The total cost for her jeans will be $84.
How to calculate the cost?From the information, Grace has a coupon for $2 off the regular price of each pair of jeans she buys and she buys 4 pairs of jeans with a regular price of $23 each.
The total cost for her jeans will be:
= (4 × $23) - (4 × $2)
= $92 - $8
= $84
Therefore, it should be noted that the total cost is $84.

f(x) = 3 x + 1 and g (x) = 2x - 3. find g (f(x))
Answer:
6x -- 1
Step-by-step explanation:
To Solve for g(f(x)), bear in mind
f(x) = 3x + 1
g(x) = 2x -- 3
g(f(x)) = 2x -- 3. (Calm down right?)
Let x = f(x).
if you recheck g(x) = 2x -- 3 so we got the (x) from it (do you get?)
g(f(x)) = 2(3x + 1) -- 3
g(f(x)) = 6x + 2 -- 3
g(f(x)) = 6x -- 1
#AllonGod
Answer:
Step-by-step explanation:
To find g(f(x)), first, understand that this means we are going to use the function of f(x) where the x would be in g(x).
1. First, identify the x in g(x) and replace it with the function of f(x)
g(x)=2x-3; so g(f(x))= 2(3x+1) -3
2. Simplify the equation by distributing the 2 and combining like terms.
2*3x=6x and 2*1=2, so we are left with 6x+2-3. After, just do 2-3 to end up with
g(f(x))=6x-1

a rectangular piece of metal is 10 in longer than it is wide. squares with sides 2 in long are cut from the four corners and the flaps are folded upward to form an open box. if the volume of the box is 671 in, what were the original dimensions of the piece of metal?
The length and width of the piece of metal are 28 and 18 inches respectively.
What is volume?
The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.
Dimension of the rectangle;
Width(w)
Length,L= 10 + w
volume of the box = length * width * height
Dimension of the box;
length of box, (x + 10) - 4 = x + 6
width of box,(x - 4)
height of box = 2
The volume of the box is 672 in³;
⇒V=lwh
⇒V=2 (x -4)( x + 6)
⇒672 in³ = 2x² + 4x - 48
⇒2x² + 4x - 720 = 0
⇒x^2 + 2x - 360 = 0
⇒(x +20)(x - 18) = 0
⇒x = 18
⇒x=-20 (value of the dimension will not be negative.
The width of an original piece of metal is;
Width,w=18 inches
length,l= 28 inches
Hence. the length and width of the piece of metal are 28 and 18 inches respectively.

Area of a triangle with a vertical height of 1/2 m and base of 1/4 m.
Answer:
1/16 squared meters
Step-by-step explanation:
The formula to find the area of a triangle is [tex]\frac{Base * Height}{2}[/tex]
We can form an equation if we substitute the values (base and height).
[tex]\frac{1/2*1/4}{2}[/tex]
1/2 * 1/4 = 1/8
and [tex]\frac{1/8}{2}[/tex] = 1/16
Therefore, the area of a triangle with a vertical height of 1/2 m and a base of 1/4 m is 1/16 meters squared.

a car travels 3.5 miles in 5 minutes. work out the average speed in miles per hour
The average speed of the car which travels 3.5 miles in 5 minutes is 42 miles per hour.
What is the average speed of the car?Speed is simply referred to as distance traveled per unit time. It is expressed mathematically as;
Speed = Distance ÷ time.
Given the data in the question;
Distance travelled = 3.5 milesTime elapsed = 5 minutesAverage speed = ?First, we convert unit of the elapsed time from minutes to hours.
Time = 5 min = ( 5/60 )hr = 5/60hr
Now, plug the given values into the speed formula and solve for speed.
Speed = 3.5 ÷ 5/60
Speed = 3.5 × 60/5
Speed = 210/5
Average speed = 42 mph

6x+26x-10=8(4x+10) write a word problem that this equation,or any of its equivalent forms,represents.
6x+26x-10=8(4x+10) quadratic equation has no solution.
First, Simplify the equation:
6x + 26x + (-10) = 8(4x + 10)
Now, reorder the terms:
(-10) + 6x + 26x = 8(4x + 10)
Combine the like terms:
6x + 26x = 32x
-10 + 32x = 8(4x + 10)
Then, reorder the terms:
-10 + 32x = 8(10 + 4x)
-10 + 32x = (10 × 8 + 4x × 8)
-10 + 32x = (80 + 32x)
Add '-32x' to each side of the equation.
-10 + 32x + -32x = 80 + 32x + -32x
Again, Combine like terms:
32x + -32x = 0
-10 + 0 = 80 + 32x + -32x
-10 = 80 + 32x + -32x
Repetitively, Combine like terms:
32x + -32x = 0
-10 = 80 + 0
-10 = 80
After Solving,
-10 = 80
Thus, there is no further variable to solve.
∴ This equation is invalid, the left and right sides are not equal, therefore there is no solution.

