Step 1: Define
16 < -2(x + 4)
Step 2: Solve for x
Distribute -2: 16 < -2x - 8Add 8 to both sides: 24 < -2xDivide -2 on both sides: -12 > xRewrite: x < -12Here we see that any number x smaller than -12 would work as a solution to the inequality.

Three times a number (n) is 36 less than five times the number (n). What is the number?
Answer:
18
Step-by-step explanation:
To find the number, write an algebraic equation with the given information. Let the variable n represent the unknown number.
Now, break it by parts - "three times a number" would be [tex]3n[/tex]. The "is" means that it equals something, giving us [tex]3n =[/tex]. "36 less than 5 times the number" would be subtracting 36 from whatever 5 times the number is: [tex]5n -36[/tex]. So, put it all together and it is [tex]3n = 5n-36[/tex].
Next, solve the equation for n. The answer will be the number.
[tex]3n = 5n-36\\0 = 2n - 36\\36 = 2n \\n = 18[/tex]
Thus, the number is 18.

Which list orders from least to greatest?
Answer:
D. -2 2/3, -2.5, 1.3, 1 1/2, 3
Step-by-step explanation:
The partial factorization of x2 – x – 12 is modeled with algebra tiles.
An algebra tile configuration. 4 tiles are in the Factor 1 spot: 1 is labeled + x, 3 are labeled +. 1 tile is in the Factor 2 spot and is labeled + x. 20 tiles are in the Product spot: 1 is labeled + x squared, 3 are labeled + x, the 4 tiles below + x squared are labeled negative x, and the 12 tiles below the + x tiles are labeled negative.
Which unit tiles are needed to complete the factorization?
Answer:
x² – x – 12 = (x – 4)(x + 3)
Step-by-step explanation:
Identify two numbers that add to -1 and multiply to -12, let's call them p and q.
So ax² + bx + c = (x + p)(x + q)
pq = c
p + q = b.
It is easier to find these numbers by finding factors of -12.
This can be done by splitting the number up until all the numbers are prime.
-12 → 6 × -2 or -6 × 2 → -(3 × 2 × 2)
There can only be two numbers so the only options we have are 6 and -2, -6 and 2, 3, and -4, or -3 and 4.
We can eliminate them by adding them up.
6 + -2 = 4 ≠ -1 so that can't be it.
-6 + 2 = -4 ≠ -1 so that can't be it either.
-3 + 4 = 1 ≠ -1
therefore p and q are 3 and -4 because 3 + -4 = -1.
so x² – x – 12 = (x – 4)(x + 3)
p = -4, and q = 3.
(x – 4)(x + 3) = x(x + 3) – 4(x + 3) = x² + 3x – 4x + 12 = x² – x – 12

We have the correct feet number (5) but the incorrect inches number (should be 3 inches and not 1/4 inches)
Step-by-step explanation:
Here, we want to make a conversion from feet to inches and feet
Mathematically, we know that;
1 feet = 12 inches
So, for 63 inches, we can have a clear ;
63/12 = 5 feet + 3 inches
Hence, the correct conversion of 63 feet should be;
5 feet and 3 inches

The Slope of a Line
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The line shown in the image is horizontal, i.e. all of its points have the same y-coordinate regardless of their x-coordinate.
Take two random points on the line like (0,-2) and (2,-2), the slope is:
[tex]\displaystyle m=\frac{-2+2}{2-0}=0[/tex]
The slope is zero

The selling price of an item is $650. It is marked down by 20%, but this sale price is still marked up from the cost of $400. Find the markup from cost to sale price.
Answer: The markup from cost to sale price = $120.
Step-by-step explanation:
Given: Selling price per item = $650
Marked down price = 20% of (Selling price)
= 0.20 x $650
= $ 130
New selling price = Old selling price - Marked down price
= $(650-130) = $520
Since new selling price is still greater than the cost of $400.
Mark up from cost to selling price = New selling price - Cost
= $(520-400)
=$120
Hence, the markup from cost to sale price = $120.
A gardener plants a row of eight trees chosen from three maples, two oaks, and four birches. In how many ways can he plant the row if:
trees of the same type have to be adjacent?
Answer:
18

each possibility needs to exclude one tree so:
mmoobbbb is when you exclude a maple
mmmobbbb is when you exclude an oak
mmmoobbb is when you exclude a birtch
then you can mix them up to get 6 ways per exclusion
6x3=18
so 18 is your answer!
Gabriella is three years younger than her sister, Amy. If
Gabriella is 5 years old, how old is Amy? Write an equation
to solve
Answer:
5+3 is Amy, so Amy is 8
Step-by-step explanation:
So, lets say amy is a
and gabriella is g
WE know that g=5, because gabriella is 5 years old
And, Gabriells is younger than Amy, so we need to add to get Amy's age
So, 5 ( Gabriella's age ) + 3=Amy
So, 5+3= Amy
So Amy is 8
Answer:
Amy is 8 years old.
Step-by-step explanation:
5 + 3 = 8
If Gabriella is three years younger then Amy then all you have to do is add 5 (Gabriella's age) plus 3 (how much older Amy is than Gabriella) and that is 8.
