Adrian has 12 pounds of coffee. He wants to repackage the coffee into bags of 2/3 pounds. How many bags of coffee can he make?
Answer:
18 bags of coffee
Step-by-step explanation:
12 divided into 2/3 is the same as 12 multiplied by 3/2
12 x (3/2) = 18
18 bags x( 2/3) pounds of coffee each = 12 pounds of coffee

Step-by-step explanation:
17x-4=12+15x
add 4 on both sides to get
17x=16+15x
now subtract 15x on both sides to get
2x=16

(-4/3)x -6 =26
solve for x
Answer:x =24
Step-by-step explanation: If we reverse that we will get x= 32x3/4 which is 24
Answer:
x = -24
Step-by-step explanation:
(-4/3)x -6 =26
Add 6 to both sides:
(-4/3)x = 32
(-4/3) = -1.33333333
divide both sides by -1.33333333
x = -24
Substitute:
(-4/3)(-24) -6 =26
32 - 6 = 26
26 = 26
x = -24
A quadratic equation is shown below.
6x^2 = 10x - 1
What are the solutions to the quadratic equation?
Answer:
Two roots are:
[tex]x = \frac{ 5 + \sqrt{19}}{6}\\x = \frac{ 5 - \sqrt{19}}{6}[/tex]
Step-by-step explanation:
[tex]6x^2 = 10x - 1\\6x^2 - 10x + 1 = 0\\\\x = \frac{ 10 + \sqrt{10^2-4*6}}{2*6}\\x = \frac{ 10 + \sqrt{76}}{12}\\x = \frac{ 5 + \sqrt{19}}{6}\\x = \frac{ 5 - \sqrt{19}}{6}[/tex]
Stan has $95. He wants to buy as many movies as he can. All movies are originally
$12.00 and are on sale for 10% off. Tax is 5%
Answer:
Step-by-step explanation:
Each movie is $12.00. 10% off of 12% is 12-1.2 = 10.8
The final amount spent is 5%, that means we can multiply the end amount spend by 1.05
The maximum Stan can spend is $95
[tex](10.8m)*1.05\leq 95\\(10.8m)\leq 90.4762\\m \leq \frac{90.4762}{10.8}\\m\leq 8.3774[/tex]
Now, you can't buy 0.3 of a movie, so the most Stan can buy is 8 movies

x - 2y < 2
graph the inequality
Answer:
y > 1/2x - 1
First, draw the dashed line y = 1/2x - 1 (slope intercept ; y = mx + b).
Start at -1 on the y-axis, and continue going 2 units to the right, and 1 unit up for the right side of the graph.
Then starting at -1 on the y-axis, continue going 2 units to the left, and 1 unit down for the left side of the graph.
Explanation:
Convert standard form (Ax + By = C) by isolating y from the rest of the equation.
Ax + By = C → y = -Ax/B + C/B → y = mx + b.
Given a standard form equation in inequality form,
x - 2y < 2.
Set it to slope-intercept as an inequality to find the slope and y-intercept.
When negating (making opposite) a variable, you flip the inequality.
x - 2y < 2 → x - 2y - x < 2 - x → -2y < -x + 2 → 2y > x - 2 → y > 1/2x - 1.

Use the Remainder Theorem to determine whether or not x + 3 is a divisor of p (x) = 2x^3 + 4x^2 - 2x + 12
PLEASE SHOW WORK.
Step-by-step explanation:
This is answer. I'm sri lankan. But our a/l exam have this mathematics questions
The remainder when the polynomial p(x) = 2x³ + 4x² - 2x + 12 is divided by x + 3 is -6.
A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.
The remainder theorem states that for a polynomial, f(x) divided by a linear polynomial , x - a, the remainder is equal to f(a).
Given the polynomial; p(x) = 2x³ + 4x² - 2x + 12, since it is divided by x + 3, hence:
x + 3 = 0
x = -3
p(-3) = 2(-3)³ + 4(-3)² - 2(-3) + 12 = -6
Hence the remainder when the polynomial p(x) = 2x³ + 4x² - 2x + 12 is divided by x + 3 is -6.

Lakita wants to go to trade school and study electronics for a two-year program. Her tuition and books will cost about $5,500 per year. She will also spend about $100 a month commuting from her parents’ house to school. How much will her education cost her in total?
Answer:
$13,400
Step-by-step explanation:
Given the following data;
Tuition and book per year = $5,500
Transportation per month = $100
In 2 years;
Total tuition and book = $5,500 * 2 = $11,000
Total tuition and book cost = $11,000
Transportation;
There are 12 months in a year, in 2 years = 12 * 2 = 24 months.
Thus, total on transportation = $100 * 24 = $2,400
Total transportation cost = $2,400
[tex] Overall \; cost = Total \; tuition \; and \; book \; cost + Total \; transportation \; cost[/tex]
Substituting into the above equation, we have;
Overall cost = $11,000 + $2,400
Overall cost = $13,400.
Hence, Lakita's education will cost her $13,400 in total.

Answer:
19) x = number of people; y = cost
20) (people, cost) = (15, 120) and (25, 200)
21) the rate of change is $8 per person
22) y = 8x
23) $320
Step-by-step explanation:
19) The problem statement tells you x is the number of people and y is the cost.
__
20) Writing the pairs (people, cost), we have ...
(15, 120) and (25, 200)
__
21) The rate of change can be found from the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (200 -120)/(25 -15) = 80/10 = 8
The rate of change is $8 per person.
__
22) In point-slope form, the rule is ...
y -y1 = m(x -x1)
y -120 = 8(x -15)
y = 8x -120 +120
y = 8x
__
23) For x=40, y = 8(40) = 320
A party for 40 people will cost $320.
