koban [17]3 years ago

<em>Answer,</em>

<em><u>S = -16</u></em>

<em>Explanation,</em>

<em><u>Step 1: Simplify both sides of the equation.</u></em>

<em>13 + 11s = − 15 + 8s − 20</em>

<em>13 + 11s = − 15 + 8s + − 20</em>

<em>11s + 13 = (8s) + (</em><em><u>− 15</u></em><em> + </em><em><u>− 20</u></em><em>) </em><em>(Combine Like Terms)</em>

<em>11s + 13 = 8s + − 35</em>

<em>11s + 13 = 8s − 35</em>

<em><u>Step 2: Subtract 8s from both sides.</u></em>

<em>11s + 13 − 8s = 8s − 35 − 8s</em>

<em>3s + 13 = − 35</em>

<em>Step 3: Subtract 13 from both sides.</em>

<em>3s + 13 − 13 = − 35 − 13</em>

<em>3s = − 48</em>

<em><u>Step 4: Divide both sides by 3.</u></em>

<em>3s/3 = −48/3</em>

<em>s = -16</em>


<u><em>Hope this helps :-)</em></u>

Find the cosine of ∠Y.
OleMash [197]

Answer:

\frac{33}{65}

Step-by-step explanation:

Cosine is equal to the ratio of the adjacent side to the hypotenuse.

In this case, the adjacent side measures 33 units and the hypotenuse measures 65.

So cos(y)=\frac{33}{65}.

. An amusement park bought some arcade games that cost $2,000 each and photo booths that cost $3,200 each. A total of 22 of both
geniusboy [140]

Answer:

14 arcade games and 8 photobooths were purchased

Step-by-step explanation:

x will represent the number of arcade games

y will represent the number of photobooths

We know that 22 total machines were bought which means that x+y=22

We also know that the total was 53600 which means that 2000x+3200y=53600

We can use substitution to solve this

x+y=22

x-22= -y

-x+22=y

Then plug this in for y in the next equation

2000x+3200(-x+22)=53600

Solve this and get x=14

Then plug in x=14 into any equation (I will choose the x+y one because that's easiest to solve)

14+y=22

this means y=8

This means that 14 arcade games and 8 photobooths were purchased

I double checked the math on desmos and it is correct

a ladder, 24m long, leans against a vertical wall and touches it 18m above the ground. How far is the foot of th ladder from the
Svet_ta [14]

Answer:

15.87 m

Step-by-step explanation:

Length of ladder = hypotenus = 24 m

Height, opposite = 18m

Foot of ladder from the wall = x

Using Pythagoras rule :

Hypotenus² = opposite² + Adjacent²

x² = hypotenus² - opposite²

x² = 24² - 18²

x² = 576 - 324

x² = 252

x = √252

x = 15.87 m
