Answer:
R=(F/3-4)/2
Step-by-step explanation:
Father = F
Joe = J
Alexa = A
R= Rocky
F=3J
A+4=J
A=2R
F/3=J
A=J-4
A=F/3-4
2R=F/3-4
R=(F/3-4)/2
Hope this helps!
First of all, we need to find the slope of the given line, writing it in the 
form and reading the 
coefficient:
So, the slope is 
If a line with slope 
is perpendicular to a line with slope , the following relationship holds:
So, the slope of our line must satisfy
So, we need the equation of a line with slope 1 and passing through (4,7). Given the slope and a point 
of a given line, its equation is given by
So, if you plug your values, you have
Answer is 80cm because you do length x width x height and get the answer
Answer:
18:5???
Step-by-step explanation:
1 1/2hrs = 90 mins
90 / 5 = 18
25 / 5 = 5
I'd say: 18 : 5??
Answer:
120/99 is the answer.
Step-by-step explanation:
It has a line over it means that after the point there are infinite numbers of 21.
•Multiply 1.212121... with 100
we get 121.212121...
•Subtract it with the original one
121.212121.. - 1.212121... = 120.000.. = 120
Write it as an equation :-
Let the fraction be x.
(100×x) - x = 120
100x-x = 120
or, 99x = 120
so, x = 120/99
