the density of the American white oak tree is 752 kilograms per cubic meter if the volume of a American oak is 12.89 cubed. What is the approximate number of kilogram of the trunk

Answer:

Students can earn a Distinguished Level of Achievement under the Foundation program by completing four credits in math (must include Algebra II) and four credits in science, and obtaining at least one endorsement.

Explanation:

Answer:

Explanation:

We know there are 21 students in all, so that should be the denominator in this answer.

Then, to find the numerator, we need to find the number of students that play basketball and the number of students that play baseball, assuming that none of them play both sports. Just add those two numbers to get the numerator, and then put it on top of the 21.

You either typed this question incorrectly, or there is a mistake, because there are more kids that play basketball or baseball than there are students in the class.

Answer:

The answer is E

Explanation:

Before we find the value of 5, let's find x by using the elimination process for the two given equation.

2(3x + y + z = 14) → 6x + 2y + 2z = 28

3x + 2y + 2z = 19

-6x + 2y + 2z = 28

-3x = -9

x = 3

Now plug in 3 into both of the given equations, which will give you your new equation, then subtract them:

3(3) + 2y + 2z = 19 → 9 + 2y + 2z = 19

3(3) + y + z = 14 →   - 9 + y + z = 14

Our answer is: y + z = 5

Our value is 5

Optional: If you want to make sure it's 5, plug-in any random numbers for y and z that equals 5. For example: 3 + 2, 1 + 4, 5 + 0, 6 + (-1), etc...

Once you choose the numbers you can plug them into the two new given equations. For me, I decided to let y = 1 and z = 4:

9 + 2(1) + 2(4) = 19     9 + (1) + (4) = 14

9 + 2 + 8 = 19            9 + 1 + 4 = 14

19 = 19                       14 = 14
