Hello! The value of x+y is 12
Make sure to read an explanation so you can understand the solution better.
Any questions about the answer and explanation can be asked through comments.
Step-by-step explanation:
We can simply solve the system of equations by substituting x = 3y in the first equation
[tex] \large{2x + 2y = 24} \\ \large{2(3y) + 2y = 24} \\ \large{6y + 2y = 24} \\ \large{8y = 24} \\ \large{y = 3}[/tex]
Therefore, the value of y is 3. Then we substitute the value of y in x = 3y.
[tex] \large{x = 3y} \\ \large{x = 3(3)} \\ \large{x = 9}[/tex]
Therefore, the value of x is 9.
Since you want to find x+y, simply add 9 and 3 as we get 12.
Therefore x+y = 12.

Answer: 23°
Step-by-step explanation:
First, we need to find the missing angle to the left of x
Let's take what we are given
which is 130°, As you notice the angle of 130° is on a straight line
A straight line is supposed to equal 180°
So we can take 180°-130° which will equal 50°
Now we know that the missing angle next to x is 50°
Now we need to take 107° and add it to 50
Which will equal 157°
Now to get x, we need to take 180°-157°
Which will equal 23°
x=23°

{0.5, 1}
Answers
Answer:
A
Step-by-step explanation:
it can't be any answer with 0, because when you substititue the variable a with 0, it simplifies to 3 ≥ 8 which is false, so C and D are incorrect. it also can't be B since when you substitue a with 1 it simplifies to 6 ≥ 8 which is also false. therefore A is the correct answer, hope this helps :)
Answer:
{2.5, 3}
Step-by-step explanation:
2a + 3 ≥ 8
2a + 3 - 3 ≥ 8 - 3
2a ≥ 5
[tex]\frac{2a}{2}[/tex] ≥ [tex]\frac{5}{2}[/tex]
a ≥ 2.5
From the expression above, a is equal to 2.5 and any number above 2.5
∴The answer is {2.5, 3}
