Answer:
Step-by-step explanation:
2( N+ 17) = 3 (N +7)
2N+ 34= ·3N+ 21
N= 13
D= N+8 = 13+8 = 21
Fraction is 
When Im using N is equal to numerator and D for denominator, in order to get the fraction we substitute and the results combine in the fraction like this 
Draw 27 circles and take off 4.5 circles for every hour. The answer will be 6 hrs.
Expression:
-27/-4.5 I believe
Plug the points into the equation.
Ex. y=3x-5
(X,y)
1. (5,10): 10=3(5)-5
15-5=10; point 1 is valid
-1=3(-2)-5
-1=-6-5
-1 does not equal -11
Point 2 is not valid
Same process for letter B
Hi there! The answer is 10 miles.
Let the distance be represented by b.
The cost if the ride will therefore be
$5 + ( $3.70 × d )
We end up with the following equation

Subtract 5 from both sides.

Divide both sides by 10.

Therefore, Emma had a taxi ride of 10 miles.
Answer:
Ans= 6720 ways
Step-by-step explanation:
From Combination rule from Permutation and Combination, nCr
We use 8^C3 or 8C3,
8x7x6x5x4x3x2x1
-------------------------- =6,720
3x2x1
or
8x7x6x5x4x3! /3!, here the 3! cancels each other out, and we're left with 8x7x6x5x4, which equals 6720.
