Let give Poppy = P, Felix = F, Alexi = A
so P+ F + A = 700 ----(1)
P = 2F ----(2)
A = 25 + P ---(3)
we will think in term of P
from (2) F = P/2
from (1) P + F + A = 700
P + P/2 + 25 + P = 700 ---(4)
(4) multiplied by 2
2P + P + 50 + 2P = 1400
5P + 50 = 1400
5P = 1350
so P = 270
so Poppy sold 270 tickets
Felix sold 135 tickets
and Alexi sold 295 tickets //

Answer:
Square root property
Step-by-step explanation:
The given equation is :
We need to write the most appropriated technique to solve the above equation.
Subtracting both sides of the above equation by 6 such that,
Now taking square root on both sides we get :
The square root property is used here, such that the value of x is :
Answer:
11.25
77.85
Step-by-step explanation:
1.6x + 3 = 21
use inverse operation (+ = -, x = ÷) by taking 3 to the opposite side and changing it's integer to negative
1.6x = 21 - 3
divide 2 sides by 1.6
1.6x = 18
1.6x/1.6 = 18/1.6
x = 11.25//
2.15(x-5)=75
inverse operation
x= 75 - 2.15 + 5
x= 77.85//
