Suzie went to a candy shop. The candy shop has a sign that shows the cost of the candies at the shop. The sign is below:
aleksklad [387]

Answer:

$8.50

Step-by-step explanation:

Multiply the cost by the amount of candy she bought, your equation will look like this:

2(0.75) + 3(1) + 5(1.40)

Multiplying everything makes the equation into:

1.5 + 3 + 7

Adding everything makes the total cost 11.50.

Subtract 11.50 from 20, and the answer is 8.50

Find the x-intercept of 2x+2y=2
Nana76 [90]

Answer:

x-intercept: <u>(1,0)</u>

y-intercept: <u>(0,1)</u>

Step-by-step explanation:

Given: Find the x and y intercepts of 2x + 2y = 2

<h2><u>X-intercept</u></h2>

To solve for a x - intercept we have to substitue 0 in for y and solve for x

Lets do it:

2x + 2(0) = 2

2x + 0 = 2

2x = 2

x = 1

Therefore, this means that when y = 0, x = 1 or (1,0)

<h2><u>Y-intercept</u></h2>

To solve for a y - intercept we have to substitue 0 in for x and solve for y

Lets do it:

2(0) + 2y = 2

0 + 2y = 2

2y = 2

y = 1

Therefore, this means that when x = 0, y = 1 or (0,1)

What is the sales tax on a breakfast order that totals $10.50 when tax is 5%
Alecsey [184]
First, you would need to create an equation for this problem. Let x represent the unknown tax. 
\frac{x}{10.50} = \frac{5}{100}

Next, you would cross multiply. 
100x = 52.5

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100. 
x = $0.525

I hope this helps!

If the square of a positive integer is added to 55 times the integer, the result is 336336. find the integer.
kompoz [17]
The square of a positive integer added to 4 times the integer is 437..

x2 + 4x = 437

I chose to do this by completing the square..

x2+4x+4 = 437 + 4
(x+2)2 = 441
Take square root of both sides

x+2 = ±√441
x = -2 ± 21

x = -23 or x = 19
x = 19
