At a concession stand, a pickle and two bags of chips costs a total of $3.25. Three pickles and four bags of chips costs a total

kolbaska11 [484]

Answer:

A bag of chips costs $1

A pickle costs $1.25

Step-by-step explanation:

P + 2c = 3.25 Start with these two equations

3p + 4c = 7.25

p = -2c + 3.25 Solve for one variable

3(-2c +3.25) + 4c = 7.25 Substitute

-6c + 9.75 + 4c = 7.25

-2c = -2

c = 1

p + 2(1) = 3.25 Substitute

p + 2 = 3.25

p = 1.25

Solving by elimination -6x+6y=6 -6x+3y=-12

labwork [276]

So elimination method is basically adding the equations and canceling out variables.
-6x + 6y = 6
-6x + 3y = -12
The eaiest way to solve is by multiplying the bottom equation by -1.
-6x + 6y = 6
6x - 3y = 12
Now you add the eqautions.
3y = 18
Divde 3 from both sides.
y = 6
Now plug in 6 into any of the original two equations. Lets use the first one.
-6x + 6(6) = 6
-6x + 36 = 6
Subtract 36 from both sides.
-6x = -30
Divide -6 from both sides.
x = 5
So your solution is (5, 6).
I hope this helps love! :)

Which of the expressions below have exactly 3 terms? Select all that apply.

Fynjy0 [20]

Answer:

C. 6x + 9 - 3x^2

Step-by-step explanation:

We have 4 expressions and are being asked which has 3 terms.

When it comes to terms, terms are numbers that are different, it could be separated through a variable, square root, symbol, e.t.c.

So when looking for an answer, we need 3 numbers with different variables or symbols, let's look

A. only has two, 10x and 8. Therefore it is wrong.

B. has 4 terms, 3x^3, 6x^2, 9x, and 12. Therefore it is wrong.

C. is correct because it has 3 terms, 6x, 9, and 3x^2.

D. has 2 terms, 833 and 12x, though 16 is there, it is the same as 833, therefore not counting it as its own term.
