a. let us say that:
a = cost of phones with camera
b = cost of phones with camera and mp3
c = cost of phones without any features
b = 2 a – 35
c = a – 100
a + b + c = 525
b > a > c
b. We are given three equations with three unknowns. So
we can solve the problem.
a + (2 a – 35) + (a – 100) = 525
a + 2 a – 35 + a – 100 = 525
4 a – 135 = 525
4 a = 660
a = $165
Answer:
I think true
Step-by-step explanation:
I'm not exactly sure what a linear term means, but I think it would mean the constant in the equation. If it does mean the same thing as a constant, then that would be true. Feel free to correct me if I'm wrong and I'll try to help more if I can
Answer:
Alright solve for x by simplifying both sides of the equation, then isolating the variable
x = - 13/4 Hope this helps :)

Answer:
- Angles 1 & 2 are congruent/equal in measure
- Angles 1 & 3 are supplementary (I'm sure of this part) because they are adjacent and add up to 180° (I'm sure of this part, but I don't know what exact wording they are looking for in your problem)
- Angles 2 & 4 are supplementary (same reasoning as angles 1 &3)
Step-by-step explanation:
Angles in a trapezoid that are adjacent are always either congruent (meaning they have the same measure) or they are supplementary (meaning you take one small angle measuring less than 90° - known as an acute angle - and one large angle measuring more than 90° - known as an obtuse angle - and when you add the two angles together they will always equal 180° - which means they are supplementary).
