If you're traveling in a line from point A to point B, determining your average ... often use the words speed and velocity interchangeably, they aren't the same!

Step-by-step explanation:

Answer:

B. it will take them 8 hours to drive 400 miles

D. It will take them 18 hours to drive 900 miles

E. It will take them 1 hour to drive 50 miles

Step-by-step explanation:

First, you solve for how fast there going an hour so in three hours they go 150 so we can divide 150 by 3 and we get 50. That means they go 50 miles in an hour. Then we can multiply 50 by the hours and see if we get the same number on miles.

Kayla is given a monthly allowance. She uses 40% of this allowance to purchase a designer bag, and then donates $15 to a charity. If she ends up with $155, which of the equations below can be used to determine what her monthly allowance was?
a. 0.40 X -15 = 155
b. 40 X + 15 = 155
c. 0.60 X - 15 = 155
d. 60 X -15 = 155

Answers

Answer:

A. 0.40x - 15=155

Step-by-step explanation:

40% can be written as 0.40

x = total money earned

-15 from that total

The expression which can be used to calculate her monthly allowance is 0.6X - 15 = 155

Let :

monthly allowance = X

Designer bag purchase = 40% of X = 0.4X

Donation to charity = $15

Total amount left = $155

Percentage left after bag purchase :

1 - 0.4X = 0.6X

0.6X - charity = amount left

Therefore, the required expression is 0.6X - 15 = 155

B. 11n + 4 + n –12
C. 6(6n – 2)
D. 4(3n – 2)
E. 4n + 22 – 12 + 8n

Answers

Answer:

B and D

Step-by-step explanation:

B= 4(3n-2)

D=12n-8 which equals 4(3n-2)

Option B 11n + 4 + n –12 and D 4(3n – 2) are the expressions that are equivalent to 12n-8.

What are equivalent expressions?

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions. To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We are given an expression as; 12n – 8.

A. 3n + 4 + 3n + 4 + 4n

= 3n+3n+4n+4+4

=10n+8

B. 11n + 4 + n –12

=11n+n+4-12

=12n-8

C. 6(6n – 2)

=36n-12

D. 4(3n – 2)

=12n-8

E. 4n + 22 – 12 + 8n

=4n+8n+22-12

=12n+10

Therefore, Option B 11n + 4 + n –12 and D 4(3n – 2) are the expressions that are equivalent to 12n-8.