There are a total of 54 men.
Let's take x new men who joined the club, then according to the question (22-x) new women who joined the club.
[(98 × (5 ÷ 5 + 9)) + x ÷ [(98 × (9 ÷ 5 + 9)) + (22 - x)] ÷ [(98 × (9 ÷ 5 + 9)]= 9 ÷ 11
[(98 × (5 ÷ 14)) + x ÷ [(98 × (9 ÷ 14)) + (22 - x)] ÷ [(98 × (9 ÷ 5 + 9)]= 9 ÷ 11
[35 + x] ÷ [63 + (22 - x)] = 9 ÷ 11
11 × (35 + x) = 9 × (85 - x)
385 + 11x = 765 - 9x
11x + 9x = 765 - 385
20x = 380

Answer:
19
Step-by-step explanation:
Originally there are 98 members
Ratio of men to women = M:W = M/W = 5/9
The ratio of men to total number of members = M/(M + W) and this should be the same as 5/(5+9) = 5/14
Since 5/14 th of the total membership of 98 members is the number of men,
Actual number of men
= 98 x (5/14)
= 35
After 22 members join the club, the total club membership is 98 + 22 = 120
The new ration M/W = 9/11
Actual number of men members
= 120 x 9/(9+11)
= 120 x 9/20
= 6 x 9
= 54
Increase in the membership of men = 54 - 35 = 19

Last night, Luis read 75% more pages than Dayja, and Dayja read 75% more pages than Michael. If Dayja read 84 pages, how many pages did Luis, Dayja, and Michael read all together?
Answer:
252
Step-by-step explanation:
Altogether, Luis, Dayja, and Michael read 279 pages.
How do we get the total number of pages read by each person?We can get the total number of pages read by each person by building from the number of pages read by Dayja.
Dayja read 84 pages
Luis read 75% more pages than Dayja and this is equal to:
84 + 84 × 75/100
84 + 84 × 0.75
84 + 63
= 147 pages.
Dayja read 75% more pages than Michael.
Believing that Michael read x number of pages.
84 = 175 ÷ 100 × x
8400 = 175x
x = 8400/175
x = 48
So, Michael read 48 pages.

The value of y on the number line is 4.
How to find the side of a number line?A number line is a series of numbers placed on a straight line in order from least to greatest.
The number line is RT.
The point S is in between RT.
Therefore,
RT = RS + ST
Hence,
RT = 67
RS = 9y + 3
ST = 5y + 8
Therefore,
RT = RS + ST
67 = 9y + 3 + 5y + 8
67 = 9y + 5y + 11
67 = 14y + 11
subtract 11 from both sides of the equation
67 = 14y + 11
67 - 11 = 14y + 11 - 11

a heap of rubbish in the shape of a cube is being compacted into a smaller cube. given that the volume decreases at a rate of 3 cubic meters per minute, find the rate of change of an edge, in meters per minute, of the cube when the volume is exactly 64 cubic meters.
-1/16 meters per minute is the rate of change of an edge.
What is the rate of change?The rate at which one quantity changes in relation to another quantity is known as the rate of change function. Simply put, the rate of change is calculated by dividing the amount of change in one item by the corresponding amount of change in another.So, the Volume of the cube: V = r³
Where the edge of the cube is represented as r.Differentiate with respect to t (time) as follows:
[tex]\frac{d V}{d t}=3 r^2 \frac{d r}{d t}[/tex]dV/dt = -3 : Cubic meters per minute
Also, V = 64 ⇒ r = ∛64 = 4Now, substitute the values:
-3 = 3(4)² dr/dt-3 = 48 dr/dtdr/dt = -3/48 = -1/16Therefore, -1/16 meters per minute is the rate of change of an edge.
