It is saying that if Mr Newberry had 7 marbles, 3 would be red and 4 would be blue. Basically, the question is asking you to do this:
Red: 28/3 =
Blue: 28/4 =
The equation of line parallel to given line is: y=4x-31
Step-by-step explanation:
Given equation of line is:

The equation of line is in slope-intercept form so the co-efficient of x is the slope of the line.
Let m1 be the slope of the given line
then
m1 = 4
Let m2 be the line that is parallel to given line
As we know that the slopes of parallel lines is equal so
m1=m2 = 4
The slope-intercept form of equation of line is:

Putting the value of slope

to find the value of b, putting (5,-11) in the equation

Putting the value of b

Hence,
The equation of line parallel to given line is: y=4x-31

Answer:
22s - 9
Step-by-step explanation:
The perimeter (P) is the sum of the 4 sides , that is
P = 2s + 7 + 9s - 5 + 6s - 10 + 5s - 1 ( collect like terms )
= (2s + 9s + 6s + 5s) + (7 - 5 - 10 - 1)
= 22s + (- 9)
= 22s - 9

Answer:
14 days
Step-by-step explanation:
Total Problems = 175
Finished Problems = 8
Remaining = 175 - 8 = 167
8 problems in 30 minutes, means:
30/8 = 15/4 = 3.75 minutes per problem
If he works for 45 minutes, at that rate, he can solve:
45/3.75 = 12 problems per day
To finish 167 problems, he will need:
167/12 = 13.91
Rounded, that is <u>14 days more to finish</u>
