In jefferson middle school, 5% of the sixth graders have red hair. if there are 100 sixth graders, how many

5 have red hair among 100 sixth graders

Step-by-step explanation:

100*5% = 5

or

100*5/100 = 5

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
