add the two equations together
5a+5b=25
-5a+5b=35
------------------
0 + 10b =60
divide by 10
b=6
5a + 5b = 25
5a +5(6) = 25
5a +30 =25
subtract 30 from each side
5a =-5
divide by 5
a = -1
Answer (-1,6)
or a=-1 b=6

Answer:
Antoinette's error
Option A) She distributed incorrectly.
Step-by-step explanation:
We are given the following information in the question:
Antoinette solves the linear equation
Antoinette made mistake in step 1 that is she did not distributed correctly.
If she would have distributed correctly, then she would have got the following solution:
Substituting x = -1 in the given equation, we gwt:
Antoinette's error
Option A) She distributed incorrectly.
Answer:
15" by 10"
Step-by-step explanation:
Use a proportion.
10'/5" = 30"/x
10x = 5 * 30
10x = 150
x = 15"
10'/5" = 20'/y
10y = 5 * 20
10y = 100
y = 10"
Answer: 15" by 10"
Hello there,
Okay so the question is asking us to subtract the two mixed numbers, 6 3/5 - 2 4/5, from each other...
The first step would be to change the mixed numbers to improper fractions:
- 6 3/5 as improper fraction would be 33/5
- 2 4/5 as improper fraction would be 14/5
Now we need to make sure that the denominators are the same and in this case they are.
Simply subtract 14 from 33 and you would get 19 and the denominator stays the same so you would get 19/5.
- Now turn 19/5 into a mixed number and you would get 3 4/5
The answer to the 6 3/5 - 2 4/5 would be 3 4/5.
Hope I helped,
Amna
