A reciprocal of the number or a certain expression is the multiplicative inverse of a certain numbers. This means that the numerator of the original number becomes the denominator of the reciprocal and the denominator of the original number becomes the numerator of the reciprocal.
In this item, the numerator is -8b and the denominator is 5b - 6. The reciprocal of the expression will then be equal to,
R = -(5b - 6) / 8b
Answer:
3/10, 2/5, 7/10, 3/4
Step-by-step explanation:
3/10 is 30%. 2/5 is 40%. 7/10 is 70%. 3/4 is 75%. Or you could multiply the denominators so that all denominators have the value of 20. Then it can be arranged. For 3/4, you can multiply everything by 5 to get 15/20. for 3/10, you can multiply everything by 2 to get 6/20. For 2/5, you can multiply everything by 4 to get 8/20. And for 7/10, you can multiply everything by 2 to get 14/20. Now you can arrange everything, starting with 3/10, then 2/5, then 7/10, and finally 3/4.
They answer is 12.t obeys
Changing those words into an equation, we get:
7+3x = 19
Subtract both sides by 7
3x = 12
Divide both sides by 3
x = 4
That number is 4. Have a nice day! :)
