Calculate the mean of Bryanna's test scores if she has scored 75, 97, and 92 so far this
semester
A 284
o
B
88
c. 75
D

Answers

Answer 1
Answer:  88

Work Shown:

Add up the values

75+97+92 = 264

Then divide by 3 since there are 3 scores

264/3 = 88

You can write this all as one step

(75+97+92)/3 = 88

So in short, you add the scores and then divide by the number of scores.

Stephen, Gavin and Jim share some sweets in the ratio 3:1:2. Stephen gets 24 sweets. How many sweets are there altogether?

Answers

Answer:

Step-by-step explanation:

Stephen : Gavin : Jim

3 : 1 : 2

We can say that this means the total amount of sweets get split between the 3 of them into 6 equal parts ( 3 + 1 + 2).

If Stephen gets 24 sweets, this means

3 parts = 24

So to find 1 part, divide 24 by 3.

1 part = 8 sweets

Now we can find the total by multiplying this by 6.

6 parts = 8 x 6 = 48 sweets.

y=11x+6y=11x+6 what is the x and y intercept

Answers

Answer:

y = 1 [ y intercept (0,1) ]

x = -5/11 [ x intercept : (-5/11,0) ]

Explanation:

First split this compound equation into two seperate ones:

y = 11x + 6y = 11x + 6 →

{ y = 11x + 6y → -5y = 11x → [ y = -11/5x ]

[ y = 11x + 6 ] }

________

Then find the x point of intersection by substitution.

y = -11/5x → y = 11x + 6

-11/5x = 11x + 6

-11/5x - 11x = 6

-66x/5 = 6

-66x = 30

-11x = 5

x = 5/-11

x = -5/11

_______

Then find the y point of interesection by substituting the x solution in one of the equations.

x = -5/11 → y = -11/5x

y = -11/5(-5/11)

y = 55/55

y = 1

The x-intercept is x = - 6/11.

The y-intercept is y = 6.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

y = 11x + 6

Now,

The x-intercept means y = 0.

So,

y = 11x + 6

0 = 11x + 6

11x = -6

x  = - 6/11

The y-intercept means x = 0.

y = 11x + 6

y = 0 + 6

y = 6

Thus,

The x-intercept is x = - 6/11.

The y-intercept is y = 6.

5 ( 3x - 2) = 4 ( 2x + 1)

Answers

Answer:

15x-2=8x+1

13x=9x

i think that's correct im not sure but i hope to help u :)

5(3x-2)=4(2x+1)
(15x-10)=(8x+4)
7x-10=4
7x=14
X=2
Explanation:
I multiplied everything inside the parenthesis by the number on the outside, making the equation 15x-10=8x+4, then I combined like terms, so I subtracted 8x on both sides and added 10 to each side, making the equation 7x=14, this means that 14/7 and 7/7 is the last step, which leaves you with the answer of x=2
