Shirts are 30% off. The original price of one shirt is $12. What is the total
cost, in dollars, of 2 shirts, at the sale price, including a 5% sales tax? *

Answer:

x = 14

Step-by-step explanation:

First, organize your work by showing that lines are similar

Line KV is similar to line RV

Line UV is similar to line LV

etc, etc.

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

Now notice that line KV and line RV have the numbers 9 and 18 accordingly

and notice that it's an x2 difference.

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

Now apply the same thing to line UV and LV and divide 26 by 2

That gets us 13

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

Now plug 13 into the equation (2x - 15)

2x - 15 = 13

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

Now solve for X

2x - 15 = 13

Add 15 to each side

2x − 15 + 15 =13 + 15

2x = 28

Divide both sides by 2

2x / 2 = 28 / 2

x = 14

Answer:

A.

Step-by-step explanation:

Hi there!

By factoring the trinomial, we end with (x-9)(x-4)

However, we aren’t done yet. To find the zeros, set each expression equal to zero, so it looks something like this.

0 = x - 9

0 = x - 4

Using orders of operations, x = 9 and x = 4

Therefore,  A is your answer.

I hope this helps!

Answer:

3, -3, -1/2

Step-by-step explanation:

There is no need to distribute, just set each parenthesis to equal to zero.

p(x)= (x-3)(x+3)(2x+1)

         X-3=0                     x+3=0                      2X+1=0

           +3  +3                     -3  -3                           -1  -1

             X=3                        X=-3                          2x=-1

                                                                                x=-1/2

So your answers are 3, -3, -1/2

Answer:

g(10)=92

Step-by-step explanation:

g(x)=10x-8

To find g(10), substitute x with 10

g(10)=10(10)-8

g(10)=100-8

g(10)=92

Easy!

4 units x 4 is

16

Answer:

Step-by-step explanation:

First, we need to find the hypotenuse, so we need to apply the equation from the Pythagorean Theorem

A^2+B^2=C^2.

We know A^2 and B^2, so we need to substitute that into the equation

2^2+4^2=C^2

so now, simplify.

4+16=C^2

20=C^2

Square root of 20 is about 4.5

so 4.5 is the length of the sides of the square.

4.5x4.5=20.25

Did on Calculator : )

Answer:

Yes these are similar

Step-by-step explanation:

Answer:

x=16

Step-by-step explanation:

1 soccer ball =$12

2 makes $24.

24+16=40

so both coaches spend 8 bucks for 4 cones

Each cone costs $2, and the cost is calculated as follows: 8x = 40 - 2 *p, where p is equal to the cost of a football.

A linear equation is an algebraic equation of the form ax + by +c, is and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given that, Two coaches each buy 1 soccer ball for $12 and 4 cones. Each cone costs the same amount. Together the coaches spend $40.

Let x be the number price of the cone.

Thus each coach spends  = 4x  +12

Thus, in total, they spend = 40

4x  +12 +  4x  +12 = 40

8x = 40 -24

8x = 16

x = 2

Therefore, Each cone costs $2 and the equation for calculating the price of the cone is: 8x = 40 - 2 * the price of a football.

Answer:

35

Step-by-step explanation:

Sum of the first 17th term can be calculated as follows

= a + (n-1)d

a= 11

d= 6

n= 5

11+(5-1)6

= 11+ 4(6)

= 11+24

= 35

Hence the sum of the first 17th term is 35

Answer:

75

Step-by-step explanation:

You will set the equation up as part/whole = percent/100 and when you replace it with your numbers you get 60/x = 80/100 now you cross multiply and do 60*100 = 80 * x and you get 6,000 = 80x now you divide both sides by 80 then you get 75 was the original price
