Answer:
a = -14
Step-by-step explanation:
a-2/3=-4. Multiply -4 by 3 to get rid of the denominator. This leaves you with a-2 = -12. Move the -2 to the other side to get a = -2-12, which simplifies to a = -14.

Answer:
x = 3 and x = 11
Step-by-step explanation:
To find the app price (x) that will result in 0 annual profit, we just need to make P(x) = 0 and then find the value of x:
P(x) = -2*(x-3)*(x-11)
0 = -2*(x-3)*(x-11)
(x-3)*(x-11) = 0
To make this equation equal to zero, we just need to have (x-3) = 0 or (x-11) = 0
So, the values that give P(x) = 0 are:
(x-3) = 0 -> x = 3
and
(x-11) = 0 -> x = 11
Answer:
75kg
Step-by-step explanation:
Decrease =25÷100×100kg
= 0.25×100kg
= 25kg
Decrease 100kg by 25%=100kg-25kg
= 75kg
3x+y=-5
12x+5y=27
Let y =-5-3x
Insert y into equ.2
12x+5(-5-3x)=27
12x-25-15x=27 den rearrange
-3x=2 den x =-2/3
Den put xinto equ 1
3(-2/3)+y=5
-2+y=5(collect like terms)
Y =7
