Answer: B. 1/2 (6x + 12) = 3x + 6
Step-by-step explanation:
= 1/2 (6x + 12)
= 1/2(6x) + 1/2(12)
= 6x/2 + 12/2
= 3x + 6
Answer:
the correct answer is D) 8
Step-by-step explanation:
2 dozen= 24
2/3 of 24 is 16
24-+6=8
therefore, 8 of the cupcakes were chocolate
√x+3 = 2
First we should simplify the equation by squaring both sides:
x + 3 = 4
Isolate x by taking 3 off both sides:
x = 1
We should ALWAYS check that our answer is correct after working out the value of x. We can do this by substituting x into the original equation:
√x + 3 = 2
Turns into:
√1 + 3 = 2
Which turns into:
√4 = 2
Which is true, therefore we can confirm:
x = 1
