Answer:
6) x=5
7)x=6
8)x=10
9)x=12
Step-by-step explanation:
6) 3x-5=10. 7) 36=4x+12. 8) 3(x+2)=36
+5 +5. - 12. - 12. 3x + 6=36
3x = 15. 24 = 4x. - 6. -6
÷3. ÷3. ÷4. ÷4. 3x=30
x=5. 6 = x. x = 10
9) 7(2x-15)=63
14x - 105=63
+105. +105
14x = 168
÷14. ÷14
x=12
V = 4/3πr³
V = 4/3(3.14)(14)³
V = 4/3(3.14)(2744)
V = 4/3(8616.16)
V = 11488.21333cm³
Answer:
1/9
Step-by-step explanation:
The possible choices 2,3,4
odd numbers: 3
P (odd number) = number of odd numbers /total
= 1/3
Then we spin again
The possible choices 2,3,4
We want a 3: 3
P (3) = number of 3's /total
= 1/3
Since the first spin did not affect the second spin
P(odd, then 3) = P(odd) *P( 3)
= 1/3* 1/3
=1/9
Answer:0
Step-by-step explanation:3b(-27 + 9b) = 0
(-27 * 3b + 9b * 3b) = 0
(-81b + 27b2) = 0
Answer:
Step-by-step explanation:
If u are saying 12/5, 5 goes into 12 2 times which is 10. there is 2 left so it is 2 and 2/5
