Answer:
The unknown is 100
Step-by-step explanation:
A straight line is 180 degrees
We have two angles x, and 80
x+80 = 180
x = 180-80
x= 100
Answer:
See explanation
Step-by-step explanation:
1. 15x+3m. 15 represents the fee per ride, x, and 3 gets added to the total cost depending on how many miles, m, you go.
Everytime you see per, that usually means "some value times a variable"
2. 17 miles would cost 66. 15(1)+3(17)= 15+ 51= 66.
3. 10 miles, because 15(1 ride)+3(10 miles)= 45 dollars.
I tried
400 quarters
$1 = 4q
4q • 100 = 400
400q=$100
S= a(1-r ⁿ) /(1-r) & when r is < 1 & n →∞, the sum becomes S= a/(1-r)
Progression P is 2,1, 1/2,1/4,.. ==> r = 1/2
Sum of P when n--> ∞ = 2/(1-1/2) ==> S =4
Progression Q is 3,1,1/3,1/9,....==> r = 1/3
Sum of Q when n--> ∞ = 3/(1-1/3) ==> S =4.5
GIVEN THAT 4, 9/2 & X (to be calculated later is a geometric Progression, hence 9/2 - 4 = 0.5 =d (common difference , so X = 4.5+0.5 & X = 5
Sum of R =5 Then => 5= 4 /(1-r) & r=1/5
Then the sum of R = 4/(1-1/5) ==> S of R =5
It would be the fourth choice, 3y.
Remember, to get the product of two numbers, you must multiply them together.
Difference=subtraction
Sum=addition
Quotient=division
