With what in regard? For fractions, percentage is relative to the amount “full”. Think or a bottle of water, if it’s 50% full, it’s got 1/2 (50/100) filled with water. Simplifying is the process of taking a big fraction, say, 12/36, and finding the similarity to reduce it. 12 and 36 are both even, so let’s try to divide it by 2. 12/2 is 6, and 36/2 is 18. 6/18. However this is simplified it is not in simplest form, so we can divide It again. 6/2 is 3, and 18/2 9. 3/9 can be reduced by 3, making 1/3. 1/3 is the simplest form.
Step-by-step explanation:
Average speed (S) = 200 m/s
Time taken (t) = 2 .5 hours = 2.5 *60*60 = 9000 sec
Now distance travelled (d) = ?
We know
The distance travelled by a body per unit time is
speed so
S = d / t
200 = d / 9000
d = 9000 * 200
d = 1800000 meters.
The plane flies 1800000 meters.
Step-by-step explanation:
x = 7
3 + 4x = 5x - 4
3 + 4(7) = 5(7) - 4
3 + 28 = 35 - 4
31 = 31
Option C
Answer:
The following are the answers:
a = 1
b = 6
c = -55
Step-by-step explanation:
When looking for a, b, and c in a quadratic, you are looking at coefficients only. The coefficient of x^2, which in this case is 1, is a. The coefficient of x, which in this case is 6, is b. Lastly, the constant at the end, which in this case is -55, is c.
A) x * 7 = y
B) y + 7 +1 = 9x
A) x = y / 7
Substituting this into B)
B) y + 8 = 9(y/7)
Multiplying both sides by 7
B) 7y + 56 = 9y
2 y = 56
y = 28
x = 4
***************************************************
Double Check
4 * 7 = 28 + 7 = 35
9*x = 36
