On a gameboard spinner, Rachel won a prize on 8 out of 10 spins. Based on experimental
probability, on how many of the next 15 spins should Rachel expect to win a prize?
prizes

1.  You need to make a proportion

2. Your proportion would be 8 over 10 equals X over 15

3. Your equation would be 10x=15(8)

4. 15x8=125

5. 10x=125

6. you would divide 125 by 10

7. thats your answer

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
