It’s 90 miles. 30 x (3/1)<— the reciprocal of 1/3
Answer:
you should do 3 and a half lessons
Step-by-step explanation:
45 divided by 13 is 3.5
hope it helps :)
(7h)^3
=(7h) (7h) (7h)
=7×7×7×h×h×h
343h^3
I use that example all the time
A is equal to 50 since 50+10=60 and 50-10=40 so that means b=10. a/b would be 50/10 which is equal to 5
If that says 10x^2 and -5x^2 then the answer is x= -2/5, x=4/3
First get all the variables on one side, so you have 15x^2-14x-8=0. Use the abc factoring method and get factors 6 and -20.Since a is not one, you must group the factors like this (15x^2-20x)(6x-8). Factor those out to get 5x(3x-4)+2(3x-4). Now you put those together to get (5x+2)(3x-4). Set them equal to zero and solve for x. 5x+2=0 ends up being x=-2/5 and 3x-4=0 ends up being x=4/3. Hope that helps!
