Answer:
each ouce is worth 25 cents
solution
in order to solve this you need to create proportions so
<u>10 ounces </u>
per $2.50
well you want this to be a unit rate so you would have
<u>10 ounces </u> =<u> 1 ounce</u>
2.50 x
to get to the unit rate, you can see that you divided 10 from 10 ounces so you would do the same to the bottom ...
2.50/10 which is equal to 0.25.
Answer:
hi have a great day i dont know about this
Step-by-step explanation:
for all positive integers (like n = 1, 2 or 5) the conjecture holds true but not for negative values like if n = -3 then the result will not become positive, because:
which is not positive.
Answer:
x=7 and y=2
Step-by-step explanation:
In this case, you want to use elimination
1. multiply the second equation by -1
5x + 3y = 41
2x + 3y = 20
turns into
5x + 3y = 41
-2x + 3y = 20
2. combine the equations
3x=21
3. solve for x
3x=21
3x/3=21/3
x=7
4. Now you want to plug x back into the original equation
5x+3y=41
turns into
5(7)+3y=41
5. Then solve for y
35+3y=41
35+3y-35=41-35
3y=6
3y/3=6/3
y=2
6. results
x=7 and y=2
