Answer:
11≤√134≤12
Step-by-step explanation:
11^2 is 121
and 12^2 is 144
so √134 would have to fall between these numbers
So I did this:
y=x +2
y=3x-4
I used the first equation to plug into the second equation.
x+2= 3x -4
I subtracted 3 from both sides so I get
-2x+2=-4
So I subtract 2 from both sides so I get
-2x=-6
I divide -2 on both sides and so I get
x=3
Then I plug the x into either equation. I did the first equation.
y=3+2
y=5
So x=3 and y=5

Answer 180, 260 and 360
Step-by-step explanation
Eli age = 9
Freda age = 13
Geoff age = 18
We write the ages in ratio as 9 : 13 : 18
Now sum all the ages 9 + 13 + 18 = 40
The total amount to be shared is £800
Therefore Eli share = 9/40 x £800 = £180
Freda share = 13/40 x £800 = £260
Geoff share = 18/40 x £800 = £360
