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

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.

PLEASE HELPPPXPDPD. If -5c+6=-69, what is the value of 6c-15?

crimeas [40]

Answer: 75

Step-by-step explanation:

To find the value of 6c-15, we first want to finc the value of c. Once we find c, we can plug it in and solve.

-5c+6=-69 [subtract both sides by 6]

-5c=-75 [divide both sides by -5]

c=15

Now that we have the value of c, we can plug it in and solve.

6(15)-15 [multiply]

90-15 [subtract]

75

The value is 75.

Answer:

c (all real numbers)

Step-by-step explanation:

The first inequality has the solution ...

3 + v ≤ -4

v ≤ -7 . . . . . . . subtract 3 from both sides

__

The second inequality has the solution ...

-2v ≤ 14

v ≥ -7 . . . . . . . divide by -2. Division by a negative reverses the inequality

__

So, the solution to the compound ...

v ≤ -7 or -7 ≤ v

is every number — <em>all real numbers</em>. The graph of that is the entire number line, as in choice C.
