Hello,

The correct answer is -1.

(Drawing the number line)

Draw a number line on a piece of paper. Write a 0 in the middle. Then on the left side on the number line write the numbers -1 to -5. On the right side of the number line draw the numbers 1 - 5.

-5 -4 -3 -2 -1  0  1  2  3  4  5

(Finding the answer)

On the number line start at -5 and then move 4 spaces to your right and you will land on the number -1.

(Answer)

(-5) + 4 = -1

Hope this helps!!!!!! (:

If you have a number line, you’ll see that -5 is 5 spaces behind zero. By adding 4, you move 4 spaces forward to -1. Therefore, -1 would be your answer.

The floor of a triangular room has an area of 32 1/2 sq.m. If the triangle’s altitude is 7 172 m, write an equation to determine
sineoko [7]

Answer:

\frac{(2)A}{h} =b

b=0.00906m

Step-by-step explanation:

Hello! To solve this exercise we must remember that the area of ​​any triangle is given by the following equation

A=\frac{bh}{2}

where

A=area=32.5m^2

h=altitude=7172m

b=base

Now what we should do take the equation for the area of ​​a rectangle and leave the base alone, remember that what we do on one side of the equation we must do on the other side to preserve equality

A=\frac{bh}{2} \\\frac{2}{h} A=\frac{bh}{2} \frac{2}{h} \\

\frac{A(2)}{h} =b

solving

\frac{2(32.5)}{7172} =0.0090[tex]\frac{A(2)}{h} =b\\b=0.00906m

Answer:

x<5

Open circle at 5  going to the left

x >1

Open circle at 1 going to the right

Step-by-step explanation:

7x -19 < 16

Add 19 to each side

7x -19 +19< 16+19

7x< 35

Divide by 7

7x/7 < 35/7

x<5

Open circle at 5  going to the left

9+3x>12

Subtract 9 from each side

9-9 +3x >12-9

3x >3

3x/3 >3/3

x >1

Open circle at 1 going to the right
