Answer:
Step-by-step explanation:
use these two equations
A: y = 15
B: y = 2r + 5
a) set the equations equal to eachother for your first answer
15 = 2r + 5
B) solve for r
15 = 2r + 5
10 = 2r
5 = r
after 5 rides the cost will be the same
Answer:
y = 2x - 5
Step-by-step explanation:
Step 1: Find slope <em>m</em>
m = (-1 - 3)/(2 - 4)
m = -4/-2
m = 2
y = 2x + b
Step 2: Find <em>b</em>
-1 = 2(2) + b
-1 = 4 + b
b = -5
Step 3: Rewrite equation
y = 2x - 5
The volume is multiplied by 8. For example if you have a 1x1x1 cube the volume is 1. If you have a 2x2x2 cube the volume is 8. If you have a 4x4x4 the volume is 64.
Answer:
198 students walk to the local high school
Step-by-step explanation:
Total number students = 825
1/5 of the students travel by car
48% of the students travel by bus
0.08 of the students travel by bicycle
To find the number of students who wal to school we have to find the exact number of students who travel to school by car, bus and bicycle and subtract the result from the total number of students
Students who travel by car = 1/5×825
= 165 students
Students who travel by bus = 48% × 825
= 48/100 × 825
= 12/25 × 825
= 396 students
Students who travel by bicycle = 0.08 × 825
= 66
So now we add the results fo the equations above and subtract it from the total number of students to get the number of students that walk to school
Students that walk to school = 825 - (165 + 396 + 66)
= 825 - 627
= 198 students
Therefore 198 students walk to the local high-school
An irrational number.
Example: Pi. Pi doesn’t have an ending as far as we know, so it cannot be written as a fraction.
