The answer is 25 children and 75 adults. Equation 1: A+C= 100 and equation 2: 2c+3a= 275
25(2)=50 75(3)=225.
225+50=275
Also 75+25=100
Are you supposed to solve for the equations?
Answer:
A = 54.8 - (1200/x) - 2x
Step-by-step explanation:
Given <em>x</em> the wide and <em>y</em> the height, we have
x*y = 50
⇒ y = 50/x
The area of the printed region is A = w*h
where
Wide: w = (x-2*1.2) = x-2.4
Height: h= (y-2*1) = y-2
then
A = (x-2.4)(y-2) = xy - 2.4y - 2x + 4.8 = 50 - 24*(50/x) - 2x + 4.8
⇒ A = 54.8 - (1200/x) - 2x

Answer:
129 points
Step-by-step explanation:
Let L and C represent the scores of Luke and Caleb, respectively.
L = 2C -15 . . . . . Luke scored 15 less than twice the number Caleb did
L +C = 201 . . . . . they scored 201 points altogether
Add twice the second equation to the first:
2(L +C) + (L) = 2(201) + (2C -15)
3L +2C = 387 +2C . . . . simplify
3L = 387 . . . . . . . . . . . . .subtract 2C
L = 387/3 = 129 . . . . . . .divide by 3
Luke scored 129 points.
