-5-r=1+2r
Add your r to both sides of the equal sign
-5=1+3r
Subtract your 1 on both sides of the equal sign
-6=3r
Divide your 3 on both sides of the equal sign
-2=r
HOPE THIS HELPS YOU! ^_^

Answer:

Step-by-step explanation:

it's a right triangle so we can use the pythagorean theorem to find h

pythagorean theorem: a^2+b^2=c^2

h^2+361=441

h^2=80

h≈ 8.9ft

Let u = <-9, 4>, v = <8, -5>. Find u - v. <br> URGENT

Pie

To subtract vectors, you simply have to subtract correspondent coordinates.

So, if you have

$u = \langle u_1,\ u_2,\ldots u_n\rangle ,\quad v = \langle v_1,\ v_2,\ldots v_n\rangle$

the subtraction is simply

$u-v = \langle u_1-v_1,\ u_2-v_2,\ldots u_n-v_n\rangle$

So, in your case, we have

$\langle-9,4\rangle-\langle 8,-5\rangle=\langle -9-8, 4+5\rangle=\langle -17,9\rangle$

Find the sum.<br>(w - 2.4) + (1 - 0.5w)

vodka [1.7K]

The sum of the given expression { (w - 2.4) + (1 - 0.5w) } is 0.5w - 1.4.

<h3>What is the sum of the given expression?</h3>

Given the expression in the question;

(w - 2.4) + (1 - 0.5w)

Remove the parenthesis

w - 2.4 + 1 - 0.5w

Collect like terms and simplify

w - 2.4 + 1 - 0.5w

w - 0.5w - 2.4 + 1

1w - 0.5w - 2.4 + 1

0.5w - 1.4

Therefore, the sum of the given expression { (w - 2.4) + (1 - 0.5w) } is 0.5w - 1.4.
