4 is addedthe sum is multiplied by 3the product has 2 subtractedWe can "undo" the last of these by adding 2 to both sides of the equation.
3(x +4) = 18
Undo the multiplication by 3 by dividing both sides by 3.
x +4 = 6
Undo the addition of 4 by adding -4.
x = 2 . . . . . the solution

Check
Put 2 in the equation where x is and see if it is true.
3(2 +4) -2 = 16
3(6) -2 = 16
18 -2 = 16 . . . . . true

The snake population on an island is declining at a rate of 2.7% per year. The population was 6000 in the year 2009.
What is the best prediction of the snake population in the year 2014?
Enter your answer, rounded to the nearest integer, in the box.
The snake population will be....?
Answer:
5190
Step-by-step explanation:
2.7% of 6000 is 162.
There is a 5 year span between 2009 and 2014.
So just subtract 162 from 6000 5 times, or multiply 162 by 5, then subtract that from 6000.
Hope It Helps!
what is the equation of the line that passes through point(-5,-3) and has a slope of -1
Answer:
y = -1x -2
Step-by-step explanation:
Just doing it in my head so im only like 90% sure edit: okay just checked my work and ya its y= -1x -2 :)
In this problem, we will be using the point-slope formula.
y - y₁ = m(x - x₁)
The point we are given, (-5, -3), represents (x₁, y₁) in the formula
and our slope which in this case is -1 represents our m.
Now let's plug all our information into the point-slope formula.
So we have y + 3 = -1(x + 5).
Remember that minus a negative means plus a positive
which is why I changed y - (-3) to y + 3 and the same for the x + 5.
So we have y + 3 = -1(x + 5).
Now distribute the -1 to get y + 3 = -x - 5
Now move the 3 to the right side by subtracting 3 to get y = -x - 8.
Now add x to both sides to get x + y = -8.
So the equation of this line in standard form is x + y = -8.

They arrive at the same answer because Jenna used the distributive property while Mia used the order of operations PEMDAS. In a lot of aspects of math, there are many approaches to reach the same answer.
Jenna's approach makes more sense, in my opinion, because when we multiply large numbers we're going to use the distributive property anyway. So why not just have it written down instead of done mentally in our head.
As a visual way to see why this works, check out the diagram below. We have a rectangle with height 5. The length of 34 is broken up into 30 and 4, so 34 = 30+4.
The blue portion has area of 5*30 = 150, while the red portion has area of 5*4 = 20. The two regions combine to 150+20 = 170.
So this diagram shows why Jenna's method is valid. Mia's method is valid as well, but again, we'll use some form of the distributive property to multiply 5 and 34. The only advantage that Mia has is that she uses one less written step compared to Jenna.

a music company sells music to download, they charge $7.00 for each album and $1.50 for each song. On monday the company sold a combined total of 170 albums and the songs that totaled $442.00 on monday what was the ratio of the number of albums sold to the number of songs sold?
A. 1:4
B. 7:1
C. 5:1
D. 1:14
Answer:
1:14
Step-by-step explanation:
The ratio of the number of albums sold to the number of songs sold is 1:4.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Charge for one Album = $7
Each song charges = $1.5
Total Albums and songs sold = 170
and, total worth of both = $442.00
The system of Equations can be
x + y = 170
and, 7x + 1.5y = 442
Then, 7x + 1.5(170 - x) = 442
7x + 255 - 1.5x = 442
5.5x = 187
x= 34
and, y= 170- 34 = 136
So, ratio = 34 / 136
= 1/4

At a campground, kayak rental company A charges a fixed amount of $10 plus $8 per hour for renting a one-person kayak. Company B charges a fixed amount of $6 plus $10 per hour for a one-person kayak.
Answer:
2hours
Step-by-step explanation:
Given data
Company A
charges a fixed amount of $10 plus $8 per hour
let the number of hours be x
and the total be y
y= 10+8x----------------1
Company B
charges a fixed amount of $6 plus $10 per hour for a one-person kayak.
let the number of hours be x
and the total be y
y= 6+10x----------------2
Equate 1 and 2 above
10+8x= 6+10x
collcet like terms
10-6= 10x-8x
4= 2x
x= 2hours
Hence after 2 hours the charges will be the same

a man walked for some distance at 8 km /h and for an equal distance at 5km/h. the total time he took was 3 whole number 1/4 hours. find the total distance he walked.
Answer:
the total distance walked is 20 km
Step-by-step explanation:
The computation of the total distance he walked is shown below:
Let us assume the total distance walked be d
Now the total time would be
Total time = (d ÷ 2) ÷ 8 + (d ÷ 2) ÷ 5 = 3.25
d ÷ 16 + d ÷ 10 = 3.25
(5d + 8d) ÷ 80=3.25
13d = 260
d = 20 km
Hence, the total distance walked is 20 km

Find the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1)
Answer:
The coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are [tex]\mathbf{(13,\frac{-9}{2})}[/tex]
Step-by-step explanation:
We need to find the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1)
The midpoint of line segment can be found using formula:
[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
We have [tex]x_1=14, y_1=-8, x_2=12, y_2=-1[/tex]
Putting values and finding midpoint
[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\Midpoint=(\frac{14+12}{2},\frac{-8-1}{2})\\Midpoint=(\frac{26}{2},\frac{-9}{2})\\Midpoint=(13,\frac{-9}{2})[/tex]
So, the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are [tex]\mathbf{(13,\frac{-9}{2})}[/tex]
