or by performing the indicated operation.

Answer:

×=2

Step-by-step explanation:

7=×+9

×=9-7

×=2

as we were told tht the value of y=7 which means where the is y we subsitude 7

which will give us 7=×+9

The addition of 9 is positive and 7 is positive, then when jumping the equal sign it shall be negative therefore 9-7=2

Answer:

2)

a. x= -84

b. x= 9/4 or 2.25 in decimal form

c. x= 53/5 or 10.6 in decimal form

d. x= 31/2 or 15.5 in decimal form

3)

a. y= -10

b. y= -28

c. y= -114

d. y= 68

Step-by-step explanation:

2) substitute y as 7

a. y= x+91

7=x+91

7-91=x

-84=x

x= -84

——————

b. y= 4x-2

7=4x-2

7+2=4x

9=4x

9/4=x

x=9/4 or 2.25

————————

c. y= 5x-46

7= 5x-46

7+46=5x

53=5x

53/5=x

x=53/5 or 10.6

—————————

d. y= 6x-86

7= 6x-86

7+86=6x

93=6x

93/6=x

31/2=x

x= 31/2 or 15.5

—————————

3) substitute x as 13

a. y= -x+3

y= -13+3

y= -10

——————

b. y= -2x-2

y= -2(13)-2

y= -26-2

y=-28

——————

c. y= -3x-75

y= -3(13)-75

y= -36-75

y= -114

——————

d. y= 8x-36

y= 104-36

y= 68

Answer:  2 x 2 x 2 x 2 x 2 x 5 x 5

Explanation:

We start with the string 2 x 2 x 2 x 2 x 5 x 5

Then we tack on a "2 x" up front, or at the very left, so that we double the result. This is because the jump from 400 to 800 is "times 2".

So we go from 2 x 2 x 2 x 2 x 5 x 5 to 2 x 2 x 2 x 2 x 2 x 5 x 5

We can condense this into [tex]2^5*5^2[/tex]

Answer:

see below

Step-by-step explanation:

In order

4π ≈ 12.57

√150 ≈ 5√6 ≈ 12.25

11 4/9 ≈ 11.44

note: pi is written as "π''

The square root of 40 is a rational number if 40 is a perfect square. It is an irrational number if it is not a perfect square. Since 40 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 40?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.

√40 is an irrational number

Step-by-step explanation:

Answer:

9/8 or 1.125

Step-by-step explanation:

yea simply simplify it

Hey there!

Isolate the variable by dividing each side by factors that don't contain the variable.

Exact Form: n = [tex]\frac{9}{8}[/tex]

Decimal Form: n = 1.125

Mixed Number Form: n = [tex]1 \frac{1}{8}[/tex]

Hope this helps! Have a great day!

Notice that 2/3 times 12 is...

(2/3)*12 = (2/3)*(12/1)

(2/3)*12 = (2*12)/(3*1)

(2/3)*12 = 24/3

(2/3)*12 = 8

So that explains the 8 on the right hand side.

For the blank, we'll multiply 2/3 by the 9y term like so

(2/3)*9y = ((2/3)*(9/1))y

(2/3)*9y = ((2*9)/(3*1))y

(2/3)*9y = (18/3)y

(2/3)*9y = 6y

This means 6y goes in the blank.

If your teacher only cares about the coefficient, aka number out front of the variable, then you'd just go for 6. That's my guess as to what your teacher wants. It seems to fit with the template you show and that would mean R goes in the second to last slot.

Answer:

6)

a. x=35

b. x=4

c. x=30

Step-by-step explanation:

6a) 7/9=x/45

7/9×45=x

7×45/9=x

315/9=x

35=x

x=35

————————

b. 10/8=5/x

5/4=5/x

5/4x=5(the x is in the middle of the division sign here)

5x/4=5(the x is NOT in the middle of the division sign)

5x=5×4

5x=20

x=20/5

x=4

———————

c. x/34=15/17

x=15/17×34

x=15×34/17

x=510/17

x=30

hope that helped you. I can't answer number 7, I'm sorry

Answer:

What question?

Step-by-step explanation:

To solve this equation, you must multiply by a denominator and then subtract to isolate a variable.

Multiply by 4 on both sides of the equation.

[tex]\displaystyle 4(5 + \frac{k}{4}) = 4(3)[/tex]

[tex]\displaystyle 20 + k = 12[/tex]

Subtract 20 from both sides to isolate the k.

[tex]20 - 20 + k = 12 - 20[/tex]

[tex]\boxed{k = -8}[/tex]

The final answer is k = -8.

Answer:

The end point as when we multiply 4.3 x 4.7 we get 20.21 and if there is no end point in distance shown we can assume she displaced 20  meters in 4.7 and that 4.26 seconds had a larger end point.

However a starting and end point is always required.

Step-by-step explanation:

4.7 x 20

Change minutes into seconds (so that the final result would be in meters per second) we do not have to do this as all time is already in seconds.

=  4.7 seconds, Divide the distance by time: velocity = 20/4.7 = 4.25531915

= 4.3 m/s

Answer:

The answer is 8:50 PM.

Step-by-step explanation:

If it's 7:20 PM, then what time is it 90 minutes from now?

Start with 30.  It would be 7:50 PM.  So, add 10 more minutes (with 50 minutes more to add) and you have 8:00 PM.  Add your last 50 minutes.  The time would be, as shown above, 8:50 PM.

Answer:

The answer is "Each glass of lemonade costs 1 1/2 times the cost of orange juice"

Step-by-step explanation:

The easiest way to figure this out is multiple choice elimination.

For the first option to be true the cost of a glass of lemonade would have to be 3.50 each

For the second option to be true orange juice would have to cost more than lemonade which is not the case

If you solve for the price of the orange juice using the third option the price of orange juice you find, $1, is different than the price of orange juice you are given.

That just leaves the fourth option

If you check the fourth option then you find that every time you times one of the values of the price of lemonade you get the corresponding orange juice price in the sequence and therefore the fourth option, bottom right answer, is the correct choice.

Answer:

The answer is Each glass of lemonade costs 1 1/2 times the cost of orange juice
