Expand 8(5-r)/5=-2r as indicated: 40 - 8r
----------- = - 2r
5
Multiply both sides by 5, obtaining 40 - 8r = - 10r
Combine like terms: 40 = - 2r
Divide both sides by -2: -20 = r
The solution to 8(5-r)/5=-2r is -20. Verify this by subbing -20 for r in the given equation.
Answer:
plugging in the fractions into a calculator would make this super easy
Step-by-step explanation:
5/6 = six divided by five, right? okay so just that down and solve it
Fractions are just a number divided by another number to get a percentage
Think about 1/2, thats 50 percent right? Its half of something
So yeah, you just gotta divide both sides and see which number is bigger, for example
5/6= 0.833
and
3/8= 0.375
So which number is bigger? 0.83 is bigger of course sooooo
5/6 > 3/8
Answer:
y = 2.4
Step-by-step explanation:
If y varies inversely as x, it means there's an inverse relationship between y and x, that is if x is increasing, y is decreasing and vice versa. In such instance, we have to find the constant of proportionality "k"
Hence,
y~1/x
y=k/x
When y =-6 and x =-2, we insert these values to find the value of the constant "k"
-6 = k/-2
k = 12.
Using this value of k to determine value of y when x =5 becomes:
y = 12/5
y = 2.4
Answer:
Step-by-step explanation: #1 is 5 because 5/1 is in the m slot and #2 is 2
Answer: 3
Step-by-step explanation:
A simple way to calculate the distance between numbers on a number line is to count every number between them. A faster way is to find the distance by taking the absolute value of the difference of those numbers. We have to find PQ. TAking the difference we have 94-91= 3.
