10 times 50 equals 500. So 500 stripes on 50 buttons.
Answer:
r = 4
Step-by-step explanation:
If we clearly observe a point and the slope of the line are given.
Point=(5, -6) slope= -5
We know that the equation of the line having slope m and passing through point (
) is
Now the equation of the line is 
Now given that (3,r) lies on this line
r = 4
Month 1
Sister 1; 60/ Sister 2; 60
Month 2
Sister 1; 80/ Sister 2; 60
Month 3
Sister 1; 100/ Sister 2; 100
On month 3 the should both have $100 in their accounts.
1-When you have a the logarithm given in the problem above, you can solve it by using the correct properties for logaritms.
2- The students could solve it as below:
<span>log4(2x-12)=3
4^[</span> log4(2x-12)]=4^3
3- By definition a^log(x)=x, therefore,
2x-12=4^3
2x-12=64
4- Now, the students can solve for x:
x=38
The first step is incorrect, because the term on the right member must be 4^3.
