After reading and comparing the values, we get the following answer.

Number of students with blue eyes blond hair  are 42.

Difference of the number of students with gray eyes and brown hair and number of students with green eyes and black hair is 11-5=6

Number of students with gray eyes brown hair  are 5.

Difference of the number of students with green eyes and blond hair and the number of students with gray hair is 35-21=14 because only gray hair marginal total is 35.

Carlos and Maria drove a total of 233 miles in 4.4 hours. Carlos drove the first part of the trip and averaged 55 miles per hour
11Alexandr11 [23.1K]
So basically
D=RT
distance=rate times time

D=233
carlos speed=55
maria speed=50
total time=4.4 hours

so therefor we have to represent
carlos time
maria time
carlos distance
maria dstance

let's say that
remember that whatever carlost drove is 233 minus maria (time and distance)
and since we are solving for maria time and distnace, solve in terms of them
maria time=t
maria distance=d
carlos time=4.4-t
carlos distance=233-d

remember total D=RT
find their seperate equations
carlos
233-d=55(4.4-t)

maria
d=50(t)
use them to solve

233-d=55(4.4-t)
subsitute 50(t) for d
233-50t=55(4.4-t)
add 50t to both sides
233=55(4.4-t)+50t
distribute using distributiver protperty (a(b+c)=ab+ac)
55(4.4-t)=242-55t
233=242-55t+50t
add like terms
233=242-5t
add 5t to both sides
233+5t=242
subtract 233 from both sides
5t=9
divdie both sides by 5
t=1.8
maria drove 1.8 hours

the answer is A

Please show work on how you got the answer
Maurinko [17]
Since E is the midpoint, DE and EF are the same length.
Set the equation DE and EF equal to each other and solve for x.
2x + 4 = 3x - 1
x = 5
Then plug in 5 to find the length.
DE = 2(5) + 4 = 14
EF = 3(5) - 1 = 14
DF = DE + EF = 28

If you worked for 6 days for a total of 67.8 hours. If I worked the same number of hours each day, how many hours did I work in
Hunter-Best [27]
Hi there!

To solve this problem, we need to divide 67.8 by 6 to find the amount of hours each day. 

67.8 / 6 = 11.3

You worked 11.3 hours each day. 

Hope this helps!
