Answer:
Are you supposed to change decimals to fractions and fractions to decimals?
If yes,
0.5 = 1/2
11/4 = 2.75
0.25 = 1/4
3/8 = 0.375
Hi!
<h3>We need to isolate b on one side. </h3>
<em>Multiply by 4 on both sides. </em>
-83 * 4 = b/4 * 4
<u>-332 = b</u>
<h2>The answer is b = -332</h2>
<em>To check your answer, put in the value of b. </em>
-83 = -332/4
-83 = -83
<u>This equation is correct. </u>
Hope this helps! :)

Answer: price of soda (a) = $2 and price of popcorn (b) = $0.5
Step-by-step explanation:
Let's denote soda = a and popcorn = b
Kaylin bought a soda and two popcorn, writing out an equation for this would be
a + 2b = $3...........equation (i)
And her brother bought 3 sodas and 1 popcorn.
3a + b = $6.50..........equation (ii)
From equation (i),
a + 2b = 3
Making a the subject of formula,
a = 3 - 2b......equation (iii)
Using substitution reaction, put equation (iii) into equation (ii)
3(3 - 2b) + b = $6.50
9 - 6b + b = 6.50
9 - 5b = 6.50
Collecting like terms,
5b = 9 - 6.50
Divide both sides by 5,
b = 5.
Put b = 5 into equation (i)
a + 2(0.5) = 3
a + 1 = 3
a = 2
Therefore, the price of soda is $2 per one and $0.5 for each popcorn.
