Fitness instructor recommend a workout of both cardio and strength at a ratio of 7: 4 minutes how many minutes of cardio would be recommended for 20 minutes of strength

The instructor recommended cardio minutes for 20 minutes of strength are:

Step-by-step explanation:

You must identify the following proportions within the text:

With the given data, a simple rule of three can be performed as shown below:

So it can be seen that the answer is 35 minutes, another way to identify it that the force time became 5 times greater than in the first case (20 is five times greater than 4), therefore, it is logical that the cardio minutes have been multiplied proportionally (7 * 5 = 35).

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
