Answer:
9. x = 12
10. x = 31
Step-by-step explanation:
9. Corresponding angles are equal, so technically you can move that (7x - 20) to be diagonal with the (4x + 16). Along with the corresponding angle, diagonal angles are equal to each other. Therefore you can set (7x - 20) equal to (4x + 16) to find x.
7x - 20 = 4x + 16
Solve
3x - 20 = 16
3x = 36
x = 12
Therefore x is equal to 12
Check:
4(12) + 16
= 64
7(12) - 20
= 64
10. All angles in a triangle have to add up to 180 degrees. Therefore, you can write your equation like this:
x + 2x + 25 + 2x = 180
Combine like terms
5x + 25 = 180
Solve
5x = 155
x = 31
Therefore, x = 31.
Check:
31 + 2(31) + 25 + 2(31) = 180
31 + 62 + 25 + 62 = 180
180 = 180

Answers
Answer:
[tex]\mathbf{3x}[/tex] is the greatest common factor for the expression: [tex]3x^2 -9x[/tex]
Step-by-step explanation:
We need to find the greatest common factor for the following expression: [tex]3x^2 -9x[/tex]
Greatest common factor is the number, that is divisible by both numbers. In the given expression 3x is the greatest number that is divisible by all the terms
[tex]3x^2 -9x\\3x(x-3)[/tex]
So, [tex]\mathbf{3x}[/tex] is the greatest common factor for the expression: [tex]3x^2 -9x[/tex]

A student put $1,200 in a savings account paying simple interest of 4.5% per year. Find the total amount of the student's savings after 5 years. A: $700. B: $1470. C: $1000. D: $400
Answers
Answer:
(B) $1470
Step-by-step explanation:
Given that the principal initial amount, p=$1200
Rate of simple interest per year, r=4.5% = 0.045
Time, t=5 years
Interest after 5 years,
I=prt= 1200 x 0.045 x 5 = 270
Total amount = Principal initial amount + Interest
=1200+270=1470
So, the total amount of the student's savings after 5 years is $1470.
Hence, option (B) is correct.

Renee’s workout consists of biking and running. While biking she burns 10 calories per minute, and while running she burns 15 calories per minute. Renee wants to burn at least 900 calories each day.
Let x be the number of minutes she spends biking and let y be the number of minutes she spends running. Write an inequality that models this situation.
Answers
Answer:
10x + 15y ≥ 900
Step-by-step explanation:
She burns 10 calories per minute while biking and 15 calories per minute while running. For each exercise, the number of minutes multiplied by the number of calories burned per minute will give the total number of calories burned.
Calories burned while biking (10x) plus (+) calories burned while running (15y) is at least 900 (≥900).
The inequality that models this situation is therefore
10x+15y≥900
The required inequality that models the given situation is 10x + 15y ≥ 900.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
While biking, she burns 10 calories per minute, and 15 calories per minute while running. The total number of calories burned for each exercise is the number of minutes multiplied by the number of calories burned per minute.
Let x be the number of minutes she spends biking and let y be the number of minutes she spends running.
Calories burned while biking (10x) plus (+) calories burned while running (15y) is at least 900 (≥900).
As per the given situation, the required inequality would be as:
⇒ 10x + 15y ≥ 900
Thus, the required inequality that models the given situation is 10x + 15y ≥ 900.

Graham decided to play football this year instead of getting a part-time job. Last year he made about $1,100 during football season. He also spends about $9 on eating out after each game. His team plays a 10-game season. What is his opportunity cost of playing football?

The opportunity cost of playing football for Graham is $1,190.
What is the Opportunity cost?The opportunity cost of certain activity in microeconomic theory is the value or gain given up by engaging in that activity in comparison to engaging in an alternative activity. Simply put, if you do a bone activity, you forfeit the potential to choose another.
Given that Graham made $1,100 during football season. Also, Graham spends about $9 on eating out after each game and his team plays a total of 10 games in a season.
Therefore, the opportunity cost of playing football for Graham is,
Opportunity cost
= Amount that Graham would have made in a part-time job + Total cost of playing football season
= $1,100 + (Number of games × Amount spend in a single game)
= $1,100 + (10×$9)
= $1,100 + $90
= $1,190
Hence, the opportunity cost of playing football for Graham is $1,190.

VolumeThe units of density are mass per volume, so we can find the volume by dividing the mass by the density. The units basically tell you how to work the problem.

They are parallel, they will never intersect.
Step-by-step explanation:
Notice that they have exactly the same steepness, which means their slopes are identical. The only difference between the two lines is the y-intercept. If we shifted one line vertically toward the y-intercept of the other, they would become the same line.
This is the simplest form because you can’t combine x with 6.
