Well, let's look at the answer choices.
A) If you want to fond the total cost of two sweaters you would add, not divide. So this isn't it.
B) To find out how much older someone is you would subtract. So this isn't it either.
C) To find out how many desks are needed you would multiply, since you know you need 3 rows of desks with 7 students each (3 x 7). Again, not it.
D) To find out how many pencils each student would get, you'd divide. You would divide 56 by 9. So your answer is D.
On both sides of the equal sign you subtract b (-b) which would give you -b+y=2x after that you subtract a y (-y) which gives you -b=2x-y now I was taught that you can't have a negative letter equal something so you change all of the signs to the opposite which would give you b=-2x+y
13.6 is the answer because .6 is a 10th value while .60 is a 100 value because it has two digits hence two zeros in 100. And therefore 10 having 1 zero means there can be only one number
Answer:
See explanation
Step-by-step explanation:
Selected theme park admission prices has the lower standard deviation.
Specific home stereo system's distribution is more spread out since the ratio between the standard deviation and the mean is greater compared to that of selected theme park admission prices.
specific home stereo system: 3.99/59=0.0676.
selected theme park admission prices: 4/1499=0.002668
0.0676>0.002668
First, find 10% of 45
45 x 10/100 = 4.5
subtract that from the original price to find the discount:
45 - 4.5 = 40.5
find 15% of 40.5:
40.5 x .15 = 6.075
subtract the discount:
40.5 - 6.075 = 34.425
$34.425 is the discounted price
