I really need to solve this

Mathematics

Daniel [21]3 years ago

The answer is B. You need to find a common denominator. B) 1/4 - 1/5 = 1/20. To get a common denominator, multiply 5 and 4 to get 20. The common denominator is now 20. Now you have to multiply the numerators by the opposite denominator. This gives you 5/20 - 4/20 which equals 1/20 because you are subtracting the numerators, 5 and 4.

Use the table to work out the values of a , b , c , and d .​
scZoUnD [109]

Answer:

a = - 1, b = - 3, c = - 5, d = - 6

Step-by-step explanation:

Substitute the appropriate values of x into the equation and evaluate

x = - 3 : y = - (- 3) - 4 = 3 - 4 = - 1 → a

x = - 1 : y = - (- 1) - 4 = 1 - 4 = - 3 → b

x = 1 : y = - 1 - 4 = - 5 → c

x = 2 : y = - 2 - 4 = - 6 → d
