Answer:
The number of seniors who scored above 96% is 1.
Step-by-step explanation:
Consider the provided information.
Two percent of all seniors in a class of 50 have scored above 96% on an ext exam.
Now we need to find the number of seniors who scored above 96%
For this we need to find the two percent of 50.
2% of 50 can be calculated as:
Hence, the number of seniors who scored above 96% is 1.
-3y-8x+3x²
7y-10y= -3y
2x-10x=-8x
Answer:
The expression has two variables x and y.
Step-by-step explanation:
<u>What is a variable?</u>
A variable is a letter, for instance or , that represents an unknown number.
Given the expression
The given expression has three terms which are x, 4y, and -9.
Here:
- The term 'x' is the unknown variable x.
- The term '4y' has a coefficient (the number next to a variable y) of 4.
- The term '-6' is a constant.
As we already know that a variable is a letter, for instance x or y, that represents an unknown number. In other words, the values of x, or y are unknown to us.
Thus, the expression has two variables x and y.
Answer:
answer is x=3 and y=10

Forgot to isolate y and x and simplify
Answer:
2x
Step-by-step explanation:
7x= 7*x
5x=5*x
Subtract.
7-5=2
2*x=2x
So 2x is the answer.
