Answer:
2400 inches or 2000 feet is the correct answer
there are 60 minuets in an hour, and 10 sets of 6 minuets, so you multiply 5 by ten to get 50
then you multiply 50 by 48 to get 2400
then you divide by 12 to get 2000 feet
Answer:
12
Step-by-step explanation:
Since it is on a right angle we can equation the sum of both angles to 90:
6x-2+20 = 90
Now we simplify:
6x+18=90
Now we subtract 18 from both sides:
6x+18-18=90-18
Simplify:
6x=72
Now we divide both sides by 6:
6x÷6=72÷6
Simplify:
x = 12
Answer:
8 hours for math and science each
Step-by-step explanation:
4 x 8 = 32
3 x 8 = 24
32 + 24 = 56 hours
- You need to keep what you multiply, (ex. 8), the same as you work through this problem.
- Such as this problem, sometime the best methods are to just guess and check. This means to think of a number that is reasonable and try it. For example, if you try 5 and you see it is too low, go higher. Keep doing this and you would have got to 8 eventually.
Let the number be x.
(2/3)x = 3 1/2 + (3/8)x
(2/3)x - (3/8)x = 3 1/2
(8*2 - 3*3)/(8*3) x = 7/2
(16 - 9)/24 x = 7/2
(7/24)x = 7/2
7x/24 = 7/2 Divide both sides by 7
x/24 = 1/2
x = 24*1/2
x = 12
The number is 12.
