Answer:
x= 20
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
3x-1(3)-8= 1(4)+4x+5
Step 2- Multiply
3x-3-8= 4+4x+5
Step 3- Add.
3x-3-8= 4x+9
Step 4- Subtract 3x to both sides to move the variable to one side.
3x-11= 4x+9
-3x -3x
Step 5- Subtract 9 to both sides.
-11= 1x+9
-9 -9
-20= x
Exchange the signs.
20= x
Answer:
x = -20
Step-by-step explanation:
3(x - 1) - 8 = 4(1+x) + 5
3x - 3 -8 = 4 + 4x + 5
3x - 11 = 9 + 4x
-x = 20
x = -20

Answer:
x = 76
Step-by-step explanation:
∠ DIJ and ∠ HIJ are adjacent and supplementary, thus
∠ DIJ = 180° - 107° = 73°
The sum of the 3 angles in Δ DIJ = 180° thus
∠ DJI = 180° - (73 + 31)° = 180° 104° = 76°
∠ DJI and x are vertical angles and congruent , thus
x = 76

It takes 2 finish carpenters 8 days to do the work. Each finsh carpenter ears $37.50 per hour and works 7 hours per day. How much will it cost to hire the finish carpenters?
Answer:
Total cost= $4,200
Step-by-step explanation:
Giving the following information:
It takes 2 finish carpenters 8 days to do the work.
Each finish carpenter ears $37.50 per hour and works 7 hours per day.
To determine the total cost, first, we need to structure the total cost formula:
Total cost= 2*(37.5x)
x= total number of hours
Now, for 8 days:
Total hours= 8*7= 56
Total cost= 2*(37.5*56)
Total cost= $4,200
For the pair of functions, find (f o g)(x) and (gof)(x).

What is the volume of this rectangular prism?
Answer: V≈5.21 cm³
Step-by-step explanation:
To find the volume of a rectangular prism, you multiply the length, width and height.
[tex]V=wlh[/tex]
Since we were given the length, width and height, we can directly multiply them together.
[tex]V=\frac{5}{2} *\frac{5}{3} *\frac{5}{4}[/tex] [multiply]
[tex]V=\frac{125}{24} =5.21 cm^3[/tex]
Now, we know that the volume is approximately 5.21 cm³ or 125/24 cm³.

Factor the following polynomial completely. x²n - y²n
Answer:
(n)*(x+y)(x-y)
Step-by-step explanation:
First of all, you take the n out, and then you use the formula of x²- y² and it will equal to (x+y)(x-y).
Answer:
n(x+y)(x−y)
Step-by-step explanation:
1. To factor this equation, first, you can see that both the x^2 and the y^2 have an n next to them. So, you can take out the n. You get this: n(x^2-y^2)
2. After you take the n out, you can also factor the (x^2-y^2) since they are both squared (to the second power). To do this, you simply split the two apart and make sure to include the negative. You get this, the final answer:
n(x+y)(x-y)
3. You can check it by multiplying out the answer, and once multiplied out, you get the original expression of x^2n-y^2n.

Is 27.14 rational or irrational
Answer:
Rational
Step-by-step explanation:
A rational number is any number that repeats and/or isn't infinite. An irrational number is a number that is infinite and never repeats. (Like Pi. 3.1415926535... etc.) 27.14 isn't infinite so therefore it's rational.

x = 10
PT = 34
Step-by-step explanation:
PT = 4x - 6 and TQ = 3x + 4
if PT = TQ
4x - 6 = 3x + 4
4x - 3x = 4 + 6
x = 10
PT = 4x - 6
PT = 4 (10) - 6
=40 - 6
PT = 34
The value of PT = 34

Answer:
3ny
Step-by-step explanation:
For this problem, the price of a widget is represented by 'n' amount of dollars. Additionally, the store was stocked with 4y widgets.
To find the total cost of the widgets sold, we will use the information that at the end of the day, the store only had y widgets remaining.
From here we can say the following to represent the total cost of the widgets sold:
cost = n * (4y - y)
cost = n * (3y)
cost = n3y
You can rewrite this cost to be 3ny as in the answer choice.
Cheers.
Karina and Perry are cleaning up litter in the park for community service hours. Karina and Perry both claim they have covered the greatest area. Who is correct? Justify your answer using mathematical reasoning.
Answer:
Perry is correct, she covered the greatest area = 18 square units.
Step-by-step explanation:
Looking at the attached diagram, the shapes are rectangular and they are on grid or graph
Note that on a graph:
1 square box = 1 unit
Area of rectangle = Length × Width
For Karina
The Width = 3 units
The length = 4 units
The area which Karina covered = 3 units × 5 units
= 15 square units
For Perry
The Width = 9 units
The length = 2 units
The area perry covered = 9 units × 2 units
= 18 square units
Therefore, Perry is correct, she covered the greatest area = 18 square units.

At an ice cream store, a family ordered 1 banana split and 2 hot fudge sundaes, paying a total of $11 for their order. The next customer ordered 4 banana splits and 3 hot fudge sundaes and paid $29. How much does each item cost?
Answer:
$5 and $3
Step-by-step explanation:
Cost of banana split = b
Cost of hot fudge sundae = s
b + 2s = 114b + 3s = 29From the first equation we get:
b = 11 - 2sReplacing in the second equation:
4(11 - 2s) + 3s = 2944 - 8s + 3s = 2944 - 29 = 5s15 = 5ss = 15/5s = 3Then
b = 11 - 2*3 = 11 - 6 = 5So banana split costs $5 and hot fudge sundae costs $3
