anastassius [24]
What you do is you find the common denominator between the two fractions given.  the easiest is to just multiply them 

6*8=48

and then multiply each numerator by the number it's denominator is multiplied by

1*8=8  and 5*6=30

and now you have your new fractions, add them together

8/48+30/48=38/48

this leaves 10/48 as the people who were wearing shorts,  just simplify this and it's done

What is the equation of a line that is parallel to −x+3y=6 and passes through the point (3, 5) ?
oksian1 [2.3K]
3y=6+x
y=(6+x)/3
y=2+x/3
y=mx+b
y=x/3+b
so m(slope) is 1/3
use the point (3, 5), sub this for x and y
5=3/3+b
5-1=b
b=4
therefore, y=x/3+4
or y=(1/3)x+4 (you can write it like this as well)

dem82 [27]

Answer: R(t) = 750 + 0.04t

Step-by-step explanation:

Here's the complete question:

Ebuka's monthly rent is $750. If Ebuka pays the rent late, his landlord charges 4% interest per week that the payment is late. Write a function that gives the total cost R(t), in dollars, of Ebuka's rent if he pays it t weeks late.

The above question will be represented by:

R(t) = $750 + (4% × t)

R(t) = 750 + (4/100 × t)

R(t) = 750 + 0.04t
