Answer:
B. Subtract 7
Step-by-step explanation:
You always want to isolate the <em>x</em> term to solve for <em>x</em> in any equation. Therefore, we need to move the 7 to the other side. Only way to do that is to subtract 7 on both sides.
Answer:
4^12
Step-by-step explanation:
4^9 * 4^3
We know that a^b * a^c = a^ (b+c)
4^9 * 4^3
4^(9+3)
4^12
Just plug in 100 for x
2(100)+1
200+1
Answer
201
and then for 25
2x+1=25
2x=24
Answer
X=12
Hey there, we are given quite a lot of information in this problem. First of all, let's make an equation.
y = x - 22
where y = student's age
where x = instructor's age
this equation is correct because x(instructor) - 22 will yield the student's age (y).
If the instructor were 44 years old, the student would be 22 years old.
y = 44 - 22
y = 22
If the instructor were 66 years old, the student would be 44 years old.
y = 66 - 22
y = 44
