The graph shows the proportional relationship between rainfall during the growing season and seasonal growth of a type of plant. What does the point ​(​8,6​) ​represent? If the plants grew 12 mm one​ season, how much rain​ fell?

Answers

Answer/Step-by-step explanation:

✔️The point (8, 6) represents seasonal plant growth of 6 mm with 8 cm of rainfall during the growing season.

✔️To determine how much rain fell if the plants grew 12 mm one season, find the value of x (rainfall) when y (plant growth) = 12.

From the graph, when y = 12, x = 16.

This means that when the plant grew 12 mm, 16 cm of rainfall was recorded.

Therefore:

If the plants grew 12 mm one season, 16 cm rainfall fell.

If \triangle △RST is isosceles. find x then find 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.

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 .

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

Answer: ight bet i gotchu its x=−4

Step-by-step explanation:

Let's solve your equation step-by-step.

7x−7=3x−23

Step 1: Subtract 3x from both sides.

7x−7−3x=3x−23−3x

4x−7=−23

Step 2: Add 7 to both sides.

4x−7+7=−23+7

4x=−16

Step 3: Divide both sides by 4.

Santa has many toys to deliver on Elm Street. If there are 48 kids that live on Elm
Street and 12 of them are boys what is the ratio of girls to boys?

Answers

Answer: 3 : 1

Step-by-step explanation:

We know that there are 48 kids in Elm street.

12 of them are boys, then the number of girls will be:

48 - 12 = 36

So there are 12 boys and 36 girls.

Then the ratio of girls to boys is 36:12

We can divide both numbers by the same number and we will get an equivalent ratio, if we divide by 12 in both sides, we have:

36/12 : 12/12

3 : 1

Then the ratio is 3 to 1.
