8 apples were purchased.
4 oranges were purchased.
8 + 4 = 12
Answer:
9. y = 8
10. n = 21
11. 44 = v
12. c = 35
Step-by-step explanation:
9. 9y = 72
Divide each side by 9
9y/9 = 72/9
y = 8
10. 3n = 63
Divide each side by 3
3n/3 = 63/3
n = 21
11. 4 = v/11
Multiply each side by 11
4*11 = v/11*11
44 = v
12. c/7 = 5
Multiply each side by 7
c/7*7 = 5*7
c = 35
-2/3 is a rational number
0.1111.... =1/9 - rational number
-2/3*1/5= -2/15 rational
1/9*1/5=1/45 rational
correct answer A and D
π and √11 are irrational numbers, and when they are multiplied by rational number, they will give irrational number.
Answer:
Graph A
Step-by-step explanation:
3x+y=5
y=-3x+5
4x-y=2
-y=-4x+2
4=2x-2
