Okay so you're trying to find the unit rate of 720yds/4min. If you divide 720 by 4 you will have the unit rate as 180yds/1 min or 60 sec then if you divide 180 and 60 by 4 again you will get the answer of 45yds/15sec.

A number increased by three is the same as quadrupling that number increased by five all divided by four. What is le number?
IrinaVladis [17]

Answer:

The number is infinity

Step-by-step explanation:

Let the unknown number be x

if the number increased by three, then we have;

x + 3

Also quadrupling that number increased by five all divided by four is expressed as;

(4x+5)/4

Equating bith expressions and calculating x;

x+3 = (4x+5)/4

cross multiply;

4(x+3) = 4x + 5

4x+12 = 4x + 5

4x-4x = 5 - 12

0x = -7

x = -7/0

x = ∞

Hence the number is infinity

Determine the intercepts of the line y=5x-13
bonufazy [111]
Intercepts can either be an x-intercept or a y-intercept. Both intercepts can be determined by simply setting the other variable to be zero. For instance, to obtain the x-intercept, we must  equate the y value of the equation to zero and vice versa. 

x-intercept: Setting y=0
y=5x-13
0=5x-13
5x=13
x=13/5
y-intercept: Setting x=0
y=5x-13
y=5(0)-13
y=-13

Therefore, the intercepts are y=-13 and x=13/5 or (0,-13) and (13/5 ,0) in point form.
