(8-11)*l -11 +7 l =
Solve inside the parentheses
8-11 = -3
Solve inside the absolute value signs

A can contained 5.5 ounces of tuna. Joey used 2.88 ounces of the tuna to make a sandwich. To find the amount of tuna remaining in the can, Joey subtracted as shown below: Is Joey's work correct? Explain how you can tell if his work is correct.
Answers
Answer:
Yes
Step-by-step explanation:
A full can of tuna has a certain amount in it, if a portion is removed from the can it is therefore subtracted from the total amount. This means that Joey's work is correct and the tuna can would have
5.5 oz - 2.88 oz = 2.62 oz
The best way to tell if his work is correct would be to weigh the remaining tuna in the can and see if it matches Joey's answer.

X+2y=2 and -x+y=-5
Answers
Answer:
Solution :
{x,y} = {2/3,2/3}
Step-by-step explanation:
Solve equation [2] for the variable x
[2] 9x = 6
[2] x = 2/3
// Plug this in for variable x in equation [1]
[1] (2/3) + 2y = 2
[1] 2y = 4/3
[1] 6y = 4
// Solve equation [1] for the variable y
[1] 6y = 4
[1] y = 2/3
// By now we know this much :
x = 2/3
y = 2/3
(I dunno if this is what you meant or not..)
Answer: x = 4
y = -1
Step-by-step explanation:
Elimination Method:
In an elimination problem, both equations are aranged in the form of an arithmetic problem. One equation must have an offset of either the x or y of the other equation, so as to eliminate the variable for you to solve for the other one. If a variable doesn't have a negative counterpart, multiply the equation by a number so they can offset each other.
Given:
x + 2y = 2
-x + y = -5
Step 1: Solve for x
To solve for x, we need to eliminate the y by creating an equation where the y can eliminate the other equations y.
-2(-x + y = 5) = 2x - 2y = 10
Now that the y's can cancel each other out, we can combine the equations and solve for x.
x + 2y = 2
2x - 2y = 10
3x = 12
x = 12/3
x = 4
This is the value of x
Step 2: Solve for y
The x's can already cancel each other out, so you can just combine the equations and solve for y.
x + 2y = 2
-x + y = -5
3y = -3
y = -1
This is the value of y
Step 3: Verify
To make sure there weren't any mistakes, you need to check by replacing x and y with they're values. x is 4 and y is -1
Substitute: (4) + 2(-1) = 2
Solve: 4 - 2 = 2
Substitute: -(4) + (-1) = -5
Solve: -4 - 1 = -5
The answers are x = 4 and y = -1

Step-by-step explanation:
move the terms 6x-4=16+2x
collect like terms 6x-2x=16+4
divide both sides 4x=20

Answer:
x = 5
Step-by-step explanation:
6x - 4 = 8( 2 + 1/4x) Distribute
6x - 4 = 16 + 2x
-6x -6x Subtract
-4 = 16 - 4x
-16 -16 Subtract

What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Here, it is given that Three less than four times a number is 17.
Let assume the number be x ,
then 4 times the number will be = 4x
and, 3 less then the number means = 4x-3
which is equals to 17 that is :
4x-3 = 17
Therefore, the equation which describes the statement Three less than four times a number is 17 is 4x-3 = 17

It costs $13 to order a cheese pizza and $2 for each extra topping. Write an equation for the function that gives the total cost y in dollars for ordering a pizza with x extra toppings.
Using the equation from question 5. Complete the table.
Extra Toppings X Total Cost (S) Y: Blank, blank, blank
3
4
5
Answers
Answer:
y = 2x + 13
Step-by-step explanation:
total cost of pizza (y) = price of cheese pizza + price ($2) of each added topping (x)
we can start by looking at y = 13 the total cost (y) of a CHEESE pizza is $13
If you want to ADD additional toppings, you pay $2 for each topping. We know how much each topping is, but we are not sure how many additional toppings we need. So x will represent how many toppings are added. We can multiply $2 times how many toppings to figure out the additional cost of the toppings.
y = 13 + 2x ; remember, function form is y=mx+b so re-write the equation as
y = 2x + 13
I am unsure why the 3, 4, and 5 are listed here, but if the problem is asking you to solve for how much your pizza will cost with 3 toppings, 4 toppings, and 5 toppings, you will need to use substitution to solve for the cost.
y = 2x + 13
y = 2(3) + 13
y = 6 + 13
y = 19
If you order a pizza with three additional toppings, your total cost will be $19.

Answer:
x = 1, y = 6
Step-by-step explanation:
Given the 2 equations
y = x + 5 → (1)
y = 6 → (2)
Since we are given the value of y, that is y = 6 then substituting into (1) gives
6 = x + 5 ( subtract 5 from both sides )
1 = x
Solution is x = 1, y = 6
