Answer:
6: x = 3 and y = 5
7: x = 8 and y = 7
Step-by-step explanation:
In parallelograms opposite sides are congruent
For #6
x + 5 = 2x + 2
step 1 subtract x from each side
2x - x = x
x - x cancels out
now we have 5 = x + 2
step 2 subtract 2 from each side
5 - 2 = 3
2 - 2 cancels out
we're left with x = 3
y + 10 = 2y + 5
step 1 subtract 5 from each side
10 - 5 = 5
5 - 5 cancels out
now we have y + 5 = 2y
step 2 subtract y from each side
y - y cancels out
2y - y = y
we're left with y = 5
For #7
3x - 2 = 2x + 6
step 1 add 2 to each side
-2 + 2 cancels out
6 + 2 = 8
now we have 3x = 2x + 8
step 2 subtract 2x from each side
3x - 2x = x
2x - 2x cancels out
we're left with x = 8
6y - 8 = 4y + 6
step 1 add 8 to each side
-8 + 8 cancels out
6 + 8 = 14
now we have 6y = 4y + 14
step 2 subtract 4y from each side
6y - 4y = 2y
4y - 4y cancels out
now we have 14 = 2y
step 3 divide each side by 2
2y / 2 = y
14 / 2 = 7
we're left with y = 7

Answers

Answer:
C. $1.50
Step-by-step explanation:
The graph is a straight line through the origin, so the revenue is proportional to the number of tickets. The ratio of revenue to tickets will tell you the money raised for each ticket sold. Pick any point on the graph and divide the revenue value by the number of tickets.
The division can be easy if the number of tickets is 10. We see that the revenue for 10 tickets is $15, so the amount raised for each ticket is ...
$15/10 = $1.50 . . . . raised per ticket sold

Explain in words how you would graph the following inequality on a number line. 3x < 12 HELPPPPPPPPPPP PLSSSSSS
Answers
Answer:
x<4
Step-by-step explanation:
3x < 12
Divide with 3 on each side
x< 4
In words x has all the real numbers that are less than 4 or x belongs to any number from -ve infinity to 4.
The graph of the inequality 3x < 12 on a number line would consist of an open circle at 4, followed by a shaded region to the left of 4 and extending indefinitely in that direction.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
To graph the inequality 3x < 12 on a number line, we can follow these steps:
- Start by isolating x by dividing both sides of the inequality by 3, which gives us x < 4.
- Draw a number line and mark a point at 4, which is the boundary between the values of x that satisfy the inequality and those that don't.
- Since the inequality is strict (i.e., "less than" and not "less than or equal to"), we need to indicate that the point x = 4 is not included in the solution set.
We can do this by making an open circle (or "unfilled dot") at 4 on the number line.
- Shade the portion of the number line to the left of the point x = 4, since these are the values of x that satisfy the inequality 3x < 12.
We can use an arrow pointing to the left to indicate that the shaded region extends indefinitely in that direction.
Thus,
The graph of the inequality 3x < 12 on a number line would consist of an open circle at 4, followed by a shaded region to the left of 4 and extending indefinitely in that direction.

Suppose Hailey has taken four exams and made 86, 94, 76, and 81. If each exam counts equally, what does Hailey need to make on her fifth test to have an overall average of 85?
Answers
Answer:
She has to get a score of 88 on that test
Step-by-step explanation:
Take the average of the other grades, and that gives you 84.25. So she has to think about what rating she gives it is 85, and the rating is 88.
Hailey needs to score an 88 on the last exam in order to get an average of 85.
The overall average is the mean and the mean is calculated by adding up all the scores and then dividing by the number of exams.
There are 5 exams but only 4 scores. The 5th score will be denoted, "x" and the average we are looking for is 85.
The fifth score should therefore be:
Overall score = Sum of 5 exams / 5
85 = (86 + 94 + 76 + 81 + x) / 5
85 x 5 = 337 + x
425 = 337 + x
x = 425 - 337
= 88
In conclusion, Hailey needs a score of 88 on the fifth exam.
