Answer: 3(x+4)=x+18

Step-by-step explanation: Break down the problem. It says three times the sum of a number and 4. You have to add the number and 4 first. Since you're multiplying by 3, put the sum of a number and 4 in parentheses. This equals the same as eighteen more than the number. It set up how it sounds. Add 18 to the number.

Sin=oposite side/hyptoonuse
Cos=adjacent side/hypotonuse
Tan=oposite side/hypotonuse

oposite side is the side oposite the angle
adjacent side is the side touching the angle that isn't the hypotonuse
hypotonuse is longest side





1.
first solve for hypotonuse using a²+b²=c²
hypotonuse=13
sinA=12/13
cosA=5/13
tanA=12/5
sinB=5/13
cosB=12/13
toa=5/12


2. the missing side is 8
sinD=15/17
cosD=5/17
tanD=15/5=3
sinE=5/17
cosE=15/17
tanE=5/15=1/3


3. missing side is 25
you should be able to do this
sinG=7/25
do the rest


4.
missing side is 6
sinJ=6/10=3/5
do the rest

Lanie is saving money to buy a car. She saved $772 so far. She earns $157 every month. How many months until Lanie has saved $2,
ser-zykov [4K]

Answer:

<u>9</u> months until Lanie has saved $2,176.

Step-by-step explanation:

Given:

Lanie is saving money to buy a car. She saved $772 so far.

She earns $157 every month.

Now, to find the months until Lanie has saved until $2,176.

Let the number of months Lanie has saved be x.

She earns per month = $157.

She saved so far = $772.

<em><u>According to question:</u></em>

So, to get the months lanie has saved until $2,176 we write an equation.

157x+772=2176

<em>Subtracting both sides by 772 we get:</em>

157x=1404

<em>Dividing both sides by 157 we get:</em>

x=8.95<em />

<u><em>So, the number of months nearest to the month = 9.</em></u>

Therefore, 9 months until Lanie has saved $2,176.
