Answer:
$5.05
Step-by-step explanation:
$30-4.75=25.25 (cost of total pens)
25.25÷5=$5.05 (there are 5 pens so divide by 5)
Answer:
11 1/2 years old
Step-by-step explanation:
Let Amanda's age be a.
Let the company's age be c.
The company is 24 years older than Amanda. This means that:
c = 24 + a ______(1)
The sum of Amanda's age and the company's age is 121 years. This means that:
c + a = 121 ________(2)
Put (1) in (2):
24 + a + a = 121
2a = 121 - 24
2a = 97
a = 97 / 2 = 48 1/2 years
She has been there for 37 years, therefore, her age when she started working there is:
48 1/2 - 37 = 11 1/2 years old
NOTE: This age doesn't seem right but I worked based on the parameters given.
Answer:
a.) x>-1
b.) x/1 - 9 < -10
Step-by-step explanation:
a.)
5(x - 2) > -15
(divide both sides)
x-2>-3
(move the constant to the right)
x>-3+2
(calculate)
x>-1
(answer)
b.)
x/1 - 9 < -10
(divide)
x-9<-10
(move the constant to the right)
x<-10+9
(calculate)
x/1 - 9 < -10
(answer)
Answer:
negative $1.60 was the "interest" added to Vito's account
Step-by-step explanation:
new balance = old balance + deposits - withdrawals + interest
$9669.26 = $6955.01 + 2815.85 - 100.00 + interest . . . . fill in givens
$9669.26 = $9670.86 + interest . . . . . simplify
$9669.26 - 9670.86 = interest = -$1.60 . . . . . subtract 9670.86

<em>Comment on the problem</em>
This result is "unexpected." Usually an interest amount will be positive. Please have your teacher work this problem for you and explain the result.
I’m going to use the second one to explain
-8j + 14 = -2(4j-7)
So you distribute -2 into the parentheses on the right side, and you get -8j + 14, which is the same as the left side. Therefore, it is a true statement. It turns from a - to a + because it is two negative numbers multiplying by each other.
