Answer: a
Step-by-step explanation:
1)
y = kx
-12 = k(9)
k = -4/3
y = (-4/3)(-4)
y = 16/3
2)
y = kx
8 = 20k
k = 2/5
y = (2/5)(10)
y = 4
3)
y= kx
-6 = k(-14)
k = 3/7
-4 = (3/7)x
-4(7/3) = x
x = -28/3
With this information we can set up 2 equations:
x + y = 312 (# of tickets sold for adults + # of tickets sold to adults = 312)
12x + 5y = 2204 ( # of tickets sold for adults times $12 + # of tickets sold to adults times $5 = $2204)
Where x is how many tickets were sold to adults and y how many tickets were sold to children
Now we can solve this system of equations by substitution:
isolate y in the first equation to find its value and plug it in the second equation
x + y = 312
isolate y by subtracting x from both sides:
x - x + y = 312
y = 312 - x
Apply y = 312 - x to the second equation
12x + 5y = 2204
12x + 5( 312 - x) = 2204
12x + 1560 - 5x = 2204
7x + 1560 = 2204
Subtract 1560 from both sides to isolate x
7x + 1560 - 1560 = 2204 - 1560
7x = 644
Divide both sides by 7
7/7x = 644/7
x = 92
Now plugin 92 for x in the first equation to find the value of y
x + y = 312
92 + y = 312
subtract 92 from both sides
92 - 92 + y = 312 - 92
y = 220
x = 92, y = 220
92 tickets were sold to adults and 220 tickets were sold to children

<u>Answer:</u>
<em>The correct answer is 1 1/2</em>
<u>Step-by-step explanation:</u>
<em>First, We need to find out the sum of 2/3 x 3, change 3 into a fraction if you want</em>
<em>3x2=6 and 1x3 is 3, So 2/3 x 3 is 6/3 or 2</em>
<em>Next, divide 3 by 2, change to fractions if needed</em>
<em>Remember keep, change and flip, flip 2/3 to 1/2</em>
<em>Then, you multiply 3/1 and 1/2 3x1=3 1x2=2</em>
<em>Finally divide 3 by 2. 3 ÷ 2 is 1 1/2</em>
<em>I hope this helped!</em>
