Bananas cost: $0.25
Apples cost: $0.30
4b+5a=2.50
10b+3a=3.40
You multiply the equations by the variables so they can cancel out. For example the first one by 3 and the second by 5 so you have
12b+15a=7.50
50b+15a=17
Subtract them and end up with
-38b=-9.5
solve: b=0.25, substitute b in any equation and get a=0.30
Hope this helped
Answer:
(a)6 feet
(b)24 sections
Step-by-step explanation:
(a)We are required to find the length of the Giant Sub.
If each section is 1/3 of a foot long and there are 18 equal parts.
Length of the Giant Sub =
Length per Section X Number of Sections
= 1/3 X 18 = 6 feet
(b)If each section is 1/4 of a feet long
Length of the Giant Sub =
Length per Section X Number of Sections
6= 1/4 X Number of Sections
Number of Sections =6 X 4 =24 sections

Well to solve this, lets plug in some numbers. Lets assume that for now, the starting number is 2. If it increases by 100%, bringing it up to 4, then decreases 100%, it is brought down to zero. Now one thing to note is that any number decrease by 100% is automatically zero. Watch, we start with two, it is then increased by 150%, bringing it up to 5, then decreased by 100%, bringing it back down to zero. In conclusion, 100% cannot be specified as a value, but rather a relation. 100% represents the entire number, meaning that if you are decreasing a number by 100%, you are basically subtracting the number by itself!
Answer:
Step-by-step explanation:
1 quart of wax makes 6 candles
If 30 candles is to be made then 5 quart of wax is needed
The quart is made up of
2 part of red
5 parts of yellow
3 Parts of white
Total= 10 part to make the Orange shade
We knew Yellow is 5 part out of 10 part as written up
Hence, yellow will be 2.5 part in 5 quart
