Tuesday:
1. If Carol can run 5/6 as fast as Jim and Jim can run 1 mile in 12
minutes, how fast can Carol run in a mile?

14.4, 72/5, or 14 2/5 minutes.

Step-by-step explanation:

To do this, you take the 12 minutes Jim can run a mile in, and multiple it by 6/5, or divide 12 by 5/6, either work.

From there, you'll get 14.4, or if you need a fraction there's 72/5, or 14 2/5.

To test if this answer if correct, you can multiply 14.4 by 5/6, and you'll find that it is 12, meaning the answer if correct.

Hope I helped!

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

2 over 5 and 4 over 15

don’t know last one sorry
