Answer 1

Answer:

1. 15 (A)

2. 12 (G)

Step-by-step explanation:

1. We can make an equation out of this...

3x+3=48

x is the age of Geoff which is what we are trying to find out

We have to add 3 to both sides of the equation

3x+3=48

-3 -3

________

we end up with 3x=45

we then have to divide 3 by both sides because its the opposite of

multipling

3x=45

_____

we get x=15

2. We can write a problem statement

(2 x 9)-6=?

multiply 2 and 9 FIRST

18-6=?

your answer is 12

Your Welcome! Have a great rest of your day! :)

Using ƒ(x) = 2x + 7 and g(x) = x − 3, find ƒ(g(x)).

Answers

Answer:

We get [tex]\mathbf{f(g(x))=2x+1}[/tex]

Option A is correct answer.

Step-by-step explanation:

We are given:

[tex]f(x) = 2x + 7 \\g(x) = x - 3[/tex]

We need to find f(g(x))

f(g(x)) can be found by putting x in f(x) equal to g(x)

Now, finding f(g(x))

[tex]f(x)=2x+7\\Put\:x=x-3\\f(g(x))=2(x-3)+7\\f(g(x))=2x-6+7\\f(g(x))=2x+1[/tex]

So, we get [tex]\mathbf{f(g(x))=2x+1}[/tex]

A cell-phone company charges $10 per month plus $0.10 per minute. HoW 1 point many min. can Tori use if she has budgeted $30 per month for her cell- phone bill? *

Answers

200 minutes,

Step-by-step explanation:

So, 10 dollars is the monthly charge, and she has a budget of 30 dollars

30-10 is 20

So she will have 20 dollars to use on minutes

.10 cents per minute, .10 times 20 is 2, and .10 times 200 is 20

Answer:

200 minutes

Step-by-step explanation:

ok so subtract 10 from 30 because she has to spend that.

she now has 20 so see how many times 0.10 goes into 20.

Twelve of the 20 students in Mr. Skinner’s class brought lunch from home. Fourteen of the 21 students in Ms. Cho’s class brought lunch from home. Siloni is using two 15-section spinners to simulate randomly selecting students from each class and predicting whether they brought lunch from home or will buy lunch in the cafeteria.

If each spinner is divided into 15 congruent sectors, how does the spinner representing Mr. Skinner’s class differ from the spinner representing Ms. Cho’s class?
One more sector of the Skinner-class spinner will represent bringing lunch from home.
One fewer sector of the Skinner-class spinner will represent bringing lunch from home.
Two more sectors of the Skinner-class spinner will represent bringing lunch from home.
Two fewer sectors of the Skinner-class spinner will represent bringing lunch from home.

Answers

Answer:

HOPE THIS HELPS

Step-by-step explanation:

Number of students in Mr.Skinner's class who brought lunch from home if there are 20 students in the class=12

Fraction of students who brought lunch from home in Mr. Skinner's class=

Number of students in Ms. Cho's class who brought lunch from home if there are 21 students in the class=14

Fraction of students who brought lunch from home in Ms. Cho's class=

As Siloni is using two 15-section spinners to simulate randomly selecting students from each class and predicting whether they brought lunch from home or will buy lunch in the cafeteria.

Number of Congruent sectors in each Spinner=15

So, if we represent students from Mr. Skinner's class who brought lunch from home in Spinner having 15 congruent Sectors =

So, if we represent students from Mrs. Cho's class who brought lunch from home in Spinner having 15 congruent Sectors =

Mr Skinner class +1 = Mr's Cho's Class

So Ms Cho's class =One more sector of the Skinner-class spinner will represent bringing lunch from home.

Option A which is One more sector of the Skinner-class spinner will represent bringing lunch from home represents Ms Cho's Class.
