Answer 2

Answer: I'm afraid that this is a weak attempt at your math teachers trying to teach you variables. Pretend that each shape is the letter x. Let's solve the first one together. 2x-1=5. To find what x=, you need to work backwards. Instead of subtracting one, add one. 5+1 is 6. Now you have 2x=6. Since x is being multiplied by 2, you need to divide 6 by 2. 6/2 is 3. x=3.
For the next one, we know that the triangle, or x, is 3. Again, let's make a different letter for the square. Let's make the square be y. Now your problem is 3 + y = 1. Once again, let's reverse our thinking to solve for what y=. 1-3 is -2. y=-2. See how that works? Now we need to Solve for the last one. The triangle, which we named x and is 3, and the square, which we named y and is -2, can be plugged into the final equation. 3-2(-2)=z. -2 * -2 is 4, and 3 + 4 is 7. Your final answer is 7.

Zoe paid 18.60 in sales tax and tips for dinner. The sales tax is 11% and she tipped 20%. What was the price of Zoe’s dinner before sales tax and tip?

Answers

Answer:

$60 was the price of Zoe's dinner, before sales tax and tip.

Step-by-step explanation:

Sales tax = 11% * original price = 0.11 * x= 0.11x
Tips for dinner = 20% * original price = 0.20 * x = 0.2x
0.11x + 0.2x = 18.60
0.31x = 18.60
x = 60
$60 was the price of Zoe's dinner, before sales tax and tip.

Answer:

$60 was the price of Zoe's dinner, before sales tax and tip.

Step-by-step explanation:

1. Sales tax = 11% times original price = 0.11 times x= 0.11x

2. Tips for dinner = 20% times original price = 0.20 times x = 0.2x

3. 0.11x + 0.2x = 18.60

4. 0.31x = 18.60

5. x = 60

6. $60 was the price of Zoe's dinner, before everything else

Provide an appropriate response.39) Find a set of 7 scores that has the same mean but a smaller standard deviation than the
set {65, 71, 77, 80, 82, 90, 96}.

Answers

You don't even have to look up the definition of 'standard deviation'. You only
have to remember that 'smaller standard deviation' means 'less spread-out'.

First, let's find the mean (average). It's not supposed to change:

1/7th of (65 + 71 + 77 + 80 + 82 + 90 + 96) = 561/7 = 80 and 1/7 .

Now, just pick 7 scores that total 561 and are all bunched up.

The easiest way would be 80, 80, 80, 80, 80, 80, 81 .
But that's so easy that it feels like cheating.

Let's say 77, 78, 79, 80, 81, 82, and 84 .

Put the following equation of a line into slope-intercept form, simplifying all fractions.2x+2y=18

Answers

Answer:

y = - x + 9

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given the line with equation

2x + 2y = 18 ( subtract 2x from both sides )

2y = - 2x + 18 ( divide through by 2 )

$(2)/(2)$ y = $(-2)/(2)$ x + $(18)/(2)$ , that is

y = - x + 9 ← in slope- intercept form
