Answer:
The Answer is: Josh hit 47 balls.
Step-by-step explanation:
Let j = Josh number of hits and c = Caiden number of hits:
j = c/2 + 9
Total:
j + c = 123.
Substitute:
(c/2 + 9) + c = 123
c/2 + c = 123 - 9
c/2 + c = 114
1/2c + 2/2c = 114
3/2c = 144
c = 144 (2/3) = 76, Number of hits for Caiden
Solve for j:
j = 76/2 + 9
j = 38 + 9 = 47, number of hits for Josh
Proof:
j + c = 123
47 + 76 = 123
123 = 123
Hope this helps! Have an Awesome Day!! :-)
Answer: B = 1
Step-by-step explanation: The first step is to add 6 to both sides of the equation to get -2b = -2
You then divide both sides by negative 2 so you can get a positive
dividing both sides by negative 2 will leave you with 1b = 1
so
b = 1
They are all pretty easy all you do is multiply the cost by the amount of things you buy. For example number 4 your variables are cost (c) and songs (s). Your equation is c•s so $0.99 • s. 50 songs would be .99 • 50 which is $49.50
Answer:
the answer is b because it justifies why the theory of evolution is a theory not a law.
