Answer:

-13 + 22 = 9

Step-by-step explanation:

This should be simple if I am not overthinking this

If the temperature started at -13 degrees F and rose to 9 degrees F

you just need to add 13 to 9 to find the "space" or difference betweent he numbers

When you do this you get 22

So its -13 + 22 = 9

-x - 163 = 12x + 84

Inessa05 [86]

Answer:

X = -19

Step-by-step explanation:

Add x to both sides to get rid of -x

-163 = 13x + 84

subtract 84 from both sides

-247 = 13x

divide by 13

x = -19

The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−3, 2) and goes to

emmainna [20.7K]

Answer

Find out the the total length of the walking trail .

To prove

Formula

$Distance\ formula = \sqrt{(x_{2} - x_{1})^{2} +( y_{2} - y_{1})^{2}}$

As given

The trail starts at R(−3, 2) and goes to S(2, 2) and continues to T(2, −5).

$RS = \sqrt{(2-(-3))^{2} +( 2 - 2)^{2}}$

$RS = \sqrt{( 2 - (-3))^{2}}$

$RS = \sqrt{5^{2}}$

$RS = \sqrt{25}$

$\sqrt{25} = 5$

RS = 5 units

As given

S(2, 2) and continues to T(2, −5).

Now

$ST = \sqrt{(2-2)^{2} +( -5-2 )^{2}}$

$ST = \sqrt{( - 7)^{2}}$

$ST = \sqrt{49}$

$\sqrt{49} = 7$

ST = 7 units

Therefore

Total length of the trail = RS + ST

= 5 units + 7 units

= 12 units

Therefore the total length of the trail is 12 units.
