Let no be x
algebraic expression =x-5
Step-by-step explanation:
answer
240 standard versions
set up equations
s = number of standard versions
h = number of high quality versions
the total size of all standard versions would be 2.3s since each standard version is 2.3 MB
the total size of all high quality versions would be 4.4h since each standard version is 4.4 MB
add them together to get the total size (2664 MB) of all versions
2664 = 2.3s + 4.4h
since the high quality version was downloaded twice as often as the standard, we can say that
h = 2s
substitute h into equation and solve
2664 = 2.3s + 4.4h
h = 2s
2664 = 2.3s + 4.4(2s)
2664 = 2.3s + 8.8s
2664 = 11.1s
s = 2664/11.1
s = 240
Answer:
Step-by-step explanation:
The master chief has three and a half cookies i.e. 
numbers of cookies.
Again the arbiter has five and three quarters of a cookie i.e. 
number of cookies.
Therefore, in total there are 
numbers of cookies.
If we divide the total number of cookies in to equal parts and distribute to then then each of them will get 
numbers of cookies. (Answer)
Answer: 9 1/3 minutes
First create an equation with the given information; with x being the commercial time, 30=3x+2, now solve for x. First subtract 2 from each side and get 28=3x and then divide each side by 3 to get 9 and 1/3 minutes.
