Answer:

12 minutes 40 seconds

Step-by-step explanation:

One keychain, 1 minutes 35 second = 1*60 + 35 = 95 seconds

8 keychains, 95 * 8 = 760 seconds = 760/60 = 12.66667 minutes

= 12 minutes 0.66667*60 seconds

You are planning on using circles to compare the populations of California 37,691,000, Texas 25,675,000, and New York 19,465,000
Illusion [34]
The question above may be answered through the concept of ratio and proportion. The ratio between the population of a certain city and the radius of the circle used should be proportional. Mathematically, 
                             19465000/5 = 37691000/x₁ = 25,675,000/x₂
The values of x₁ and x₂ are 9.7 cm and 6.6 cm, respectively.

How do i find the slope-intercept form for 6x=8y+10
Mamont248 [21]

Answer:

y = 3/4x - 5/4

Step-by-step explanation:

6x=8y+10

Well you must first get your equation set up into the form called "Slope intercept."

6x=8y+10

Add 8y on both of your sides because your y is suppose to be alone.

8y + 6x = 10

Subtract 6x on both sides since it is in fact the opposite of addition.

8y = 6x + 10

Now, you will divide by 8 on both sides. When doing this your y will be alone.

y= 6/8x + 10/8

Note: You can leave it like this but you want to probably simplify.

y = 3/4x + 5/2

      or

y = 3/4x - 5/4

(Hope this helps can I pls have brainlist (crown)☺️)
