ASAP solve 21x+6=300 10 points

Answers

Answer:

x = 14

Step-by-step explanation:

21x + 6 = 300

- 6 - 6

21x = 294

/ 21 / 21

x = 14

Answer:

The answer is x=14

Step-by-step explanation:

21x+6=300

21x+6-6=300-6

21x=294

To find x divide both sides by 21.

21x÷21=294÷21

If \triangle △RST is isosceles. find x then find m∠S.

due in 30 min plz help

X=

m∠S =

Answers

Answer:

s=32

Step-by-step explanation:

15x-31 = 9x+11

6x=42

x=7

2(63+11)= 2(74)= 148

180-148=32

Isosceles triangles have equal base angles.

The values of x and S are 7 and 32, respectively.

The base angles are given as: 15x - 31 and 9x + 11

So, we have:

[tex]\mathbf{15x - 31 = 9x + 11}[/tex]

Collect like terms

[tex]\mathbf{15x - 9x =31+ 11}[/tex]

[tex]\mathbf{6x =42}[/tex]

Divide both sides by 6

[tex]\mathbf{x =7}[/tex]

The measure of S is:

[tex]\mathbf{S = 180 - (15x - 31) - (9x + 11)}[/tex]

Substitute 7 for x

[tex]\mathbf{S = 180 - (15\times 7 - 31) - (9\times 7 + 11)}[/tex]

[tex]\mathbf{S = 180 - (74) - (74)}[/tex]

[tex]\mathbf{S = 32}[/tex]

Hence, the values of x and S are 7 and 32, respectively.

Sabeena’s pen measures 144 millimeters long. Her pencil measures 18 centimeters long. How many centimeters longer is Sabeena’s pencil than her pen?

Enter the correct answer in the box.

Answers

Answer:

3.6 cm or 36mm

Step-by-step explanation:

So we know that there are 10 millimetres in a centimetre. So we can convert the 18cm into millimetres to make it easy to subtract

18cm*10=180mm

now take the pencil length subtracted by the length of the pen.

180mm-144mm=36mm

now if you want the answer in cm, convert it by dividing the answer by 10

36/10=3.6cm

Hope This Helps :)

Answer:3.6 cm

3(2x -5)= 1
And explain

Answers

Answer:

x = 8/3

Step-by-step explanation:

distribute the 3 with everything in the parantheses

3(2x-5) --> 6x -15 = 1

move the 15 to the right side of the equation

6x = 16 and then divide by 6

x = 8/3

Answer:

x = 8/3

Step-by-step explanation:

3 ( 2x - 5 ) = 1

→ Expand out bracket

6x - 15 = 1

→ Add 15 to both sides to isolate 6x

6x = 16

→ Divide both sides by 6 to isolate x

x = 8/3

Andrew has already played 32 minutes on his video game this morning and wants to play an additional 15 minutes on each of x games after school today. Which equation can be used to find y, the total minutes Andrew will play video games today?

Answers

Given :

Andrew has already played 32 minutes on his video game this morning and wants to play an additional 15 minutes on each of x games after school today.

To Find :

Which equation can be used to find y, the total minutes Andrew will play video games today.

Solution :

Number of minutes he play after school time, n = 15x .

Number of minutes already played, c = 32 .

So, total number of minutes he play games for today is :

y = n + c

y = 15x + 32

Therefore, equation which is useful to find number of minutes video game played per day is y = 15x + 32 .

Mark sold 218 tickets for the school play and made $1,363. Adult tickets are $8 and
student tickets are $5. How many adult tickets did Mark sell?

Answers

Answer: 91

Step-by-step explanation:

Let adults tickets be a

Let students ticket be b.

The information in the question can be presented as an equation as:

a + b = 218 .......... i

8a + 5b = 1363 ......... ii

Multiply equation i by 5

Multiply equation ii by 1

5a + 5b = 1090 ........ iii

8a + 5b = 1363 ....... iv

Subtract iii from iv

3a= 273

a = 273/3

a = 91

Number of adult's ticket sold = 91

For the first picture shown and other pictures that look like it, take 180 and subtract the known value from it. Thats your answer

If it shows u an x like the top right one, subtract 360 with the known values and solve. If its one like the middle bottom one, subtract 90 by the known values.

A boat is located a sea level. A scuba diver is 80 feet along the surface of the water from the boat and 30 feet below thw water surface. A fish is 20 feet along the horizontal plane from the scuba diver and 10 feet below the scuba diver. What is the slope between the scuba diver and fish?

Answers

Given :

A boat is located a sea level. A scuba diver is 80 feet along the surface of the water from the boat and 30 feet below the water surface.

A fish is 20 feet along the horizontal plane from the scuba diver and 10 feet below the scuba diver.

To Find :

The slope between the scuba diver and fish.

Solution :

Horizontal distance between diver and fish is 20 feet.

Fish is 10 feet below the scuba diver.

Slope between scuba diver and fish is :

[tex]tan\ \theta = \dfrac{10}{20}\\\\tan\ \theta = 0.5[/tex]

Therefore, the slope between the scuba diver and fish is 0.5 .
