Answer:

see below

Step-by-step explanation:

We can just add up all of these fractions:

2 1/8 + 7/8 = 2 8/8 = 3

8 5/8 + 4/8 = 8 9/8 = 9 1/8

3 + 9 1/8 = 12\frac{1}{8}

HELP ME PLEASE!! ASAP!!
Levart [38]
The total area is given by:
 A1 = (300) * (500)
 A1 = 150000 feet ^ 2
 The area occupied by 5 people is:
 A2 = (5) * (5)
 A2 = 25 feet ^ 2
 Then, we can make the following rule of three:
 5 --------> 25
 x --------> 150000
 Clearing x we have:
 x = (150000/25) * (5)
 x = 30000

Find the value of c that completes the square for x2−15x+c
meriva

Answer:

The value of <em>c</em> is \frac{225}{4}.

Step-by-step explanation:

The perfect square of the difference between two numbers is:

(x-y)^{2}=x^{2}-2xy+y^{2}

The expression provided is:

x^{2}-15x+c

The expression is a perfect square of the difference between two numbers.

One of the number is <em>x</em> and the other is √<em>c</em>.

Use the above relation to compute the value of <em>c</em> as follows:

x^{2}-15x+c=(x-\sqrt{c})^{2}\\\\x^{2}-15x+c=x^{2}-2\cdot x\cdot\sqrt{c}+c\\\\15x=2\cdot x\cdot\sqrt{c}\\\\15=2\cdot\sqrt{c}\\\\\sqrt{c}=\frac{15}{2}\\\\c=[\frac{15}{2}]^{2}\\\\c=\frac{225}{4}

Thus, the value of <em>c</em> is \frac{225}{4}.

Tcecarenko [31]

Answer:

x - 2

Step-by-step explanation:

2x - 1 + 4x - 11

First, you want to combine like terms.

We can see that the one and eleven can go together, so add them together.

2x + 4x - 12

The reason that we made one, and eleven, negative twelve, is because they are both being subtracted from the numbers before that.

6x - 12

We added the 2x, and the 4x together to make 6x.

Another way to write this would be x - 2, because you can simplify it by dividing it by 6.
