Eighteen is six less than four times a number. (write and solve the equation - use x as your variable) *
Answer:
x = 6
Step-by-step explanation:
The given statement is "Eighteen is six less than four times a number".
Let the number be x.
ATQ,
18 = 4x-6
Taking like terms together,
18+6 = 4x
24 = 4x
x = 6
Hence, the value of x is 6.

Answer:
4.5
so I did 9 /2 = 4.5
Answer:
4.5 or 9/2 or 4 1/2
Step-by-step explanation:
You divide 9 by 2, to get 4.5 in number form. 9/2 for improper fraction form and 4 1/2 for whole number fraction.
Hiram takes an Uber from his house to the alrport. The Uber driver charges $3.50 initial fee plus
$7.25 per mile. Write the equation that can be used to find y, the total cost of the trip, If x
represents the number of miles in the trip? (Do not include $ in your equation).
Answer:
y = 7.25x + 3.50
The X coordinate of a point P on X axis is 4 and the y coordinate of a point Q on y axis is 3. Find the distance of PQ.
Answer:
5 units
Step-by-step explanation:
Since The X coordinate of a point P on X axis is 4 and the y coordinate of a point Q on y axis is 3 the points are
P (4 , 0) and Q(0 , 3)
The formula to calculate distance between two points
[tex]PQ=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\PQ=\sqrt{(0-4)^2+(3-0)}\\PQ=\sqrt{(4)^2+(3)^2}\\PQ=\sqrt{16+9} \\PQ=\sqrt{25} \\PQ=5\ units\ \\[/tex]
IMPORTANT!
As we take the square root of 25 we get two values +5 and -5 we always take the positive value because distance can never be negative.

Given: g(x) = Vx – 4 and h(x) = 2x – 8.
What is g(h(10))?
Answer:
g(h(10)) = 43
Step-by-step explanation:
Given: g(x) = 4x – 4 and h(x) = 2x – 8.
We are to find g(h(10))
First we need to get g(h(x))
g(h(x)) = g(2x-8)
Replace x in g(x) with 2x-8 as shown:
g(2x-8) = 4(2x-8)-4
g(2x-8)= 8x-32-5
g(2x-8) = 8x-37
Hence g(h(x)) = 8x-37
g(h(10)) = 8(10)-37
g(h(10)) = 80-37
g(h(10)) = 43
Hence g(h(10)) is 43
Jayden ran 9 laps in 27 minutes. How many minutes dose it take him to run 20 laps
Answer:
It would take him 60 minutes to run 20 laps.
Step-by-step explanation:
We can solve using proportions.
[tex] \frac{9 \: laps}{27 \: minutes} = \frac{20 \: laps}{x} \\ \\ \frac{540}{9} = \frac{9x}{9} \\ \\ 60 = x[/tex]
It would take him 60 minutes.
"A number x increased by 6, and then doubled."
A)
2x + 6
B
B)
2x - 6
2(x + 6)
D)
246 - x)
Answer:
(X + 6 ) ×2
It is given in the question that the no. is increased by 6 so if we take the no. as X the new no. formed is X + 6 now on doubling it the answer we get is. 2(X+6)
The correct algebraic expression is option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.
Given that : "a number x increased by 6, and then doubled," perform the operations in the correct order.
To represent the given scenario of "a number x increased by 6, and then doubled," required to follow the steps:
Step 1:
Let the number be x.
Increase the number x by 6:
x + 6.
Step 2 :
Double the result by multiply the expression:
(x + 6)2,
Remove brackets by BODMASS gives:
2* x + 2 *6
On multiplying gives:
2x+12
ON taking common factors 2 gives:
2(x+6)
Therefore, the correct expression is 2(x + 6).
Option C) 2(x + 6) matches the expression that represents the number x increased by 6, and then doubled.

What pair of points have a slope of -3/5
Answer:
(5,0) and (0,3) have a slope of -3/5
Step-by-step explanation:
Here, we want to state a pair of points that have a slope of -3/5
Mathematically, we can have the slope of a straight line calculated as;
m = y2-y1/(x2-x1)
This could give points like (5,0) and (0,3)
