Answer:

x=-17

Step-by-step explanation:

<em>Original</em><em> </em><em>Equation</em><em>;</em>

<em>x</em><em>+</em><em>1</em><em>2</em><em>=</em><em>-</em><em>5</em>

<em>The</em><em> </em><em>1</em><em>2</em><em> </em><em>will</em><em> </em><em>cross</em><em> </em><em>the</em><em> </em><em>equal</em><em> </em><em>sign </em><em>so</em><em> </em><em>it </em><em>will</em><em> </em><em>become</em><em> </em><em>-</em><em>1</em><em>2</em><em>. </em><em>So</em><em> </em><em>it's</em><em> </em><em>going </em><em>to</em><em> </em><em>be</em><em>;</em>

<em>x</em><em>=</em><em>-</em><em>5</em><em>-</em><em>1</em><em>2</em>

<em>There </em><em>are</em><em> </em><em>two negative </em><em>number</em><em> </em><em>so</em><em> </em><em>you </em><em>add</em><em> </em><em>them</em><em> </em><em>and</em><em> </em><em>when</em><em> </em><em>you </em><em>add</em><em> </em><em>them</em><em> </em><em>it</em><em> </em><em>would</em><em> </em><em>still</em><em> </em><em>be</em><em> </em><em>negative</em><em>.</em><em> </em><em>And</em><em> </em><em>you </em><em>would</em><em> </em><em>have </em><em>to</em><em> </em><em>add</em><em> </em><em>them </em><em>because </em><em>when</em><em> </em><em>there </em><em>are</em><em> </em><em>two</em><em> </em><em>negative</em><em> </em><em>numbers</em><em> </em><em>without </em><em>any</em><em> </em><em>other</em><em> </em><em>sign </em><em>you </em><em>will</em><em> </em><em>have </em><em>to </em><em>add</em><em> </em><em>so</em><em> </em><em>it's </em><em>going</em><em> </em><em>to </em><em>be</em><em>;</em>

<em>x</em><em>=</em><em>-</em><em>1</em><em>7</em>

<em>This </em><em>is </em><em>the </em><em>final</em><em> </em><em>answer</em><em>!</em><em>!</em><em>!</em>

Solve system of equations:<br> 4l + 8m = 40<br> 5l + 2m = 28<br> Please show steps!
ziro4ka [17]
Answer:

l = 9/2 or 4.5

m = 11/4 or 2.75

Step-by-step explanation:

4l + 8m = 40

8m = 40 - 4I

m = 5 - 0.5l

5l + 2m = 28

5l + 2(5 - 0.5l) = 28

5l + (10 - l) = 28

4l + 10 = 28

4l = 18

l = 18/4 or 9/2

l = 4.5

4l + 8m = 40

4(4.5) + 8m = 40

18 + 8m = 40

8m + 18 = 40

8m = 22

m = 22/8

m = 2.75

In ΔUVW, the measure of ∠W=90°, UV = 4.1 feet, and VW = 1.9 feet. Find the measure of ∠V to the nearest tenth of a degree.
Lynna [10]

Answer:

Measure of angle V = 62.4°.

Step-by-step explanation:

Given information : In ΔUVW, m∠W=90°, UV = 4.1 feet, and VW = 1.9 feet.

We need to find the measure of ∠V to the nearest tenth of a degree.

In a right angled triangle

\cos \theta = \dfrac{adjacent}{hypotenuse}

Since m∠W=90°, so ΔUVW is a right angle triangle.

\cos (\angle V) = \dfrac{VW}{UV}

\cos (\angle V) = \dfrac{1.9}{4.1}

Taking cos inverse on both sides.

\angle V= \cos ^{-1}(\dfrac{1.9}{4.1})

\angle V=62.39233194

\angle V\approx 62.4

Therefore, the measure of angle V is 62.4°.
