Answer:
x=11, y=1 or (11, 1)
Step-by-step explanation:
I used substitution to solve this. Basically wherever there's an x, I would fill it in as 12-y.
2(12-y)+3y=29
24+2y+3y=29
24+5y=29
subtract 24 from both sides
5y=5
divide by 5
y=1
Now substitute y back in to get x.
x=12-1
x=11
You can also graph this into desmos, and wherever they intercept, that's your answer. I hope this helps!

Theresa volunteers at a food sheif. when she started, there were 213 oranges. After filling X bags of three oranges each, there were fewer than 51 oranges left. How many bags of oranges did Theresa fill?
Write an expression in terms of X for the number of oranges that Theresa bagged.
Part B: Write an expression in terms of X for the number of oranges that are left (have yet to be bagged).
Part C: Write an inequality using the expression from Part B to represent this scenario.
Part D: Solve the inequality for the variable X. Use opposite operations on both sides of the inequality until you get X on one side of the inequality by itself.
Part E: Did you have to flip the inequality sign? Explain why or why not.
Part F: What does the result from Part D tell you about Theresa's situation? Does the answer make sense? Explain.
Part G: Think about graphing the inequality you found in Part D on a number line. What would it look like?
Choose the correct number:
1. open circle on 54 and arrow pointing right
2. open circle on 54 and arrow pointing left
3. closed circle on 54 in arrow pointing right
4. closed circle on 54 and arrow pointing left
Answer:
A- The expression 3x represents the number of oranges that she bagged
B- 213 − 3x (or -3x + 213)
C- 213 − 3x < 51 (or -3x + 213 < 51)
D- x >54
E-Yes, I had to flip the inequality sign because I divided both sides of the inequality by a negative number (-3).
F- x > 54 means Theresa filled more than 54 bags of oranges. It makes sense because if Theresa made more than 54 bags of 3 oranges each, there would be fewer than 51 oranges left over.
G- Number 1 is correct.

Use this expression to name each item. 7m3 + 6r2 – 3r - 8
Answer:
In the given expression [tex]7m^3 + 6r^2 - 3r - 8[/tex]
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8
Step-by-step explanation:
We are given the expression [tex]7m^3 + 6r^2 - 3r - 8[/tex]
We need to give variable, coefficients and constant.
Variable: The value of variable may change. It can be represented by x, y or any other letter
Coefficients: A numerical or constant quality that is placed with the variable. For example in 4x, 4 is coefficient
Constant: It is fixed value. It cannot be changed.
So, in the given expression [tex]7m^3 + 6r^2 - 3r - 8[/tex]
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8

Use the substitution method to solve the system of equations.
2x + 3y = 12
y = x-1
A. (3, 4)
B. (0,4)
C. (3,2)
D. (2,3)
Answer:
(3,2)
Step-by-step explanation:
The solution to the system of equations is (3, 2). So, the answer is option C. (3,2).
How to solve the equations by substitution method?We are given the system of equations:
2x + 3y = 12
y = x-1
We can use the substitution method by substituting the expression for y in the first equation with the value of y from the second equation:
2x + 3(x-1) = 12
Simplifying the equation, we get:
2x + 3x - 3 = 12
5x = 15
x = 3
Now, we can substitute the value of x in either of the two equations to find the value of y:
y = x-1
y = 3-1
y = 2
Therefore, the solution to the system of equations is (3, 2). So, the answer is option C. (3,2).

Answer:
50×5=250m
Step-by-step explanation:
he traveled 250 m
Answer:
250 miles
Step-by-step explanation:
If a car travels 50 miles per hour then we are given 5 hours as a time, we can multiply the two numbers together to get 250 miles. Let's see what the distance is after every hour:
1 hour: 50 miles
2 hour: 100 miles
3 hours: 150 miles
4 hours: 200 miles
5 hours: 250 miles
It is seen that after 5 hours a car driving 50mph would travel 250 miles!
