Answer:
6x + 11x - 10
Step-by-step explanation:
So in order to solve this expression, we have to distribute the numbers in each set of parenthasis
Step 1 : break down each mini-espression you're solving
(2x+5)(3x-2)
each term is multiplied by both terms in the other set of parenthasis.
(2x · 3x) + (2x · -2) + (5 · 3x) + (5 · -2)
Step 2 : Solve each idividual piece
(2x · 3x) = 6x²
(2x · -2) = -4x
(5 · 3x) = 15x
(5 · -2) = -10
Step 3 : Put it all together amd simplify
6x² - 4x + 15x - 10
6x² + 11x - 10

2. The number of atoms of a particular chemical element is modelled by
the following function: y=600 x 3-* where x is the number of hours.
a) How many atoms of the element were there at the start?
b) Draw a graph for 0
c) At what time were there 150 atoms?
Answers
9514 1404 393
Answer:
a) 600
b) see below
c) 1.26 hours
Step-by-step explanation:
a) The value of y when x=0 is the coefficient of the exponential term:
y = 600·3^(-0) = 600·1 = 600
There were 600 atoms to start.
__
b) see attached for a graph
__
c) The graph shows 150 atoms at t = 1.26, about 1.26 hours after the start of time counting.
If you want to find that value algebraically, substitute for y and solve for x. Logarithms are involved.
150 = 600·3^(-x)
150/600 = 3^(-x)
log(1/4) = -x·log(3)
x = -log(1/4)/log(3) = log(4)/log(3) ≈ 1.2618595
After about 1.26 hours, there were 150 atoms.
Max and Jay Are running a lemonade stand they spent $12 on all the material and charge $1.50 for each cup of lemonade write an equation that will allow you to calculate the profit (P) if you are told the number of cups (c) that are sold.
Answers
Answer:
P = $1.50c - $12
Step-by-step explanation:
profit = total revenue - total cost
total revenue = price per cup x total cup sold = $1.5 x c = 1.5c
Cost = $12

Angus Cut His Neighbors' Lawns For The Summer. By The End, He Had $325 In His Lawn-cutting Bank Account And He Paid A Total $75 For Gas. He Earned $10 For Ever Lawn He Mowed. How Many Lawns Did He Buy? A. N = 400 x 10 b n 250 x 10 c. N = 400 / 10 d. N = 250 / 10
Answers
Answer:
C. N = 400 / 10
Step-by-step explanation:
Lawn-cutting Bank Account = $325
Amount paid for gas = $75
Total amount earned = Lawn-cutting Bank Account + Amount paid for gas
= $325 + $75
= $400
Amount earned per every lawn he mowed = $10
How Many Lawns Did He mow?
Let N = number of lawns he mowed
N = Total amount earned / Amount earned per every lawn he mowed
N = 400 / 10
N = 40 lawns

How long will it take Eniola to save $5,000 if she started with $500 and found a rate of 6.2%? Round to the nearest whole number.
Answers
Answer:
the time period is 38.28 years
Step-by-step explanation:
The computation of the time period is shown below:
Given that
RATE = 6.2%
PV = $500
PMT = $0
FV = $5,000
The formula is shown below:
= NPER(RATE;PMT;-PV;FV;TYPE)
After applying the above formula, the time period is 38.28 years
Hence, in order to save $5,000 it would take 38.28 years

If the area of a rectangle in terms of x is x2 + 15x + 26 / 6x2 and its width is x2 - 3x - 10 / 30x3 Find the length of the rectangle.
Answers
Answer:
The length of the rectangle is;
5x(x+13)/(x-5)
Step-by-step explanation:
Mathematically, we know that the area of a rectangle is the product of the length and width of the triangle
To find the length of the rectangle, we will have to divide the area by the width
we have this as;
(x^2 + 15x + 26)/6x^2 divided by (x^2-3x-10)/30x^3
thus, we have ;
(x^2 + 15x + 26)/6x^2 * 30x^3/(x^2-3x-10)
= (x^2+15x+ 26)/(x^2-3x-10) * 5x
But;
(x^2 + 15x + 26) = (x+ 2)(x+ 13)
(x^2-3x-10) = (x+2)(x-5)
Substituting the linear products in place of the trinomials, we have;
(x+2)(x+13)/(x+2)(x-5) * 5x
= 5x(x+13)/(x-5)

List three values for x that would make 5x < -20 true.
Answers
Answer:
1. -5
2. -6
3. -10
Step-by-step explanation:
There are x = - 6, -7, and - 8 three values for variable x that would make 5x < -20 true.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
We have been given that the inequality is below as
⇒ 5x < -20 ...(i)
⇒ 5x / 5 < -20 / 5
⇒ x < - 4
Thus, all the negative values which are less than -4 for x would make it true.
For example, we take x = -8
Substitute the value of x = -8 in the inequality (i),
⇒ 5(-8) < -20
⇒ - 40 < -20
This is true.
Similarly x = - 6, and - 7 also for x would make it true.
Hence, there are x = - 6, -7, and - 8 three values for variable x that would make 5x < -20 true.

A pair of sunglasses is on sale for $17. Last week, the sunglasses were marked at a regular price of $20. What was the percent of change?
Answers
Answer:
15%
Step-by-step explanation:
17/20 the 17 is the part, and the 20 is the whole
17/20 = x/100
cross multiply
17*100= 1,700 divide by 20
=85
The price reduced to 85% the original price, but to find out how much it changed, you have to subtract the part from the whole meaning
100% - 85% = 15%
