Answer:
+ 2 = 7
Step-by-step explanation:
The quotient of x and 5 is and 2 more is + 2 , then
+ 2 = 7
Answer: A) 2
Step-by-step explanation: I just got it good
Answer:
first Let's find the common difference
an=a1+(n-1)d
let's take A2 that is 18
so 18=7+(2-1)d
18=7+d
d=11
so the next term is going to be 40+11 that is 51
Answer:
I. 1/5
II. -1/14
III. 2/9
Step-by-step explanation:
(i) (-3/5) + (-2/7)
Opening up the bracket;
3/5 - 2/5 =
Lowest common multiple (LCM) = 5
(3 - 2)/5
= 1/5
(ii) (-2/7) - (-3/14)
Opening up the bracket;
-2/7 + 3/14 =
Lowest common multiple (LCM) = 14
(-4 + 3)/14 = -1/14
(iii) (-4/ 9) = (- 2/3)
Rearranging the fraction, we have;
-4/9 + 2/3 =
Lowest common multiple (LCM) = 9
(-4 + 6)/9 = 2/9
The expression which shows the total cost is 2.50+0.4x and the cost of riding 20 miles is $10.50.
Given a taxi charges $2.50 for the first mile and $0.40 for each mile
We are required to make an expression showing total cost and total cost of a 20 mile ride.
let the miles ride by tax be x.
Total cost of the product or service=Number of units*price of one units.
We have been given that $2.50 is fixed so we will not multiply our variable charge with $2.50 and multiply 0.40 with x.
So,the expression showing looks like 2.50+0.40x.
Now to find the cost when taxi travels 20 miles, we have to put x=20,
Cost=2.50+0.40*20
=2.50+(40*20)/100
=2.50+800/100
=2.50+8
=$10.50
Hence the expression which shows the total cost is 2.50+0.4x and the cost of riding 20 miles is $10.50.
