Answer:
7/10 or 70% or 0.7
Step-by-step explanation:
4 black, 10 red
10+4=14
now you put it over the total marbles
14/20=7/10
i don't know how your teacher wants you to give the answer but it is 7/10 or 0.7 or 70%
5x-9 = 3x+3
2x-9 = 3
2x = 12
x= 6
plz mark branliest, hopoe this helps :)
15x^2 = 12x
divide each side by x
15x = 12
now divide each side by 15
x = 12/15 or 4/5 which is also 0.8
Answer:
Adults = x
Students = y = x + 40. 40 more student than adult
Adult = $8, Student = $6
Total for Adults = 8*x = 8x
Total for students = 6*y = 6y
Total = $1920
8x + 6y = 1920
Hence system of equations are:
y = x + 40
8x + 6y = 1920
Answer:
Step-by-step explanation:
Refer to the figure and match the theorem that supports the statement.
1. If chords are =, then arcs are =.
If BC = DE, then Arc BC = Arc DE
2. If arcs are =, then chords are =.
If Arc BC = Arc DE, then BC = DE
3. Diameters perpendicular to chords bisect the chord
If AX is perpendicular to BC, then BX = XC
