Answer:
Noah is 17 and Tina is 7.
Why?
Let t represent Tina’s age.
So, 2t + 3 is Noah’s age.
This is your equation;
2t + 3 + t = 24
Now, simplify so t is on one side.
3t = 24 - 3
3t = 21
t = 21/3
t = 7
Tina’s age is 7, and Noah (according to the expression made for him) is 17.
Check:
7 + 17 = 24
1. upwards
2. minimum -5
3. domain : xER range: y > -5
4) 2x^2 + 4x - 3
So, Anna has a markers, Ben has b markers and Cindy has c markers.
We know that a+b+c = m.
And we know also that a = 2b. (<span> twice as many markers as ben has</span>)
(Remember b is the number of Ben markers.)
The equation becomes:
2b+b+c=m.
Solving for c:
Cindy has (m-3b) markers.
Angle 1 and 3 are equals and 2 and 4 are the same
to get the slope of any straight line, we can simply use two points off of it, hmmm say let's use here (2,8) and (4,4)
