Answer:
no solution
Step-by-step explanation:
Given
(21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )
21 - 3a = 18 - 3a ( subtract 21 from both sides )
- 3a = - 3 - 3a ( add 3a to both sides )
0 = - 3 ← not possible
This indicates the equation has no solution
Answer:
Step-by-step explanation:
The total number of marbles is 24 + 36 + 60 = 120
Red: 24/120 = 1/5
Blue: 36/120 = 6/20 = 3/10
Yellow: 60 / 120 = 1/2
Answer:
x= 10, y= 15
Step-by-step explanation:
because alternate interior angles are congruent
8x -10 = 7x
8x -7x = 10
x = 10
because straighht line form 180°
6y+20 +7x = 180
6y +20 +70 = 180
6y = 180 -90
y=90/6 = 30/2 = 15
