Hi there!

This gets pretty easy once you understand how to do these kinds of problems. Let's look at the words in the question.

Adison earned 25$. We can push that to the side.
She loaned her friend 18$, which means she took some money away from her first part of it.

25 - 18 = 7$. Now she has 7$ left. (A calculator would be useful to answer these!)

Now, let's put the 7 to the side and check out the rest of the equation. Looks like Adison's grandmother gave her 50 more dollars, and we know that more means to add.

50 + 7 = 57$.

Now, the final part of the question says she ended up with 86$ because she had money before she earned more. To see how much money she had originally, we can subtract 86 from 57.

86 - 57 = 29$.

We now understand that Adison originally had 29$ before earning anymore money.

Hope this helps!

In the equation left parenthesis x squared plus 14 x right parenthesis plus left parenthesis y squared minus 18 y right parenthe

Phoenix [80]

Answer:

Complete the square on x by adding 49 to both sides.

Complete the square on y by adding 81 to both sides.

Step-by-step explanation:

We have been given an equation $(x^2+14x)+(y^2+18y)=5$ . We are asked to complete the squares for both x and y.

We know to complete a square, we add the half the square of coefficient of x or y term.

Upon looking at our given equation, we can see that coefficient of x is 14 and coefficient of y is 18.

$(\frac{14}{2})^2=7^2=49$

$(\frac{18}{2})^2=9^2=81$

Now, we will add 49 to complete the x term square and 81 to complete y term square on both sides of our given equation as:

$(x^2+14x+49)+(y^2+18y+81)=5+49+81$

Applying the perfect square formula $a^2+2ab+b^2=(a+b)^2$ , we will get:

$(x+7)^2+(y+9)^2=135$

Therefore, We can complete the square on x by adding 49 to both sides and the square on y by adding 81 to both sides.

1. Solve for y 4x + 2y = 6

xenn [34]

Answer:

y = -2x + 3

Step-by-step explanation:

4x + 2y = 6

⇔ 2y = $\frac{6 - 4x}{2} = \frac{6}{2} - \frac{4x}{2} = 3 - 2x = -2x + 3$

gina pasted 3 stickers in a book. if she added one sticker to her collection every day, what equation represents the relationshi

lukranit [14]

Answer:

The answer to your question is

Number of stickers = number of days + 3

Step-by-step explanation:

- To find the equation of the line that represents the situation, first, find the slope.

Slope = m = $\frac{y2 - y1}{x2 - x1}$

m = $\frac{4 - 3}{1 - 0} = \frac{1}{1} = 1$

- Find the equation of the line

y - y1 = m(x - x1)

y - 4 = 1(x - 1)

y - 4 = x - 1

y = x - 1 + 4

y = x + 3

y = number of stickers

x = days

Number of stickers = number of days + 3

What does it mean if a check was skipped on a bank statement?

hoa [83]

The correct answer is:

The check has not been cashed yet.

Explanation:

When you receive your bank statements, all of the transactions that have been processed are listed. This includes deposits, debits and checks.

All transactions are usually listed in order of the date of transaction. Additionally, the checks are usually listed at the bottom of the statement.

If there is a gap between check numbers that you have written, it means that the missing checks have not been processed. This means that they have not been cashed or deposited.
