Answer:
y=1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6=2(y+2)
6=(2)(y)+(2)(2)(Distribute)
6=2y+4
Step 2: Flip the equation.
2y+4=6
Step 3: Subtract 4 from both sides.
2y+4−4=6−4
2y=2
Step 4: Divide both sides by 2.
2y/2 2/2
<u><em>Answer:</em></u>
Number of child tickets sold that day = 25 tickets
<u><em>Explanation:</em></u>
Assume that the number of the adult ticket is x and that the number of the child ticket is y.
<u>We are given that:</u>
1- four times as many adult tickets as child tickets were sold. <u>This means that:</u>
adult tickets = 4 * child tickets
x = 4y ....................> equation I
2- Child ticket costs $5.5, adult ticket costs $9.1 and total sales was $1047.5.
<u>This means that:</u>
x(9.1) + y(5.5) = 1047.5
9.1x + 5.5y = 1047.5 ..................> equation II
<u>Substitute with equation II in equation I and solve for y as follows:</u>
9.1x + 5.5y = 1047.5
9.1(4y) + 5.5y = 1047.5
36.4y + 5.5y = 1047.5
41.9y = 1047.5
y = 25
<u>Based on the above calculations:</u>
number of child tickets = y = 25 tickets
number of adult tickets = x = 4y = 4(25) = 100 tickets

<span> by putting values from periodic tabl H2(2 x 1.007947 g H/mol ) + S(32.0655 g S/mol) + 04(4 x 15.99943 g O/mol) =
98.0791 g H2SO4/mol is the answer hope it helps</span>
