-2(b-1)=2(1+7b)
First, distribute; -2b+2=2+14b
Get the variables on one side; -2b+2=2+14b
-14b -14b
Get the constants on one side; -16b+2=2
-2 -2
Divide to find “b”; -16b/-16=0/-16
b=0
A
B denotes to all common elements in both A and B
- Sample space=S={1,2,3,4,5,6,7,8,9,10}
So
2 is common
Hence
A $\cap$ B={2}
Answer:
r=8
Step-by-step explanation:
59 =7r+3
Subtract 3 from each side
59 -3 = 7r+3-3
56 = 7r
Divide each side by 7
56/7 = 7r/7
8 =r
-3 1/2 is rational because the decimal ends at -3.5. It is not sqrt(5) because the decimal never ends and the same follows for pi and 9.23157.
