Hi! I'm happy to help!
To solve for this, we need to understand what a ratio is. A ratio is a comparison between two things. (in numbers) In this case, between pools and hours:
pools:hours
A fraction is also a ratio, in this case we have 2/5, which also compares pools to hours, so we can turn this into a more proper ratio form:
2 pools: 5 hours
2:5
<u>So, our ratio of pools to hours is 2:5.</u>
I hope this was helpful, keep learning! :D
Answer:
2.8÷4
Step-by-step explanation:
if 2.8 is the 4th lap, you have to divide it by 4 to get the 1st lap.
Equation 1 for tickets sold:
$35x + $25y = $10,250
Equation 2 for quantity (number #) of tickets sold:
x + y = 350
Use substitution method:
y = 350 - x
35x + 25 (350 - x) = $10,250
35x + $8750 - 25x = $10,250
10x + $8750 = $10,250
- $8,750 -$8,750
10x = 1,500
x = 150
y = 350 - 150
y = 200
Check the answers:
$35 (150) + $25 (200) =
$5,250 + $5,000 = $10,250
Answer:
x = 11, ∠ 2 = 146°
Step-by-step explanation:
∠ 2 and 146° are corresponding angles and are congruent, then
∠ 2 = 146°
Thus
13x + 3 = 146 ( subtract 3 from both sides )
13x = 143 ( divide both sides by 13 )
x = 11
The answer is 85.5
