Answer:
Step-by-step explanation:
There's no picture attached, but basically what this means is any value of x should be 2 times y.
Answer:
Step-by-step explanation:
Opposite angles in an inscribed quadrilateral are supplementary, so ...
∠B +∠D = 180°
(3x -4) +(2x -6) = 180
5x = 190 . . . . . . . . . . . add 10, collect terms
x = 38 . . . . . . . . . . . . . divide by 5
∠D = 2(38) -6 = 70
∠B = 180 -70 = 110
The measures of angles B and D are 110° and 70°, respectively.
The picture is the third one and the equation is a² + 11² = c²
Step-by-step explanation:
- Step 1: In the first step of the answer, the given words are find the length of a. Equation is 20² + 8² = a².
The picture corresponding to this is the third picture.
- Step 2: For the second step, words given are find the length of c.
The corresponding equation is a² + 11² = c²
Answer:
r = va/(e - v)
Step-by-step explanation:
v = er/(r + a)
vr + va = er
va = er - vr
va = r(e - v)
r = va/(e - v)
Answer:
graphing : Find the intersection points
substitution method : If you have e.g. x+2y=9 and x=3+2y, we can substitute it, (3+2y)+2y=9
elimination method : Make two variables the same, minus them and solve the equation
Step-by-step explanation:
