<span>let's say, you have 2(x+5)=10 
What you  do is multiply the x and the 5 by 2 so it now looks like 
2x+10=10 

The act of multiplying the inside numbers by the number outside the parenthesis is the distributive property. Now using distributive property to remove grouping symbols is  similar 
</span>Lets say you have 18 + {2 + 3 (6 -1*2)} first you would multiply 2by1

= 18 + {2 + 3(6 - 2)} then subrtact 2 from 6 

= 18 + {2 + 3(4)} then multiply 3by 4  take away () grouping signal

= 18 + {2 + 12} then add 2 and 12

= 18 + {14} then take away the last grouping signals 

= 18 + 14 then add 18 and 14 

= 32

Bob believes his test grade varies directly with the number of hours he spends studying and inversely with the number of hours h
Readme [11.4K]

Answer: Hello mate!

A direct variation implies that, if y is the dependent variable that varies with the variable x; then: y = k*x where k is a real number.

An inverse variation has the form y = k/x where also k is a real number.

them, if we define s as the hours that Bob spends studying, and b as the hours that he spends playing baseball, then the equation that represents the score is:

Score(s,b) = k*s/b

we know that if s = 6, and b = 7, then the score is 72; with this information, we could obtain the value of the constant k.

score(6,7) = 72 =k*6/7 = k*

then  k = 72*(7/6) = 61.7

now if s = 4 and b = 6, the score that he should expect is:

score( 4, 6) = 61.7*(4/6) = 41
