Step-by-step explanation:
= f(g(x)) = g(f(x))
= f(x - 3) = g(5x)
= 5(x- 3) : 5x - 3
: 5x - 15

x – 3.5 = 14.9, x = ?
Answer:
x = 18.4
Step-by-step explanation:
x - 3.5 = 14.9
Add 3.5 to both sides.
x = 14.9 + 3.5
x = 18.4
Answer:
x = 18.4
Step-by-step explanation:
x - 3.5 = 14.9
+ 3.5 +3.5

3/7 of the students in a school are girls. If there are 64 boys find how many girls there are
Answer:
About 28
Step-by-step explanation:
Answer:90
Step-by-step explanation:Hi.
Here is your answer---
Let the number of Students in a school be x.
Thus,Number of Girls = 3/7 of the total Students
= 3/7 of x
= 3x/7
We know,
Number of Boys + Number of Girls = Total Students.
64 + 3x/7 = x
64 = x - 3x/7
64 = (7x - 3x) /7 [Taking L.C.M.]
64 × 7 = 4x
x = 60 × 7
x = 420
Total number of Students in a school is 420.
Thus, Number of Girls = 3/7 × x
= 3/7 × 420
= 90
Thus, the number of Girls in a school is 90.

Answer:
n<-0.6
Step-by-step explanation:
7.2>0.9(n+8.6)
8>n+8.6
-0.6>n
n<-0.6
So there would be an open circle at the point -0.6 (because the "less than" sign shows that -0.6 is not included), and then an arrow pointing left to show solutions that are less than -0.6
I will assume you know what buttons to press.
Answer:
Step-by-step explanation:
7.2>0.9(n+8.6)
n< -0.6
(-∞,-0.6)
open circle on -0.6 and go to the left

You decide to join a tennis class. The initial entrance fee is
$100, and a $10 fee every month you want to take the class.
How much will it cost for five months?
Given :
Initial entrance fee of tennis class, E = $100 .
Fee of every month, F = $10 .
To Find :
How much will it cost for five months.
Solution :
Let, number of months are n and cost of class is y.
So, linear equation is given by :
y = 10n + 100 ...1)
To know the cost of 5 month, putting value of n = 5 in equation 1) we get :
y = ( 10×5) + 100
y = 50 + 100
y = $150
Therefore, the cost of five month fee in tennis class is $150.
Hence, this is the required solution.

Can someone show me how do I do this please?
Answer:
the awnser is c
Step-by-step explanation:
A- 100:1 would mean it is a 10000% markup
B- 1:100 lower than b so eliminate
C- 2:1 So a is double the amount of b so it's 100%
D- 1:2 B is 100% of a so it's flipped, not what question is asking for
So process of elimination shows that C is the correct awnser
Thomas observed that his friend blinked an average of three times every 15 seconds.
How many times should his friend blink in 65 second?
Answer:
13 blinksStep-by-step explanation:
Step one:
given
number of blinks= 3
time taken to blink=15 seconds
the rate of blink is given as
rate= number of blinks/time taken
rate= 3/15
rate= 1/5 blinks per second, 0.2 blinks per second
Step two:
hence for a 65 second period, the number of blinks is
rate=number of blink/time
0.2=number of blink/9=65
cross multiply we have
number of blink=0.2*65
number of blink=13 blinks

Step 1: Define systems
y = x + 1
y = 1/2x + 3
Step 2: Solve for x
Substitute in y: x + 1 = 1/2x + 3Subtract 1/2x on both sides: 1/2x + 1 = 3Subtract 1 on both sides: 1/2x = 2Divide both sides by 1/2: x = 4Step 3: Solve for y
Define original equation: y = x + 1Substitute in x: y = 4 + 1Add: y = 5Step 4: Graph
