Joan can't quite read the board in her math class. She writes down the equation she reads on the
board as 3x – 7 = 38. She correctly solves the equation she wrote down, but is surprised to hear the
teacher say the answer is 6 less than the answer she found. When she asks the teacher to check her
work, the teacher says that Joan copied the coefficient of x incorrectly (but copied everything else
correctly). What should the coefficient of x have been?

Answer:

$699.52

Step-by-step explanation:

Theres two ways to solve this.

(1) You can either find 7 percent of 653.76 and then add it on

or

(2) You can just multiply the tax with the 653.76

Option (1)

You find 7 percent of 653.76. Now percent means out of a hundred so 7 percent is really 7/100 or 0.07

Now you multiply 653.76 by 0.07 which is 45.76 (rounded to nearest cent)

Now add it up to the total.

653.76+45.76= $699.52

Option (2)

This is the easier method in my opinion. SInce you want to find the total of the product including tax. The tax is technically multiplying the total. The total of course is 653.76 and total means everything. Everything means 100%. So you can add 100% to the tax cause technically thats what your doing becuase you grinding 7percent of the total which is 100 percent. So in this case your price is increasing by 107 percent.

(Example)

So If you want to find 100 percent of a product it would be the same exact result. Like 100 percent of 653.76 is 654.76… So using that we can just add the amount of tax to the 100%. 100+7=107%

Proof that this works is this

usually when you want to find a percentage of something, you turn the percentage into a decimal then multiply. So 100 percent of 653.76 is 653.76*1.00 which is 653.76. So the 100 percent is a place holder to prevent you from doing more steps. Now just add 7 percent since your increasing the total by 7 percent (tax). Now its 653.76*1.07 which when solved you would get $699.52. The same exact result. Less steps same result.

Final answer: $699.52

Answer:

[tex]\frac{9x}{2}[/tex] - 16

Step-by-step explanation:

8.5x - 2(2x + 8)

Use the distributive property to multiply −2 by 2x+8.

8.5x - 4x - 16

Combine 8.5x and −4x to get 4.5x.

4.5x - 16

= [tex]\frac{9x}{2}[/tex] - 16

Answer:

If we make our connecting flight then our plane is not late.

Step-by-step explanation:

The contrapositive occurs when the conclusion and the hypothesis change places.   Let the hypothesis be represented by "p" and the conclusion be represented by "q".  

                                                        hypothesis (p)                 [ conclusion (q)]

Now in the given statement:  If (our plane is not late), then [we make our connecting flight].

statement            If p then q

contrapositive  If q then p

The required contrapositive statement is: "If we do not make our connecting flight, then our plane is late."

The contrapositive of the statement "If our plane is not late, then we make our connecting flight" is formed by negating the hypothesis (antecedent) and the conclusion (consequent) and then switching their positions. The contrapositive is logically equivalent to the original statement. Here's the contrapositive:

Original Statement: If our plane is not late, then we make our connecting flight.

Contrapositive: If we do not make our connecting flight, then our plane is late.

In the contrapositive, we negate the "our plane is not late" to "our plane is late" and negate "we make our connecting flight" to "we do not make our connecting flight." Then we switch their positions.

1 hours = 60 min

60 x 9/10 = 54 min

3 divided by 54 = 1/18

so she walks 1/18 miles per hour.

Im not sure though. It might be 3 divided by 9/10 = 3 1/3. I’m not that confident in my answer. But it is definitely one of them, either 1/18 or 3 1/3.

y = - 0.5x + 2.5

y = -1/2 + 5/2

Step-by-step explanation:

2x -4y = 10  lets find y

-4y = 10+2x

-4y = 2x-10

-4y/-4 = 2x/-4 - 10/-4

y = - 0.5x + 2.5

how to approach answering questions for hw and for exam

step 1 hw  find a diagram   exam rewrite the diagram

step 2 hw work out each multiple question

step 3 see below how workings should be

SIGMA TELLS US     The nth term is  = k

SIGMA TELLS US      The bottom value is value we start with    _vs

SIGMA TELLS US      The top value is the term we end with      - te

A     n-2  turns into 9  which makes  7n-5    become -2+7-5 = 0  

B     n-12  turns into 12 which makes 7n-5 become -1 +7- 5 = 1   (12 x7=84 and -5+84 = 79)

we can prove by using nth common term 7 x 12 -5 = 79

C     n -1   turns into 5 which becomes -1+7 = 6

D     n- 1 turns into 5 which becomes -1+7-5 = 1

we see the sequence given is 2, 9, 16 ....79  it is ascending sequence +7

we know the nth term is 7n-5 as we work out first step ( 2 - 7= -5)

we see the term we end with is either 9 12 or 5 and we see the end term given value is 72 so B is our answer.

Answer:

7.5

Step-by-step explanation:

To find the area of a trapezoid it is:

[tex]A= \frac{a+b}{2}h[/tex]

Where h is the height, b is the base, and a is the "top base," so our values are:

h = 5

b = 9

a = 6

Plug them in and solve:

[tex]A= \frac{a+b}{2}h[/tex]

[tex]A= \frac{6+9}{2}5[/tex]

[tex]A= \frac{15}{2}5[/tex]

[tex]A = (7.5)(5)[/tex]

[tex]A = 37.5[/tex]

The area of the rectangle is found by using:

[tex]A=bh[/tex] where b is the base and h is the height. So our values are:

b = 6

h = 5

Plug in and solve:

[tex]A=bh[/tex]

[tex]A=(6)(5)[/tex]

[tex]A = 30[/tex]

Subtract the rectangle from the trapezoid:

37.5 - 30 = 7.5

Answer: 7.5
