Question
The sum of a number and two more than twice the number is less than 50 (write in number form and solve)
Solution 1
N+2n+2 < 50
Combine like terms 3n+2< 50
Subtract 2 from both sides 3n<48
Divided both sides by 3
n<16

Question
A beach club made profits of $39,100 in May and $59,200 in August. What is the rate of change in the average monthly profit for this time period?
Solution 1
6,700 per month subtract 59200 from 39,100=20100
Divide by 3 because that’s the differences in month
20100 divide by 3 is 6700
Divide by 3 because that’s the differences in month
20100 divide by 3 is 6700
Question
a rectangular porch has dimentions of (x+12) and (x+5) feet. If thr aria of the porch floor is 120 square feet, what is its length and width?
Solution 1
We have (x+12)·(x+5) = 120; where x > 0;
Then, x^2 + 17x + 60 = 120;
x^2 + 17x - 60 = 0;
The solutions are x1 = +3 and x2 = -20;
Then, x = 3 is the correct solution.
Finally, x + 12 = 15 feet (length) and x + 5 = 8 feet (width).
Then, x^2 + 17x + 60 = 120;
x^2 + 17x - 60 = 0;
The solutions are x1 = +3 and x2 = -20;
Then, x = 3 is the correct solution.
Finally, x + 12 = 15 feet (length) and x + 5 = 8 feet (width).
Question
Y=2x-1
3y=6x-5
Please help
Solution 1
I gotchu this time buddy so substitute 2x-1 for the second equation: 3(2x-1)=6x-5
Distribute 3x :6x-3=6x-5
Subtract 6x from both sides
-3=-5 which is not true so the answer is no solution
Distribute 3x :6x-3=6x-5
Subtract 6x from both sides
-3=-5 which is not true so the answer is no solution

show work and i need really bad
Solution 1
We want to find the solution for the system of linear equations such that we know some points of the lines. We will see that the correct option is A: (-7, 4).
Systems of linear equations.
When we have a system of equations the solutions are the points where the graphs of the equations intercept.
Here we know that we have two lines:
- Line A passes through (-7, 4) and (3, - 10)
- Line B passes through (-7, 4) and (5, 11).
So we already can see that both lines pass through the point (7, -4), meaning that the lines do intercept at that point, so the solution of the system is that point (we know that we don't have more solutions because lines intercept only once).
So the correct option is A: (-7, 4)

Solution 2
Is it A since it passes thru both equations

Question
A cup has 4 pencils, 3 black pens, 1 blue pen, and 5 red pens. What is the probability of selecting a black or blue pen?
Solution 1
The probability of selecting a black or blue pen is 4 out of 13. You calculate this by adding the amount of pens together and comparing it to the total amount of pens and pencils in the cup.
Solution 2
4 out of 13 because in total there are 13 supplies in all and if you add 3 black pens PLUS 1 blue pen that will be 4.
Question
Solve the system of equations for 7x+2y=16 and -21x-6y=24
Solution 1
Simplifying
7x + 2y = 16
Solving
7x + 2y = 16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
7x + 2y + -2y = 16 + -2y
Combine like terms: 2y + -2y = 0
7x + 0 = 16 + -2y
7x = 16 + -2y
Divide each side by '7'.
x = 2.285714286 + -0.2857142857y
Simplifying
x = 2.285714286 + -0.2857142857y
7x + 2y = 16
Solving
7x + 2y = 16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
7x + 2y + -2y = 16 + -2y
Combine like terms: 2y + -2y = 0
7x + 0 = 16 + -2y
7x = 16 + -2y
Divide each side by '7'.
x = 2.285714286 + -0.2857142857y
Simplifying
x = 2.285714286 + -0.2857142857y
