Answer:

3s + 7.99 = 71.83

Step-by-step explanation:

Yeah, algebra sure confused me the first time I took it. I had a much more patient and engaging teacher the second time!

How would we find out in real life how much each shirt cost? We'd subtract 7.99 from 71.83 and divide the difference by 3, right??

Let's work that backward. Let's say a shirt cost $6. Three would cost $3(6), or $18. Since each shirt costs $s, our price for 3 shirts is $3s. We have to add shipping to get a total, which we are given. When writing an equation, we leave out labels like $ or meters or books or whatever.

Is this done correctly or incorrectly??<br> PLEASE LET ME KNOW<br><br>PLZ HELP ASAP
Dimas [21]
You're very close. However, the less steep line should go through (4,7) and not some point slightly above that location. Also, the shaded region should be above both dashed lines at the same time. So you won't include the portion that I've marked in blue (see attached). Other than that, it looks great.

C an somebody please tell me what 9+10 is?
Mekhanik [1.2K]

' 9 + 10 ' is a simple exercise in addition.  Its solution is  19 .

There is junk floating around the internet saying that 9+10=21.
That statement is false, and the arithmetic is wrong.
The whole thing is a joke.  If you ask someone to prove it, they will
perform a demonstration with Roman numerals, but the way they handle
the Roman numerals is itself defective, and they're hoping you won't notice.

3x + 5y = 7<br> 4x + 3y = 2<br><br> Both x and y have to be the same numbers!
Black_prince [1.1K]
Simultaneous Equations:
(3x + 5y = 7)×(-3)
(4x + 3y = 2)×(5)

-9x - 15y = -21
20x+15y =10        (-15y and and+15y cancels out)

11x = -11
\frac{11x}{11} = \frac{-11}{11} (11 and 11 cancels out)
x= -1
substitute the x we found into either original expressions

3(-1) + 5y = 7
-3 + 5y = 7
+3 -3+ 5y = 7+ 3
5y = 10
\frac{5y}{5}=\frac{10}{5} (5 and 5 cancels out)
y=2 
Check it!
4(-1)+3(2) = 2
-4 + 6 = 2
2 = 2

3(-1) + 5(2) = 7
-3 + 10 = 7
7 = 7

x= -1
y= 2

Given g(x)=-2x+2, solve for x when g(x)=8.
Ksivusya [100]

Step-by-step explanation:

GiVen

g(x) = 8

Now

g(x) = - 2x + 2

8 = -2x + 2

2x = 2 - 8

2x = -6

x =  \frac{ - 6}{2}

therefore x = -3
