9 - 6(x+1) = 2(x-4) + 27

Answers

Hey :)

1) Use the distributive property to multiply −6 by x + 1

9−6x −6 = 2(x−4) +27

2) Subtract 6 from 9 to get 3

3−6x =2(x−4) +27

3) Use the distributive property to multiply 2 by x−4

3−6x =2x−8 +27

4) Add −8 and 27 to get 19

3−6x = 2x +19

5) Subtract 2x from both sides

3−6x −2x = 19

6) Combine −6x and −2x to get −8x

3−8x = 19

7) Subtract 3 from both sides

−8x= 19−3

8) Subtract 3 from 19 to get 16

−8x = 16

9) Divide both sides by −8

x= 16/-8
​

10) Divide 16 by −8 to get −2

x=−2

Jose's school is selling tickets to a choral performance. On the first day of ticket sales
the school sold 3 adult tickets and 7 child tickets for a total of $132. The school took
in $141 on the second day by selling 4 adult tickets and 7 child tickets. What is the
price each of one adult ticket and one child ticket?

Answers

Step-by-step explanation:

let x be the price of the adult ticket and y the price of child ticket

so

3x+7y=132

4x+7y=141

from the first equation 7y=132-3x

lets replaxe this from the second equation

4x+(132-3x)=141

4x-3x=141-132

x=9

so knowing that 7y=132-3x

7y=132-3*9

7y=105

y=105/7=15

so finaly the adult ticket cost 9 dollars and child ticket cost 15 dollars

Jaime’s older brother and his three friends want to split the cost of lunch. They also want to leave a 15%–20% tip. How much should each person pay?

Answers

Answer:

First you have to split the cost of the meal and percentage so

$78.00 divided by 4 that's $19.50 each then after the 20% each would pay $23.40

Each person pay $23.4.

Given, from the fig the total cost of lunch without tip is $78.

Now, Jaime’s older brother and his three friends want to split the cost of lunch between them. So there is total 4 person.

Now each person have to pay [tex]\frac{78}{4} = $ 19.5[/tex]  dollars.

Further they decided to pay tip say 20% so, the amount of tip is 20% of $78.

On calculating amount of tip [tex]=\frac{20}{100} \times 78=15.6[/tex].

Tip is divided among them so per person has to pay tip [tex]=\frac{15.6}{4} =3.9[/tex] dollars.

So, the total amount each person has to pay [tex]=19.5+3.9=23.4[/tex] dollars.

Hence each person pay $23.4.

The perimeter of a rectangle is 36 m. If the length is three times the width, what is the length?

Answers

Answer:

13.5 meters

Step-by-step explanation:

As the rectangle has 4 sides and the length is three times the width, each pair of a long side and a short side has a perimeter of 18 meters. As the ratio is 3:1, there are 4 parts in 18 meters, and 18 divided by 4=4.5. As the length covers 3 parts, and there are 4.5 meters per part, 4.5x3=13.5. The length of the rectangle is 13.5 meters.

What is the relationship between length of side of triangle and their interior  angle ?

Relationship of sides to interior angles in a triangle

In any triangle:

The shortest side is always opposite the smallest interior angleThe longest side is always opposite the largest interior angle

According to the question

Side opposite to smallest ∠20° = OD

Side opposite to largest ∠110° = DE

Side opposite to intermediate ∠50° = OE

Now,

according to the relationship between length of side of triangle and their interior angle

The smallest side is opposite the smallest angle, and the longest is opposite the largest angle, then it follows that since a triangle only has three sides, the midsize side is opposite the midsize angle.

Therefore,

OD = smallest side

DE = Largest side

OE = intermediate side

Hence, The side with intermediate length is OE .
