Answer:

r = 1

Step-by-step explanation:

In this question, we have to solve for the vallue of "r". We will use the distributive property shown below to ease our process.

Distributive Property:

a(b+c) = ab + ac

Now, lets solve this:

-4r-8(r-6)=7(5r-1)+8\\-4r-8r+48=35r-7+8\\-12r+48=35r+1\\48-1=35r+12r\\47=47r\\r=\frac{47}{47}\\r=1

As we have seen the value of r is "1"

a penny = 0.01....300 pennies = 300(0.01) = $ 3

Is 2/5 bigger than 4/9
Vilka [71]
One way to look at this is that 2/5 = 4/10, but depending on how well you understand fractions, you might not be able to compare 4/10 and 4/9. 

To make it easier to see, we can find a common denominator:
2/5 = 18/45
4/9 = 20/45

No, 2/5 is not bigger than 4/9
