1 hour = 60 minutes
1 minute = 60 seconds.
Saturn: 10 hours 39 minutes and 24 seconds.
Convert hours to minutes: 10 hours x 60 minutes per hour = 600 minutes.
Convert seconds to minutes: 24 seconds / 60 seconds per minute = 0.4 minutes.
Total time for Saturn : 600 minutes + 39 minutes + 0.4 minutes = 639.4 minutes
2x + By = 15
We solve for y to put the equationj in the y = mx + b form in which b is the y-intercept.
By = -2x + 15
y = -2/Bx + 15/B
The y-intercept is 15/B, and we are told the y-intercept is 5.
15/B = 5
15 = 5B
B = 3
Answer: E. 3
3/2x + 1/5 > = -1 ...multiply everything by common denominator of 10
15x + 2 > = -10
15x > = -10 - 2
15x > = - 12
x > = -12/15
x > = - 4/5 <==
-1/2x - 7/3 > = 5...multiply everything by common denominator of 6
-3x - 14 > = 30
-3x > = 30 + 14
-3x > = 44
x < = -44/3 <==
its gonna be A
16 large candles and 12 small candles were sold.
Step-by-step explanation:
Given,
Worth of candles sold = $144
Total candles sold = 28
Cost of each large candle = $6
Cost of each small candle = $4
Let,
x be the number of large candles sold.
y be the number of small candles sold.
According to given statement;
x+y=28 Eqn 1
6x+4y=144 Eqn 2
Multiplying Eqn 1 by 4
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 2
Putting x=16 in Eqn 1
16 large candles and 12 small candles were sold.
