Z=m-x, solving for x

Leokris [45]

Answer:

<h2>x = m - z</h2>

Step-by-step explanation:

z = m - x <em>add x to both sides</em>

z + x = m - x + x

z + x = m <em>subtract z from both sides</em>

z - z + x = m - z

x = m - z

ASAP Help! Season’s junior high school is celebrating its centennial anniversary. When the school first opened, a tree that meas

anastassius [24]

We have been given that a tree that measured $3\frac{3}{4}$ feet tall was planted. A hundred years later, the tree is now $25\frac{1}{2}$ feet tall. We are asked to find the number of times times is tree now taller than it was when the school first opened.

To solve our given problem, we will divide present length of tree by length of tree when it was planted as:

$25\frac{1}{2}\div 3\frac{3}{4}$

First of all we will convert mixed fractions into improper fractions.

$25\frac{1}{2}\Rightarrow \frac{25\times 2+1}{2}=\frac{50+1}{2}=\frac{51}{2}$

$3\frac{3}{4}\Rightarrow \frac{3\times 4+3}{4}=\frac{12+3}{4}=\frac{15}{4}$

$\frac{51}{2}\div \frac{15}{4}$

Now we will convert our division problem into multiplication problem by flipping the 2nd fraction as:

$\frac{51}{2}\times \frac{4}{15}$

Cancel out common factors:

$\frac{17}{1}\times \frac{2}{5}$

$\frac{17\times 2}{1\times 5}$

$\frac{34}{5}=6\frac{4}{5}$

Therefore, the tree is $6\frac{4}{5}$ is taller now than it was when the school first opened and option A is the correct choice.

Factor the polynomial by its greatest common monomial factor.

inna [77]

Answer:

$5 {y}^{2} (4 {y}^{4} - 3 {y}^{2} + 8)$

Step-by-step explanation:

We want to factor the common monomial out of :

$20 {y}^{6} - 15 {y}^{4} + 40 {y}^{2}$

The greatest common monomial fact is

$5 {y}^{2}$

We factor to get:

$5 {y}^{2} (4 {y}^{4} - 3 {y}^{2} + 8)$

The expression in the parenthesis has no common factor again since we factored the greatest common factor.

Please solve this question?

Alchen [17]

Given,

$\lim_{x}^{a}\dfrac{x^{2/3}-a^{2/3}}{x-a}$

We can use L'Hopital's Rule to get,

$\lim_{x}^{a}\dfrac{2}{3-\sqrt[3]{x}}$

Now plug in a,

$\boxed{\dfrac{2}{3-\sqrt[3]{a}}}$

Hope this helps.
