Answer:
The correct answer is D. 10.
Step-by-step explanation:
If Brandy earns 2 stars for every goal, and she scored 8 goals, then we need to multiply 8 by 2.
8 x 2 = 16
She looses 1/2 a star for every miss, and she missed the goal 12 times. Therefore, we need to multiply 1/2 by 12.
12 x 1/2 = 6
Therefore, Brandy lost 6 stars.
Now, we need to subtract the amount of stars Brandy earned by the amount that she lost.
16 - 6 = 10
Therefore, the correct answer is D. 10.
Hope this helps! :D
<h3>
There are 2 answers: choice C, choice D</h3>
====================================================
Explanation:
32% = 32/100 = 0.32
32% of 400 = 0.32*400 = 400(0.32), which adds onto the original 400 to get 400+400(0.32). This is why choice D is one of the answers.
We can factor out the GCF 400 to go from 400+400(0.32) to 400(1+0.32) which then simplifies to 400(1.32) or just 400*1.32. This shows choice C is the other answer. Using a calculator,
400+400(0.32) = 400 + 128 = 528
400*1.32 = 528
meaning that 400+400(0.32) = 400*1.32
The other answer choices result in other values, showing that they aren't equivalent to 528.
You keep the same sign. So:-
4 + 4 = 8 and
--4 + -4 = -8
reflexive postulate of equality
