Please HELP. <br> 11x-2x+15=8+7+9x
ycow [4]

<u>Hello!</u> ✌.ʕʘ‿ʘʔ.✌

Okay, let's start by first combining like terms on the left side of the equal sign. (づ。◕‿‿◕。)づ

11x - 2x = 9x

Now we have 9x + 15 = 8 + 7 + 9x! <em><u>Wow! </u></em>(ノ◕ヮ◕)ノ*:・゚✧

Now let's look at the right side.

8 + 7? That's easy! 15!

<u>So now we have...</u>

9x + 15 = 15 + 9x

Hmm... these equations are the same! So they will have infinite solutions! ᕙ(⇀‸↼‶)ᕗ

But let's keep going ( ̄。 ̄)~zzz

<u>Subtract 15 from both sides:</u>

<u>9x + 15 (-15) = 15 (-15) + 9x</u>

9x = 9x

<u>Divide both sides by 9x:</u>

9x/9x = 9x/9x

0 = 0

So the answer is....

<u><em>Drum roll please!!!</em></u>

<u><em>Dun dun dun</em></u>

<u><em></em></u>

<u><em>Infinite solutions! Yay! O(≧▽≦)O</em></u>

Please help me find the answer and explain the process to find the answer of the problem appreciate it :)
Natalka [10]

Answer:

Total distance traveled is 67.653 miles

Step-by-step explanation:

Side a = 14 (miles traveled South)

Side b = 25 (miles traveled East)

side c = a^{2} + b^{2}

196 + 625 = c^{2}

821 = c^{2}

\sqrt{821} = \sqrt{c^{2} }

c = 28.653 (rounded to the nearest 1000th)

Now add the three sides to get the total distance:

14 + 25 + 28.653 = 67.653

Help me with number 15 and 16
loris [4]

Answer:

Problem 15)

$40.91

Problem 16)

12.446 cm^2

Step-by-step explanation:

Problem 15)

Gala.

12.8 * 1.35 = 17.28

Honeycrisp.

9 * 1.68 = 15.12

Fuji

7.4 * 1.15 = 8.51

17.28 + 15.12 + 8.51 = 40.91

Problem 16)

(area1) + (area2) + (area3) = (total area)

(1.25*4.38) + (1.36*2.15) + (1.14*3.55) = x

5.475 + 2.924 + 4.047 = x

12.446 = x
