Answer:

Step-by-step explanation:
Given that the 2 triangles are congruent based on the Hypotenuse-leg theorem, this implies that:
, and
Using the expression,
, solve for y:



(34-4) + 65) X 45
(30 + 65 X 45
30 + 2925
2955
Answer:
I believe the Science Students have a higher average grade on their respective tests.
Step-by-step explanation:
The mathematics students all scored between 30-40 on their test while the science students scored between 40-50%. This shows that the science students had a larger average score. Hope this helps! Have a great day :)

Multiply 20 by 5 to get 100 so multiply the 3 by 5 also to get 15% of the days.
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
