Hey I have posted a picture the method I use to solve simultaneous equations is change the sign and follow the new sign.
This involves changing the sign for the second equation and solving it
1. You have that:
- Each gallon of paint covers 400 ft²<span>.
- One side of a wall must be painted and its dimensions are :is 8 meters tall and 40 meters long.
1 ft=0.3048 m
1 ft</span>²=(0.3048 m)²=0.09290 m²
2. Each gallon of paint covers 400 ft<span>², then:
</span>
400 ft²x<span>0.09290=37.16 m</span>²
3. The area of one side of the wall is:
A=8 mx40 m
A=320 m²
4. Therefore, you have:
1 gallon-----37.16 m²
x-----320 m²
x=320x1/37.16
x=8.61 gallons
x≈9 gallons
The answer is: 9 gallons
Well that would be 105 - 10. If you spent 105 minutes in total and 10 of that was putting your stuff away, take that 10 minutes away and you’d get 95. So, she spent 95 minutes washing 3 cars in total. If you divide that 95 into 3s, you get rounded 31 minutes each.

Answer:
Step-by-step explanation:
Here, we have to find the sum of 2 fractions:
1st fraction: 
2nd fraction: 
Considering the denominator of 1st fraction:
Using factorization method:
can be written as 
.
Taking <em>5 common</em> from 
and <em>y common</em> from 
:
Now taking 
common:
can be written as 
Now, calculating the sum:
Taking <em>LCM</em> and solving:
Hence, answer is .
