3x + 9 = 90
3x = 90 - 9 = 81
x = 81/3 = 27
x = 27
Answer:
Length = 13 cm
Step-by-step explanation:
Length (L) = 2 x Width (W) + 5
2 x (L + W) = 34
2 x (2W + 5 + W) = 34
6W + 10 = 34
6W = 34-10 = 24
W=4
L = 13
6:45a to 7:45 = 1 hour
7:45 to 8:45 = 2 hours
8:45 to 9:45 = 3 hours
9:45 to 10:45 = 4 hours
10:45 to 11:45 = 5 hours
11:45 to 12:45 = 6 hours
12:45 to 1:45 = 7 hours
1:45 to 2:45 = 8 hours
2:45 to 3:00 = 8 hours and 15 minutes
then just add the 28 minutes to the 15 minutes
28 + 15 = 43
6:45a to 3:28p = 8 hours and 43 minutes.
Hope this helps.
Answer:
sila put a wrong number in her calculator when multiplying the numerators
Step-by-step explanation:
Sila jogged 12 kilometers today and wants to know how far she traveled in feet. what error did sila make while converting from kilometers to feet?
StartFraction 12 kilometers Over 1 EndFraction times StartFraction 0.62 miles Over 1 kilometer EndFraction times StartFraction 5280 feet Over 1 mile EndFraction = 392,832 feet
sila put a wrong number in her calculator when multiplying the numerators.
1 km sila's first fraction should be 0 62 mi 1 mi
sila's last fraction should be 5280 ft
sila forgot to divide by 0 62 asap
(12kilometers / 1 ) × (0.62 miles / 1 kilometer) × 5280 / 1 mile
12 kilometers = 39,370.079 feet
1 kilometer = 0.621 miles
sila put a wrong number in her calculator when multiplying the numerators
How many males and how many females would there be if the total enrollment is 15000?
Ratio is
90 males 15000 - x
------------- = ---------------
125 fem x
Then 90x = 1875000 - 125x, or 215x = 1875000
x = approx 8720 females
and 15000-8720, or 6279 males
If every male finds a dance partner, that would leave (8720-6279) females, or 2440, without dance partners. ;(
Check: is the male:female ratio near 90:125?
Is 6279:8720 approx equal to 90:125?
Yes. 0.72 (approx) = 0.72 (approx).
