Answer:
B
Step-by-step explanation:
-3/4y - 1/5y = 380 can be simplified to -19/20y = 380.
In order for the student to incorrectly get 361, they likely just multiplied the 380 by 19/20 rather than multiplying by the reciprocal (which would be -20/19).
This means the best answer should be B.

Answer:
The answer is 12
Step-by-step explanation:
First, you do 2+8=10. You do that first becuase it is in the parentheses
After that, You do 15+3=18
Then, 4 and the 2 over it. Which is a exponent. And that tells you to multiple the number by itself. So 4x4=16.
But it also says subtract the 4. So now you Add the 10+18=28
Then you subtract 16 from 28. 28-16=12.
Thats how you get your answer.

What is a right angle triangle?A right angle triangle is a triangle in which one of the three angles is a right angle.
What is the tangent of an angle in a right angle triangle?"In any right angle triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). In a formula, it is written simply as 'tan'."
Given, Base of the right angle triangle is = 12.

Answers
Answer:
15 possible combinations
Step-by-step explanation:
Given
[tex]Vegetables = 6[/tex]
[tex]Selection = 2[/tex]
Required
Determine the possible number of combinations
The question emphasizes on "selection" which means "combination".
So; To answer this question, we apply the following combination formula:
[tex]^nC_r = \frac{n!}{(n-r)r!}[/tex]
In this case:
[tex]n = 6[/tex]
[tex]r = 2[/tex]
The formula becomes:
[tex]^6C_2 = \frac{6!}{(6-2)!2!}[/tex]
[tex]^6C_2 = \frac{6!}{4!2!}[/tex]
[tex]^6C_2 = \frac{6*5*4!}{4!2*1}[/tex]
[tex]^6C_2 = \frac{6*5}{2}[/tex]
[tex]^6C_2 = \frac{30}{2}[/tex]
[tex]^6C_2 = 15[/tex]
Hence, there are 15 possible combinations

June's mother was 29 when June was 5 years old. How old will June be when she is one-quarter her mother's age?
Answers
Given :
June's mother was 29 when June was 5 years old.
To Find :
How old will June be when she is one-quarter her mother's age.
Solution :
Let, age of June when she is one-quarter her mother's age is x and mother's age is y.
So, y = 4x ...1)
Also, we know that difference between two person's age is constant.
So, y - x = 29-5
y - x = 24 ...2)
Solving equation 1 and 2, we get :
[tex]4x -x = 24\\\\3x = 24\\\\x = 8[/tex]
y = 32
Therefore, June will be 8 years old when is one-quarter her mother's age.
