There are two red jars of marbles and one blue jar of marbles jars of a certain color have the same number of marbles in them. T
satela [25.4K]
We can set up an equation to solve this problem.  I am setting the number of marbles in a red jar to R.

R + R + R - 16 = 41

We solve this by adding 16 to both sides and combining all of the R terms..  This gives us:

3R = 57

We can finish this problem by dividing both sides by 3.

R = 19.  So, there are 19 marbles in a red jar.

We can easily figure out how many marbles are in a blue jar by subtracting the total amount of marbles in 2 red jars from the total amount of marbles.  I am setting the amount of marbles in a blue jar to B.

41 - 19*2 = B

B = 3

So, there are 3 marbles in a blue jar and 19 marbles in a red jar.

Solve for x . Leave your answer in the simplest form
Alisiya [41]

Hello!

Here we are given a composite shape, meaning that we can divide this shape up into ways that we are given formulas to solve for legs and such.

I can see here that this can be divided into a triangle and a rectangle using a horizontal line.

The leg lengths of this triangle would be 9, because it is congruent to the bottom side of the rectangle, and 7, because it is the left side minus the right side.

This would also make a right triangle, meaning we could solve for the hypotenuse utilizing the Pythagorean Theorem.

a^2+b^2=c^2

6^2+7^2=c^2

36+49=c^2

c^2=85

c=\sqrt{85}

Which is in simplest radical form.

Hope this helps!

Find the radius of a circle that has a circumference of 16
Masteriza [31]

Answer:

The circumference of a circle is equal to π , which is a number ≈3.14 , multiplied by the diameter of the circle. Therefore ... We also know that the diameter has twice the length of the radius. In equation form: 2r=d. 2r=16. r=8. Note that since 2r=d , the equation C=2πr holds and can be used in place of C=πd .
