Answer:
5b = 20
Step-by-step explanation:
Since Abdul bought b books and Debra bought 5 times as many books as Abdul, then 5b represents the number of books Debra bought. Since we know that Debra bought 20 books, we can write an equation to represent that: 5b = 20.
(Abdul bought 4 books in that case)
Each step subtracts 3 from the previous number.
14 - 3 = 11
11 - 3 = 8
The sequence will continue:
8 - 3 = 5
5 - 3 = 2
2 - 3 = -1
Etc.
14, 11, 8, 5, 2, -1...
6/56 = 3/28........................
Answer:
x = -2
y = - 5
Step-by-step explanation:
-5y - 10x = 45
-3y + 10x = -5
------------------------Add
-8y = 40
y = -5
-3(-5) + 10x = -5
15 + 10x = -5
10x = -20
x = -2
Answer
x = -2 and y = - 5
First you would have to isolate y.
3x - 3y = 18 -----> Subtract 3x from both sides
-3y = -3x + 18 --------> Now divide both sides by -3
y= x - 6
Now you replace the y with an f(x)
f(x) = x - 6
