Answer:
10:40
Step-by-step explanation:
3x4 = 12
4 x 4 = 16
5 x 4 = 20
so 10 x 4 = 40 (10:40)
It' 185.
Poof:
This is an arithmetic progression with 1st term = 1 and d= 1, common difference
Term ranked "n" = a₁ + (n-1).d
Term ranked 185th = 1 +(185-1)x1 = 185
In order to solve this you have to use the pythagorean’s theorem, which is a^2+b^2=c^2. from the problem you can find out you have a=13ft and c=24ft. c is your hypotenuse. you then solve and you get b=20.17ft. you can check to make sure the answer is right, but that is how you solve it. And the ladder would reach 20.17ft.
Answer:
-1/13
Step-by-step explanation:
5-x= 12x + 4
5-4=12x + x
1 = 13x
-1/13 = x
Step-by-step explanation:
it is like a regular addition of numbers. you add the different positions.
3x + 7x = 10x
-y + y = 0
-5 + 15 = 10
so, D. is the right answer : 10x = 10
