Answer:
option D
Step-by-step explanation:
Jerry solved this equation:
In the first step , she multiplied 3 inside the parenthesis
1. 
In step 2, 3/4 is added on both sides
2. 
In step 3, we take LCD 12
3. 
In step 4, add the fractions
4. 
Here, 3 or 3/1 are same.
In step 5, to remove 3/1 we multiply both sides by 1/3.
Instead of multiplying 1/3 , Jerry made an error by multiplying 3/1
In step 5, he should have multiplied both sides by 1/3
The answer would be 10 because if u put abcde over fghij, hi and cd are the same place so its the same answer or a mulitple of 10
Answer:
x = - 7, y = 6
Step-by-step explanation:
7x + 7y = - 7 -----> equation 1
- 10x - 7y = 28 -----> equation 2
Add equations 1 & 2,
7x + 7y = - 7
- 10x - 7y = 28
___________
- 3x + 0 = 21
- 3x = 21
x = 21 / - 3
x = - 7
Substitute x = - 7 in equation 1,
7x + 7y = - 7
7y + 7x = - 7
7y + 7 ( - 7 ) = - 7
7y - 49 = - 7
7y = - 7 + 49
7y = 42
y = 42 / 7
y = 6
Answer:
(1,4)
Step-by-step explanation:
(x,y)→(1,4)
Answer:
3/4,
12/16,
18/24,
24/32
30/40
...So on, So on...
Step-by-step explanation:
Any fraction that you multiply by the same number on the bottom and on top.
So, multiply by two, what you do to the top do to the bottom. = 12/16
Multiply by three = 18/24
So on, so on.
Or you can reduce, 6/8 divide by 2 = 3/4.
I'm gonna give you 5 equivalent equations. I also taught you how to do it!
