Price of bottled water - $3.50 each
price of bag of trail mix - $4 each
number of bottles of water sold - x
number of bags of trail mix sold - y
cost spent for bottles - 3.5x
cost spent for bags - 4y
total cost;
3.5x + 4y = 1475 ----> 1)
total number of items
x + y = 400---2)
multiply 2nd equation by 4
4x + 4y = 1600 ---> 3)
Subtract third equation from the 1st
0.5x = 125
x = 250
when x = 250
x + y = 400
250 + y = 400
y = 150
number of bottles - 250
number of bags - 150
Answer:448
Step-by-step explanation:
So to start,you can see that 8 times 2 is 16.And 16 times 4 is 64.So the pattern is times 2 then times 4 then times 6.On the edges you can see 64.You multiply 64 by 6 and you get 384.Then you multiply 8 times 6 that equals 48.And you multiply 4 times 4 and get 16.After you add 384 and 48 which equals 432.And then your done.(I think that's the answer)

Answer:
Hilda needs 64 ft² of tile
8601 in² will be uncovered post mounting
Step-by-step explanation:
Ar=10•6=60 ft²
At=[4•2]/2=8/2=4 ft²
total area=Ar+At=60+4=64ft²
......
Atv=31•57=1767 in²
Aw=(12•8)•(9•12)=10368 in²
Au=Aw-Atv=10368-1767=8601 in²
Answer:
32

Step-by-step explanation:
Here is the full question :
Arthur is organising his collection of DVDs He has 112 altogether. The ratio of comedy films to action to horror is 4 : 7 : 3
How many of each type of DVD does he have?
the number of each dvd arthur has = ratio / sum of ratios) x total number of DVDs
Sum of ratios = 4 + 7 + 3 = 14
Comedy films = (4/14) x 112 = 32
Action = (7/14) x 112 = 56
Horror = (3/14) x 112 = 24
