If we apply the distributive law to right side of the third choice we get:-
-12x - 9 = -9 - 12x
right side = left side so infinite solutions
To solve you first need to pick out the most important information,
~Spent 20 minutes
~Each prob takes 2 minutes
Lets have y be the total time spent, and x the number of probs
(y/2) = x
Hope this helped!! ^-^
But its still not that much info what is the answers for it if there is no answer
How are you finding what does x equal
Answer:
30
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem to find the missing side
a^2 +b^2 = c^2 where a and b are the sides and c is the hypotenuse
x^2 + 40^2 = 50^2
x^2 +1600 = 2500
x^2 = 2500-1600
x^2 = 900
Take the square root of each side
sqrt(x^2) = sqrt(900)
x = 30
Answer:
you answer is <u>7x - 16</u>
4x - 1
