Lelu [443]

We are given coordinates of the school located at a point (9,-1).

Library is located 5 blocks south and 4 blocks west .

According to coordinate axes, south is downward and west is on left side.

So, we need to move 5 units down of 9.

<em>5 units down of 9 would be 9-5 = 4.</em>

And then <em>4 blocks west that mean -1 -4 = -5.</em>

<h3>Therefore, coordinate of the library is located at the point (4,-5).</h3>

<h3>Answer: addition property of inequality</h3>

================================================

Explanation:

These are the steps to focus on

step 3: -6x - 8 < -2

step 4: -6x < 6

The move from the third step to the fourth step has us adding 8 to both sides. Therefore, we use the addition property of inequality.

That property has four forms

If $a > b$ then $a + c > b+c$
If $a < b$ then $a+c < b+c$
If $a \ge b$ then $a + c \ge b+c$
If $a \le b$ then $a+c \le b+c$

It's similar to the idea of starting with a = b, then adding c to both sides to get a+c = b+c

We add the same thing to both sides to keep things balanced.

Must include an explanation !!<br><br> solve for x

Ira Lisetskai [31]

Answer:

x=5

Step-by-step explanation:

Volume of a rectangular prism= $\frac{1}{2}$ b x l x h

Set up you equation

120= $\frac{1}{2}$ (4 x 12 x $x$ )

Multiply inside the parentheses

120= $\frac{1}{2}$ (48x)

Multiply by $\frac{1}{2}$

120=24x

Divide by 24 on both sides

5=x

Check you answer

Volume of a rectangular prism= $\frac{1}{2}$ b x l x h

Set up your equation

$\frac{1}{2}$ (12 x 5 x 4)

Multiply inside the parentheses

$\frac{1}{2}$ (240)

Multiply by $\frac{1}{2}$

V=120yd³
