If the adjusted ratio was 2:7, then
2x is the number of pull-ups
and
7x is the number of box jumps.
You can state that since he completed 63 box jumps at the end of his training, then
7x=63,
x=9
and
2x=18.
The total number of exercises performed is 2x+9x=18+63=81.
As at start the ratio was 5:4, then
5y was the number of pull-ups
and
4y was the number of box jumps.
Therefore, 5y+4y=81,
9y=81,
y=9
and 5y=45, 4y=36.
Answer: Initially: 45 pull-ups and 36 box jumps. At the end: 18 pull-ups and 63 box jumps.
Add all the numbers together and the difference is the answer which is 44%
well, if the expression is simply 12-2, then you would do simple subtraction and your answer would be 10. that would be simplest form. you cannot take it any simpler because there is nothing else left now. your answer would be 10.
Answer:
(a)
A to B to C =40 yards
(b)
w<40
Step-by-step explanation:
We are given
The distance between point A and point B is 15 yards
AB=15 yards
The distance between point B and point C is 25 yards
BC=25 yards
(a)
A to B to C = AB+BC
A to B to C =15+25
A to B to C =40 yards
(b)
direct distance between A to C or AC
It must be less than distance between A to B to C
AC< AB+BC
AC< 15+25
AC< 40 yards
w<40
