Answer:
x = 20
Step-by-step explanation:
The 3 arcs UV, VW, WX form a semicircle, so sum to 180° , that is
4x + 2 + x + 78 = 180
5x + 80 = 180 ( subtract 80 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
Answer:
BC= 20 units
Step-by-step explanation:
Since ∆ ABC is an equilateral triangle, all the sides are equal in length.
AC= BC
=>-y+23= 6y+2
=>-y-6y= 2-23
=>-7y= -21
=>y= 21/7
=>y= 3
BC = 6y+2 = 6(3)+2 = 18+2 = 20 units
Answer:
y = -2

Answer:
I think it is 2x-3y<7, also, I used a free program called Desmos to figure it out, in case you also want to.

Answer:
<h2>28/s</h2>
Step-by-step explanation:
I assume that you are wanting an algebraic expression written. if not, please let me know!
When we divide numbers by each other, we write them as a fraction, the number being divided over the number it's divided by. in this case, the number we're dividing is 28, and the number we're dividing it by an unknown factor s.
