Answer:
His test IS a solution.
Step-by-step explanation:
Both LHS and RHS are equal so it is a solution.
There is 33 students in the class
So this is a special triangle. The 30-60-90 triangle rule states that if the short leg is y, then the hypotenuse is 2y and the long leg is y√3.
In this case, the short leg is 5√3 since that times √3 makes 15.
Now with the hypotenuse, just multiply 5√3 with 2, and your answer should be 10√3, or C.
Answer:
8
Step-by-step explanation:
3 divided by 4.8 = 0.625
5 divided by 0.625 = 8
-2(4x-1)=5+7
(4x-1)=12/-2
4x=-6+1
x=-5/4
