Answer:
B) n=-2
Step-by-step explanation:
First, distribute.
7(1+4n)-5=-38+8n
7+28n-5=-38+8n
Combine like terms.
2+28n=-38+8n
To make solving the equation easier, subtract 8n first, so there isn't a negative variable.
2+28n=-38+8n
-8n -8n
2+20n=-38
Subtract 2 on both sides.
2+20n=-38
-2 -2
20n=-40
Divide by 20 on both sides.
20n=-40
/20 /20
n=-2
Hope this helps!! Have a wonderful day :3
PEMDAS PLEASE HELPPPP!
Answer:
90xyz ÷xy
input the unknowns
x = 3, y = 5, z = 2
90*3*5*2 ÷ 3*5
2700 ÷ 15 = 180
Just to clarify, PEMDAS, is just an abreviation for:
P - Parentheses
E - Exponents
M - Multiply
D - Divide
A - Add
S - Subtract
These are called order of operations following which part of you're equation you solve first. Hope this helped :)
2. Evaluate the expression for q = 2 6
Answer:
12
Step-by-step explanation:
This may not be intirely correct because you said q = 2 6. I think that means 2 times 6.
Anyways
2 x 6 = 12
⇒ q = 12
What is the additive inverse of the number 3?
3
0
-3
6
Answer:
-3
Step-by-step explanation:
The additive inverse of a number means that the sum of the number, and it's additive inverse will always be zero. The additive inverse is found by simply negating a number or making it opposite.
Therefore, 3 + x = 0, 3 - 3 + x = 0 - 3, x = -3. (x represents it's additive inverse)
Just keep in mind that finding it's additive inverse is usually the best way to do it.
Here are some ways to negate a number:
Zero subtracted by the number. (0 - n) not (n - 0).Multiplying or dividing the number by negative one. (n / -1 or n × -1)Subtracting a number by the second multiple of itself. (n - 2n) not (2n - n).________________________________
(2x + 3) (2 - 8) = 0,
Step-by-step explanation:
(2x + 3) (2-8)=0
2x( 2-8)+3(2-8)= 0
4x - 16x + 6 - 24 = 0
-12x - 18= 0
-12x= 18
x= -18/12
x = - 3/2
Jordan has a garden that is enclosed by a rectangular fence. The perimeter of the garden is 84 feet. The length of one side of fencing is 8 yards. What is the area of Jordan's garden?
Answer:
504 ft
Step-by-step explanation:
Perimeter = 2(width) + 2(length)
Convert yards to feet
1yard=3feet
8yards=?
8*3/1 = 24feet
84 = 2(w) + 2(24)
84 = 2w + 42
84 - 42 = 2w
42 = 2w
w = 21
Area = 1 * w
= 21 * 24
= 504 ft

Alyssa's company makes a profit of $175,000.
The company then experiences a loss of
$25,000 each month for the next five months.
Which expression represents the net profit
after five months?
Conchita starts a savings account. She deposits $100 from her parents. After that, she
deposits $10 each month. Write an algebraic expression to give the amount of money she
has saved after m months.
Answer:
$100 + $10m
Step-by-step explanation:
A = Account Balance = 100
After M months
A = $100 + $10m
Help please! I just don’t understand
===================================================
Work Shown:
(angle HID) + (angle DIJ) = angle HIJ
(100) + (8x+11) = 21x+7
100+8x+11 = 21x+7
8x+111 = 21x+7
111-7 = 21x-8x
104 = 13x
13x = 104
x = 104/13
x = 8
Use this x value to find angle HIJ
angle HIJ = 21x+7
angle HIJ = 21*8+7
angle HIJ = 175 degrees
---------------------------
Extra info:
You can also use that x value to find angle DIJ
angle DIJ = 8x+11
angle DIJ = 8*8+11
angle DIJ = 75
Then add this to angle HID to get
angle HID + angle DIJ = 100+75 = 175
This matches with angle HIJ = 175
So this confirms angle HID + angle DIJ = angle HIJ which helps confirm our answers.

What compound inequality describes this graph
Answer:
0≥x<4
Step-by-step explanation:
first, let's look at this number line.
there is a closed circle at 0 and an open circle at 4. this means that 0 is included (≤ or ≥) and that 4 is not included (< or >).
these are the endpoints, meaning that in this compound inequality, the numbers next to the symbols are 0 and 4.
x is in the middle of this compound inequality.
0 x 4
now, we have to figure out the symbols in between. i wrote out our choices above for each number. the highlighted portion is greater than or equal to 0 and less than 4, so we can write this compound inequality as the following:
0≥x<4
x is greater than or equal to 0, but less than 4
The dot plots represent the number of students who enrolled each year for the AP psychology course at two schools. The data represents the last 24 years. Which statement is true based on the mean number of students enrolled in the course?
D
The mean for school 1 is 466/24=19.42 (rounded)
The mean for school 2 is 537/24=22.375
It doesn't ask for the mean absolute deviation, otherwise it would be the reverse of d (which is c).

Drag the tiles to the correct boxes to complete the pairs. Item Original Price Discount Shirt $15 20% Pair of Pants $28 15% Pair of Shoes $35 40% Tie $12 15% Match the items with their prices after the discount. 3 ties 2 shirts 1 pair of shoes 1 pair of pants $24.00 arrowRight $21.00 arrowRight $30.60 arrowRight $23.80 arrowRight
Answer:
Shirts : $24
Pants : $23.80
Shoes : $21
Ties : $30.60
Step-by-step explanation:
For the shirt : Price = $15 Discount = 20% 2 shirts are bought
Price after the discount = (100% - 20%) x (2 x $15) = $24
For the pair of pants : Price = $28 ; Discount = 15% ; 1 pair of pants is bought
Price after the discount = (100% - 15%) x $28 = $23.80
For the shoes : Price = $35 Discount = 40% 1 pair of shoes are bought
Price after the discount = (100% - 40%) x $35 = $21
For the tie: Price = $12 Discount = 15% 3 ties are bought
Price after the discount = (100% - 15%) x ( 3 x $12) = $30.60
Answer:
Shirts : $24
Pants : $23.80
Shoes : $21
Ties : $30.60
Step-by-step explanation:
For the shirt : Price = $15 Discount = 20% 2 shirts are bought
Price after the discount = (100% - 20%) x (2 x $15) = $24
For the pair of pants : Price = $28 ; Discount = 15% ; 1 pair of pants is bought
Price after the discount = (100% - 15%) x $28 = $23.80
For the shoes : Price = $35 Discount = 40% 1 pair of shoes are bought
Price after the discount = (100% - 40%) x $35 = $21
For the tie: Price = $12 Discount = 15% 3 ties are bought
Price after the discount = (100% - 15%) x ( 3 x $12) = $30.60

you should get 4Solve the inequality: -6n - 12 >= 3(-n + 12)
Answer:
-16 > n or n < -16
Step-by-step explanation:
First, we can write the inequality and distribute.
-6n-12 > 3(-n+12)
-6n-12 > -3n+36
Get rid of a variable first (it makes solving a lot easier). We can add 6n to both sides.
-6n-12 > -3n+36
+6n +6n
-12 > 3n+36
Now, we can subtract 36 on both sides.
-12 > 3n+36
-36 -36
-48 > 3n
Divide by 3 on both sides.
-48 > 3n
/3 /3
-16 > n or (if it's easier) n < -16
