Answer:
6.7
Step-by-step explanation:
Make a proportion (similar triangles):
(15) / (10+x) = 6/x
15x = 60 + 6x
9x = 60
x = 6.7
Answer:
60
Step-by-step explanation:
We are given the triangles are congruent, that means the angles are the same measurement
<A = <X
<B = <Y
<C = <Z
We know A = 50 so X = 50
We know <Y = 70 so < B = 70
The three angles of a triangle add to 180
<A + <B + <C = 180
Substituting into the equation
50 + 70 + <C = 180
Combining like terms
120 + <C =180
Subtracting 120 from each side
120-120 +<C =180-120
<C = 60
Answer:
The practical domain of the function is the set of all integers from 1 to 5, inclusive.
Step-by-step explanation:
It is given the initial number of sheets of paper is 45.
A store has 5 reams of paper, and each ream contains 500 sheets of paper.
Let f(x) represent the number of sheets after purchasing x reams.

Domain is the set of input. In other words domain is the set of x-values.
Since number of reams can not be a negative or fraction value, therefore, the domain of the function is {1,2,3,4,5}.
Andre needs to buy more sheets, so number of reams of paper can not be 0.
Thus, the practical domain of the function is the set of all integers from 1 to 5, inclusive.
