Answer:

1) x-3=0

4) 6=2x

6) x²=9

Step-by-step explanation:

x-3=0

x=3

----

1+x = 2

x = 2-1

x = 1

----

9-x=3

9-3=x

6=x

----

6=2x

6/2=x

3=x

----

x/5=3

x=3*5

x=15

----

x²=9

x=±3

These are the value of x solved for each equations. If you have any questions, feel free to ask.

Answer:

Part 2)  5 hr

Part 3)   $80 and $160

Step-by-step explanation:

Part 2)  Equate the two pay equations:  20H = 10H + 50

             Subtract 10H from both sides:  10H = 50

              Then H = 5.  

               After 5 hours, each would have earned the same    amount.

Part 3)  In an 8-hour day, one guy would earn ($20/hr)(8 hr) = $160, and the other guy would earn ($10/hr)(8 hr) = $80.

Answer:

2. 5 hours

3. $80 and $160

Answer:

40 m²

Step-by-step explanation:

Multiply side by side(2 m):

2×4=8 8+8=16

Multiply the perimeter:

8×2=16 4×2=8

add everything:

16+16+8=40

Hope this helps!

Answer:

triangle side = 0.54

so both triangle sides = 1.08

and then the sides (1.5 * 3.5) * 2 = 10.5

the last side = 0.9 * 3.5 = 3.15

so add it all  3.15 + 10.5 +  1.08

total area = 14.73 m^2

Answer:

$8.50, the rate is 9.65%

Step-by-step explanation:

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

Step-by-step explanation:

Answer:

Step-by-step explanation:

x = original length of one side

(x-2)² = 20 inches²

x-2 = ±√20 = ±2√5

x = 2±2√5

2-2√5 is an extraneous solution,

so x = 2±2√5 ≈ 6.47 inches

Answer:

30 books on the shelf are Fiction.

Step-by-step explanation:

Hey!

There are 50 books on a shelf.

how many books on the shelf are Fiction?

==================================================================

MAKE AN EQUATION!

We know that there are three Categories: Fiction, Science Fiction, and Non Fiction.

Total- 50

⇒ 50 =

1/5 of 50 are SF

⇒ 50 = (1/5)(50)

3/10 of 50 are NF

⇒ 50 = (1/5)(50) + (3/10)(50) + x

--------------------------------------------------------------------------------------------------------------

SOLVE THE EQUATION!

(1/5)(50) + (3/10)(50) + x = 50

To Isolate X-

  -Multiply and remove the parentheses..

⇒ 50/10 + 150/10 + x = 50

   -Simplify.

⇒ 5 + 15 + x = 50

   -Add Like Terms

⇒ 20 + x = 50

     -Subtract 20 from both sides.

⇒ 20 + x - 20 = 50 - 20

      -Simplify Right Hand Side.

⇒ x =  30

--------------------------------------------------------------------------------------------------------------

So, 30 books on the shelf are Fiction.
