So, Anna has a markers, Ben has b markers and Cindy has c markers. 
We know that a+b+c = m.
And we know also that a = 2b. (<span> twice as many markers as ben has</span>)
(Remember b is the number of Ben markers.)
The equation becomes:
2b+b+c=m.
Solving for c:
c=m-3b
Cindy has (m-3b) markers.

If an endurance athlete jogs 9miles per hour. How many minutes does it take the athlete to jog 1.2 miles?
Novosadov [1.4K]

It takes the athlete 8 minutes to jog 1.2 miles.

Step-by-step explanation:

Given,

Distance covered by athlete in one hour = 9 miles

1 hour = 60 minutes

Therefore;

9 miles distance is covered in 60 minutes.

9 miles = 60 minutes

1 mile = \frac{60}{9}\ minutes

1.2 miles = \frac{60}{9}*1.2=\frac{72}{9}

1.2 miles = 8 minutes

It takes the athlete 8 minutes to jog 1.2 miles.

3 Xavier sketches several designs for a math club
adelina 88 [10]

Answer:

D ...

Step-by-step explanation:

Use the Pythagorean Theorem to figure out which triangle is NOT a right triangle. Square each leg and add them together. Then, square the hypotenuse (longest side). If the sums are equal, then the triangle IS a right triangle.

Pythagorean Theorem:

a(a) + b(b) = c(c) ; a squared plus b squared equals c squared

6(6) + 24(24) =? 26(26) ; leg a =6, leg b=24, hypotenuse=26

36 + 576 =? 676 ; simplify

612 =? 676 ; is 612 equal to 676?

Helpppppp ,would this just be -1.2?
brilliants [131]
<h3>Answer:   1.2</h3>

Explanation:

The result of any absolute value function is never negative. It represents distance on a number line.

The distance from -1.2 to 0 on the number line is exactly 1.2 units.

So that's why |-1.2| = 1.2

In short, we erase the negative sign.
