6b2 - 13b + 3 = -3 answer?
iogann1982 [59]
No because you say you circle the (6b)2-(13b)+3+

6b-13b= 7b
2+3= 5 
So your answer is 7b-5 because you cant take a variable and a regular number and make it into a complete answer

Eight times the reciprocal<br> of a number equals 4 times<br> the reciprocal of 10.
saveliy_v [14]

Answer:

8(1/x) = 4(1/10)

Step-by-step explanation:

lets say the number is x

eight times the reciprocal of a number equals 4 times the reciprocal of 10

  8       *                       1//x                            =        4    *         1/10

8/x = 4/10 ,  cross multiply

4x =8*10, divide both sides by 4

x= 80/4

x= 20
