Step-by-step explanation:
Expression can be broken down into a couple of parts.
A term (like 10s, or -2s)The variable (what the unknown value is being represented by, in this case, s)The coefficient (the number next to the variable, showing what to multiply the variable by - in this case, 10 and -2)When we have multiple terms with the same variable, we can perform operations on them assuming they have the same variable - for example, 5x + 6x = 11x, as 5+6=11.
We can apply the same logic here, however, note that adding a negative is the same as subtracting a positive. For example, 5 + -2 is the same as 5-2.
[tex]10 - 2 = 8[/tex]
Therefore, our final expression is [tex]8s[/tex].

Pedro is an airline attendant. Last week, he worked on flights on 4 small jets and 3 large jets, which could seat a total of 418 passengers. The week before, he was assigned to flights on 5 small jets and 3 large jets, which could seat a total of 464 passengers. How many seats were on each type of flight?
The flights on small jets each had _____seats, and the flights on large jets each had
______ seats.
Step-by-step explanation:
4s+3L=418 3L=418-4s
5s+3L=464
5s+418-4s=464
5s-4s=46
s=46
4×46+3L=418
184+3L=418
3L=234
L=78
Marilu invested $3,000 in a fund with an interest rate of 2.5% compounded semi-
annually. After 5 years what will the investment be worth?
A = P(1+)
$3,396.81
$9,633.10
$3,380.90
$3,518.18
$4,410.05
Answer:
$ 3,396.81
Step-by-step explanation:
The formula uses to calculate the amount of an investment after t years which is compounded is given as:
A = P(1 + r/n)^nt
Where:
A = Amount of Investment after t years
P = Principal = $3,000
r = Interest rate = 2.5 %
t = Number of years of Investment = 5 years
n = Compounding frequency = semi annually = 2
First, convert R percent to r a decimal
r = R/100
r = 2.5%/100
r = 0.025 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 3,000.00(1 + 0.0125/2)^(2×5)
A = $ 3,396.81
The total Investment from compound interest on an original principal of $3,000.00 at a rate of 2.5% per year compounded 2 times per year over 5 years is $ 3,396.81.
Solve for the missing side length
Need help please
Answer:
6
Step-by-step explanation:
Let the missing side be represented as x.
Applying the triangle proportionality theorem, we have:
[tex] \frac{15}{x} = \frac{14 - 4}{4} [/tex]
Solve for x
[tex] \frac{15}{x} = \frac{10}{4} [/tex]
Cross multiply
[tex] x(10) = 4(15) [/tex]
[tex] 10x = 60 [/tex]
Divide both sides by 10
x = 6

At the end of 2005, this price was `\$513.` At the end of 2015, it was `\$1060.` By what percentage did the price per ounce of gold increase?
Answer: The price per ounce of gold increases by 106.63%.
Step-by-step explanation:
Given: Price in 2005 = $ 513
Price in 2015 - $ 1060
Now , [tex]\text{Percentage increase in price}=\dfrac{\text{Change in price}}{\text{ Initial price}}\times100[/tex]
[tex]\Rightarrow\ \text{Percentage increase in price}=\dfrac{1060-513}{513}\times100\\\\=\dfrac{547}{513}\times100\\\\= 1.0663\times100\%=106.63\%[/tex]
hence, the price per ounce of gold increases by 106.63%.

Answer:
F. (-4, oo)
Step-by-step explanation:
Start from the left side.
The arrow on the left side shows that the graph continues increasing forever as x decreases. Beginning at the highest value of y you see on the left side at point (-6, 5), as x increases, moving right along the x-axis, the y-values decrease. When you get to x = -4, y is at its lowest value which is 1.
Starting just to the right of x = -4, the y-values begin to increase from the lowest y-value of 1. The arrowhead at the right side top shows that the curve continues increasing forever to infinity.
The values of x for which y increases are all values greater than -4 and all the way to positive infinity.
This function is increasing for x > -4.
Now we need to write x > -4 in interval notation.
In interval notation, use a curved parenthesis to mean a number that is not included. The interval starts at -4, so it starts as
(-4
Then you write a comma to separate from the value where the interval ends.
(-4,
The interval in x of increasing values goes to positive infinity, so now you write the infinity symbol, and you close the interval with a curved parenthesis. By convention, infinity always gets a curved parenthesis. Also, I'll use oo for infinity below.
(-4, oo)
Answer: F. (-4, oo)

Tony runs to keep fit. He wants to run a total of 20 km each week. Here are the
distances Tony ran last week.
6.25 km
4 km 750 m
872 km
Did Tony run 20 km last week? You must show how you got your answer.
Answer:
Tony run 19.5 km last week, so he must have run 0.5 km more, to complete 20km run last week.
Step-by-step explanation:
Distance Tony ran last week are
6.25 km
4 km 750 m
872 km (Note: This would be 8 [tex]\frac{1}{2}[/tex] km and not 872 km)
We will add all the distances to check if they sum up to 20km or not.
First we will convert 4 km 750 m into km
We know that 1000 m = 1 km
So, 1 m = 1/1000 km
750 m = 750/1000 = 0.75 km
Now 4km + 0.75 km = 4.75 km
So, 4 km 750 m = 4.75 km
and 8 [tex]\frac{1}{2}[/tex] km = 8.5 km
Now, finding Distance covered by Tony during last week = 6.25 km + 4.75 km + 8.5 km
= 19.5 km
So, Tony run 19.5 km last week, so he must have run 0.5 km more, to complete 20km run last week.
Using the graph below, find the value(s) of x for which f(x) = 5.
Answer:
We conclude that:
f(x) = 5 for x = -7, -6, -5, -4, -3, -2, -1, 0 and 2.
Step-by-step explanation:
From the diagram, it is clear that:
There are two parts of the graph:
LEFT GRAPHRIGHT GRAPHLEFT GRAPH
On the left side, the graph of the function indicates that the value of y remains 5 for the values x = -7, -6, -5, -4, -3, -2, -1, and 0.
In other words,
f(x) = 5, for x = -7, -6, -5, -4, -3, -2, -1, and 0.
RIGHT GRAPH
On the right side, the graph of the function indicates that the value of y is 5 at x = 2
In other words,
f(x) = 5, for x = 2.
Therefore, we conclude that:
f(x) = 5 for x = -7, -6, -5, -4, -3, -2, -1, 0 and 2.

0.1(0.5m+6)=2
Answer:
m=28
Step-by-step explanation:
0.1(0.5m+6)=2
Distribute
.05m +.6 =2
Subtract .6 from each side
.05m +.6-.6 = 2-.6
.05m = 1.4
Divide each side by .05
.05m/.05 = 1.4/.05
m = 28
