Answer:
The answer is t/3=20
The right diagram is the one that has the orange boxes with 20s and has a t on top
Answer:
a. p = n + m
where: n is the number of pens, and m is the number of pencils
b. p = 71
Step-by-step explanation:
Let the number of pens and pencils that Alex has be represented by n and m respectively.
But,
number of pens, n = 14
number of pencils, m = 57
Then,
total number of pens and pencils, p = number of pens + number of pencils
i.e p = n + m
p = 14 + 57
p = 71
The total number of pens and pencils that Alex has is 71.

The given set of equations:
y=-3x+1............(1)
y=2x-4 .............(2)
can be solved most conveniently by rewriting as
y =-3x+1 = 2x-4
We concentrate on the right equality, which is expressed in x only:
-3x+1 = 2x-4
Transpose and solve for x
1+4 = 2x+3x
5x=5
x=5/5=1
Substitute x=1 in the
first equation: y=-3(1)+1=-2
second equation: y=2*x-4=2(1)-4=-2
So the solution is x=1, y=-2, or (1,-2)
