Answer:
each friend will get 22
Step-by-step explanation:
so you have 176 you divide that by half and you get 88 so then you divide the other 88 by 4 and you get 22 so Reggie kept 88 and all 4 friends each get 22
Answer:
- 16/5
Step-by-step explanation:
We have point with coordinates (-6, y) which lies ( or belong) on the graph of the straight line 5y=2x-4
When we replace x= -6 in given equation we get 5y = 2·(-6)-4 => 5y= -12-4 =>
5y= - 16 => y= - 16/5
Good luck!!!
We just look at where the curve cuts the x axis.
Taking each stroke as 1 unit.
The solution to the graph is, x = -3, or 5.
It's useful in following conditions:
(i) when you want to know the valency to male compounds
for example :
when H2 and O2 react in normal conditions they form H2O, amd here we needed crossmultiplication of their valencies.
(ii) To know masses while calculating mass number.
For example In case you wanna find mass of 100 molecules of H2O.
(iii) To find electronegativity (to determine type of bond formed).
For example: which kind of bond Hydrogen and Clorine will form.
