Answer:
7 7/20
Step-by-step explanation:
4 3/5 - -3 3/4
4 3/5 + 3 3/4
4 12/20 + 3 15/20
7 7/20
There are 66 people because using the ratio 2:1 we know there are twice as many boys as girls and then we can figure out that that 22 more is the same as twice as many which makes there 22 girls and 44 boys
Answer:
a movie, m is 3
a video game, v is 5.5
Brainliest would be really appreciated. (need it to unlock chat)
Feel free to ask further questions if you feel like it.
Till then, have a nice day
Step-by-step explanation:
I 5m+2v=26
II 3m+8v=53
I 5m+2v=26 devide by 2 on both sides
5/2m+v=13 subtract 5/2m om both sides
v=13-5/2m
Now put this whole thing in the other equation II, replacing the v there
3m+8(13-5/2m)=53 just calculate it
3m+104-20m=53
-17m+104=53 subtract 53 on both sides
-17m+51=0 add 17m on both sides
51=17m devide by 17
3=m
we found m, v is easy
now put m in an equation from the start, let's take equation I here
I 5m+2v=26
5*(3)+2v=26
15+2v=26 subtract 15 on both sides
2v = 11 devide by 2
v = 5.5
So we found m and v, prices for single items. we can proof this when we put m and v into a given equation and the if it equals a true value
m & v in II
II 3m+8v=53
3*(3)+8*(5.5)=53
9+44=53
53=53
Seems legit.
Assuming that you are talking about a rectangular prism and assuming the two sides are 4x5 inches than its as simple as 4x5x6
4x5=20(base)
20x6=120 cubic inches is ur answer
Answer:
x<7/2
Step-by-step explanation:
5+8x<3(2x+4)
5+8x<6x+12
8x-6x<12-5
2x<7
x<7/2
