A. 25 degrees
B. 30 degrees
C. 35 degrees
D. 40 degrees
Answers
Answer:

What is the value of n when 6n-14=3n+7
Answers
answer: n=7
work:
6n-14=3n+7
6n-14 (+14) = 3n+7 (+14) add 14 to both sides
6n=3n+21
6n(-3n)=3n(-3n)+21 subtract 3 from both sides
3n=21
3n/3= 21/3 divide by 3 on both sides
n=7
Answer: n = 7
Step-by-step explanation; Simplifying
6n + -7 = 14 + 3n
Reorder the terms:
-7 + 6n = 14 + 3n
Solving
-7 + 6n = 14 + 3n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-3n' to each side of the equation.
-7 + 6n + -3n = 14 + 3n + -3n
Combine like terms: 6n + -3n = 3n
-7 + 3n = 14 + 3n + -3n
Combine like terms: 3n + -3n = 0
-7 + 3n = 14 + 0
-7 + 3n = 14
Add '7' to each side of the equation.
-7 + 7 + 3n = 14 + 7
Combine like terms: -7 + 7 = 0
0 + 3n = 14 + 7
3n = 14 + 7
Combine like terms: 14 + 7 = 21
3n = 21
Divide each side by '3'.
n = 7
Simplifying
n = 7

Answer:
Angle O = 72°, Angle M = 18°, Angle N = 90°
Step-by-step explanation:
According to the angle sum theorem, all interior angles of a euclidean triangle always add up to 180°.
given 5(Angle M) = Angle N, and 4(Angle M) = Angle O, you can substitute these equations into the equation defined by this theorem, Angle M + Angle N + Angle O = 180°
. Angle M + 5(Angle M) + 4(Angle M) = 180°
10(Angle M) = 180°.
then you divide. Angle M = 18°
with this statement. you can substitute this into the other equations to get the other answers.
5(18°) = Angle N, 4(18°) = Angle O.
90° = Angle N, 72° = Angle O.
angle O=72, angle M =18, Angle N = 90

Please mark me as the Brainliest.
Step by Step Explanation:
To solve this equation, we do NOT need the same denominator.
And since both fractions are negative, we know the answer is going to be positive.
So we just multiply normally.
-1/4 • -3/7
We cannot cross cancel anything, so we just multiply across.
-1 • -3 = 3
-4 • -7 = 28
So our answer is 3/28.

Given f(x) = 4x − 6 and g(x) = f(2x),
write an equation for g.
g(x) = _______________________
Answers
Answer:
1 and 1/3
Step-by-step explanation:
Fx equals 4x-6
Add six to both sides
6 equals 4X
Divide both sides by 4
2/3 equals x
Then GX equals f (2x)
Two times 2/3 is 1 and 1/3
The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given that f(x) = 4x − 6 and g(x) = f(2x), then;
We have to Add six to both sides;
f(x) = 4x − 6
6 = 4X
Now Divide both sides by 4;
2/3 = x
Then G(X ) is equals to f (2x)
Now, 2( 2/3 ) = 1 /3
The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3

Kara and James both like to mix a little bit of milk with their eggs when they make scrambled eggs. Kara mixes ¾ of a tablespoon of milk with one egg. James mixes 1 ¼ tablespoons milk with two eggs. Is there a proportional relationship between Kara and James’ milk and egg amounts?
Answers
Answer:
"No, there is not a proportional relationship."
Step-by-step explanation:
"A proportional relationship is when 2 amounts have the same ratios.
The easiest way to see this is to put them into decimal form.
3/4 is equal to 0.75 (You can find this by dividing 3 and 4 in the calculator)
1 1/4 is equal to 1.25
Kara mixes every 0.75 with 1 egg.
James mixes every 1.25 tablespoons with 2 eggs.
Divide 1.25 by 2 to find out how many tablespoons that James mixes with 1 egg.
1.25 tablespoons /2 = 0.625
2 eggs /2 = 1 egg
Therefore, James mixes 0.625 tablespoons of milk with 1 egg.
They do not mix the same amount of tablespoons of milk for ever ONE egg, meaning that they are not proportional."
