4(b + 5) = 3b + 35. what is b​

b = 15

Step-by-step explanation:

4(b + 5) = 3b + 35

Distribute:

4(b + 5)

4(b) = 4b

4(5) = 20

4b + 20 = 3b + 35

Combine like terms:

4b - 3b = 35 - 20

b = 15

Step-by-step explanation:

4(b+5)=3b+35 perform multiplication on left side

4b+4(5)=3b+35

4b+20=3b+35 Subtract 20 from each side

4b=3b+15. subtract 3b from each side

b=15

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

34
