Combine the terms. Note that: one positive and one negative sign results in a negative sign.

Simplify: 5 + (-4) = 5 - 4 = 1

1 + (-7) = 1 - 7 = -6

-6 + 2 = -4

-4 is your answer

Need an answer for both plez.

Ilya [14]

Answer:

(2, 13)

Step-by-step explanation:

Since they both equal y, you can equal them to each other.

8x - 3 = 2x + 9

Subtract 2x from both sides.

6x - 3 = 9

Add 3 to both sides.

6x = 12

Now divide 6 on both sides.

x = 2

Now that we have found x, we need to find y. Just plug in x to the equations.

y = 2(2) + 9

y = 4 + 9

y = 13

Now, if the next equal has the same y, then both are true.

8(2) -3 = y

16-3=y

13 = y

So therefor, both x and y are true.

Answer:

Step-by-step explanation:

Given is an equation in xy as xy =12

WE are to complete the coordinate table for xy =12

Let us give different values for x and find corresponding values of y

$y=\frac{12}{x}$

Note that x or y cannot equal 0 in this

So let us give other values

x y

Can I have some help?

#1) so if the ratio is 2/3 and the other fraction is 16/?, all you have to do is figure out what it took to get there. For example, if the beginning fraction is 2/3 and the second one is 16/?, we at least know that 2 times 8 is 16, so all we have to do is multiply 3 times 8 to get the bottom number which is 24. So 24 is the amount of tan tiles they will need.

Jerome works as a waiter. He earns $80 each weekend plus 15% in tips on meals served. Jerome served $725 worth of meals last wee

gulaghasi [49]

Answer:

well you would need to look at how much he gets a weekend, and then worry anout the tips.

Step-by-step explanation:

He gets paid $80 each weekend, and a 15% with tips.

you would need to figure out the tips, by taking the $725 and timesing it by .15 for the percent.

which would be 108.75

you would now take 108.75 and add 80 to get what he made that weekend.

108.75+80 = 188.75 dollars
