Mathematics High School

The mean of 19 students is 126cm.
Another student joins the group and the mean becomes 128cm.
What is the height of the new student?

Answers

Answer 1

Answer: 166 cm

Step-by-step explanation:

x / 19 = 126

* 19 * 19

x = 2394

(2394 + y) / 20 = 128

* 20 * 20

2394 + y = 2560

- 2394 - 2394

y = 166

Answers

Answer:

-16 =n

Step-by-step explanation:

Let n= number

4n -21 = 6n +11

Subtract 4n from each side

4n-4n -21 = 6n-4n +11

-21 = 2n+11

Subtract 11 from each side

-21-11 = 2n

-32 = 2n

Divide by 2

-32/2 = 2n/2

-16 =n

Answer : -16 =n

Step-by-step explanation:

Let n= number

4n -21 = 6n +11

Subtract 4n from each side

4n-4n -21 = 6n-4n +11

-21 = 2n+11

Subtract 11 from each side

-21-11 = 2n

-32 = 2n

Divide by 2

-32/2 = 2n/2

-16 =n

Step-by-step explanation:

For this problem you just plug in numbers for the answer. Typically you will see functions in the f(x) format but this time you're given f(70) which means that 70=x so you just plug in 70 for the x on the right side of the equation and get 198.425.

Step-by-step explanation:

[tex]8 - (5 - 9x) = 7(1 - x) \\ 8 - 5 + 9x = 7 - 7x \\ 3 + 9x = 7 - 7x \\ 3 + 9x + 7x = 7 \\ 16x = 7 - 3 \\ 16x = 4 \\ x = 4 \div 16 \\ = \frac{1}{4} [/tex]

1. Which function is exponential? Write the function
(Exponential form is y=a(b)^x)
2.Which function is linear? Write the function
( linear y=mx+b)

Answers

Answer:

Easy way to distinguish:

Linear function forms a AP and exponential function forms a GP

We see f(x) is series of:

8, 14, 20, 26, 32This is a AP with common difference of 6 and the first term of 8

g(x) is series of:

4, 12, 36, 108, 324This is a GP with common ratio of 3 and the first term of 4

1. g(x) is exponential function:

g(x) =4*3ˣ

2. f(x) is linear function:

f(x) = 6x + 8

Answers

Answer:

y = 27/6

Step-by-step explanation:

3/2x - 6 = -9/2x + 21

12/2x = 27

6x = 27

Since both are y, you know the values are equal to each other.
3/2x - 6 = -9/2x + 21
3/2x = -9/2x + 27
Get rid of fraction (multiply by 2)
3x = -9x + 54
12x = 54, x = 4.5
Plug 4.5 into any equation as x
y = 3/2(4.5) - 6
y = 6.75 - 6 = 0.75

Solution: y = 0.75 or 3/4
