Answer: the number of adult tickets sold is 150
the number of student tickets sold is 210
Step-by-step explanation:
Let x represent the number of adult tickets sold.
Let y represent the number of student tickets sold.
The adult tickets cost $12 each, and the student tickets cost $8 each. The total cost of tickets sold $3,480. This means that
12x + 8y = 3480 - - - - - - - - - -1
The total number of tickets sold is 360. This means that
x + y = 360 - - - - - - - - - -2
Multiplying equation 1 by 1 and equation 2 by 12, it becomes
12x + 8y = 3480
12x + 12y = 4320
Subtracting
-4y = -840
y = -840/-4 = 210
Substituting y = 210 into equation 2, it becomes
x = 360 - y = 360 - 210
x = 150
Answer:
y = -4x - 2
Step-by-step explanation:
This line y= -4x-5 has slope = -4
Parallel line, slope is the same so slope of the new line is also = -4
Passes through the point (-2,6), equation:
y - 6 = -4(x + 2)
y - 6 = -4x - 8
y = -4x - 2
Answer:
y = -4x - 2
100-99=1+98=99-97=2+96=98-95=3
2-1=1
Answer:
<h2><u>STEPS</u></h2>
-
Step I: Obtain the given number.
- Step II: Resolve the given number into prime factors by successive division.
- Step III: Make pairs of prime factors such that both the factors in each pair are equal. Since the number is a perfect square, you will be able to make an exact number of pairs of prime factors.
- Step IV: Take one factor from each pair.
- Step V: Find the product of factors obtained in step IV.
- Step VI: The product obtained in step V is the required square root.
<h2><u>Example </u></h2>
<u>
Find the square root of 324</u>
- 324 = 2 x 162
- = 2 x 2 x 81
- = 2 x 2 x 3 x 27
- = 2 x 2 x 3 x 3 x 9
- = 2 x 2 x 3 x 3 x 3 x 3
- ∴ √324 = √( 2 x 2 x 3 x 3 x 3 x 3 )
- √324 = 2 x 3 x 3
- √324 = 18
