First, find what one lightbulb costs.
9.85 / 5 = 1.97
Then multiply the product by 7.
1.97 * 7 = 13.79
Seven light bulbs will cost $13.79
Answer:
The true statements are (D) and (E). This is a square with sides equal to 5 units so that means that its perimeter is 4×(5 units) or 20 units and its area is (5 units)×(5 units) or 25 units^2.
2(-n-3)-7(5+2n)
First, you need to distribute the numbers in front of the parentheses to those in the parentheses. This means you multiply.
2 times -n= -2n
2 times -3= -6
-7 times 5= -35
-7 times 2n= -14n
This leaves you with
-2n -6 -35 -14n
Next, combine like terms.
(-2n) + (-14n)= -16n
(-35) + (-6)= -41
This gives you
-16n-41, which is B in your answer choices.
Hope this makes sense!! :)
She puts 8% of her salary in, so multiply her pay by 8% to get her yearly amount she saves:
45000 x 0.08 = $3,600 per year.
The company puts 6% of that in the account:
3600 x 0.06 = $216
So per year 3600 + 216 = $3,816 is saved.
3,816 x 2 = $7,632 is the 2 year total.
The answer is A.
Since there are two halves in a whole, you can times each number by 2 to get the number of halves it has.
12*2=24
10*2=20
13*2=26
15*2=30
8*2=16
5*2=10
