Answer:
x=k/4+c/4
Step-by-step explanation:
4x-c=k
4x=k+c
x=k/4+c/4
Answer:
3 jeans and 5 sweaters
Step-by-step explanation:
This is a solid guess
However, this is a straight forward question.
175 she has to spend all of it.
To make it an even number you minus 25.
Than you have 150, minus another 50.
You have 5 more clothes to buy, and $100 left.
You use the rest to buy sweaters, therefore spending all the money and getting 8 clothing.
Answer: 24 & 72
Step-by-step explanation: 24 + 72 = 96
24 x 72 = 1728
Let's make things easier by simplifying things.
y = 8 and x = 3 is more likely to be understood as a ratio. So for the rest of the answer, their relationship would be represented as y:x
Thus: y:x = 8:3
The problem would be finding y when x = 45
Let us proceed on using the previous equation and substitute x with 45 which would look like this:
y:45 = 8:3
Ratios can also be expressed as fractions which would make things more understandable and easy to solve. So the new form of our equation would be like this:
y/45 = 8/3
Then we proceed with a cross multiplication where the equation becomes like as what is shown below:
3y = 45 * 8
From there, you can solve it by multiplying 45 and 8 then dividing the product with 3 to get y
3y = 360
y = 120
Another way of looking at the problem, especially problems like these, is to take the whole question or statement as an equation. it would probably look like this:
y = 8 when x = 3 : y = ? when x = 45
This would make you understand what approach you can use to solve the given problem.
X = 13/2 or 6 1/2. Hope this helps!
