Answer:
x = 198
Step-by-step explanation:
1/2x + 101 = 200.
Subtract 101 from both sides.
1/2x = 99
You want x by itself, therefore you have to get rid of 1/2. The opposite of diving by two, is multiplying by two.. therefore, you must multiply both sides by two.
x=99*2
x=198
Answer:
33 ¹/₃ seconds
Step-by-step explanation:
Since the dog is 30 - 24 = <em>6 m/s faster than the cat</em>, that means that the dog is <em>6 meters closer to the cat each second</em>.
So, that gap will close in 200/6 = 33 ¹/₃ seconds.
Ok well first of all let's calculate how many cartons there are of each size:
There are 264 cartons in total and 1/6 of these are small, 2/3 are medium and the rest are large, thus:
Number of small cartons = (1/6)*264 = 44
Number of medium cartons = (2/3)*264 = 176
Number of large cartons = 264 - (44 + 176)
= 264 - 220
= 44
Now we can calculate how many eggs are needed to fill each type of carton:
Each small carton holds 8 eggs, thus the number of eggs needed equals:
8*44 = 352 eggs
Each medium carton holds 12 eggs, thus the number of eggs needed equals:
12*176 = 2112 eggs
Each large carton holds 18 eggs, thus the number of eggs needed equals:
18*44 = 792 eggs
Thus the total number of eggs needed = 352 + 2112 + 792 = 3256
Answer:
10x
Step-by-step explanation:
<h3>Expression:</h3>
Length = x unit
Width = 4*x = 4x
Perimeter = 2*(length + width )
= 2*(x + 4x)
= 2 *5x
= 10x
