10•8=80
so something times 80 will equal 400
80•5=400
Answer:
Both sides of the equation are equal to each other.
Step-by-step explanation:
½ (8x+4) = ¼ (8+16x)
(1/2*8x) + (1/2*4) = (1/4*8) + (1/4*16x)
4x + 2 = 2 + 4x
(4x - 4x) + 2 = 2 (+ 4x - 4x)
2 = 2
In order to graph the relationship, we will need to write the expression as the equation of a straight line as shown:
d = mt + b
d is the distance covered
t is the time taken
m is the speed
If you are skateboarding at a pace of 30 meters every 5 seconds. your friend is in-line skating at a pace of 9 meters every 2 seconds, this can be written as (5, 30) and (2, 9)
Get the slope of the line:
m = (9-30)/(2-5)
m = -21/-3
m = 7
Substitute m = 7 and the coordinate (2, 9) into the equation y = mt + b
9 = 7(2) + b
9 = 14 + b
b = -5
The required equation to plot will be expressed as y = 7t - 5
