You have just been paid for mowing nine lawns, and you earned $7 per lawn. If you were paid $9 per lawn, how many lawns would you have to mow to earn the same amount of money?
Answer:
if you got paid seven bucks per lawn, and you mowed nine lawns, you'd have $63 dollars
if you were to mow them for 9 dollars a lawn...
$63 = 9x
63/9 = 7
youd have to mow 7 lawns to get the same amount of money

The scale of a map says that 8 cm represents 5 km.
What distance on the map (in centimeters) represents an actual distance of 8 kilometers?
____ centimeters
What is the actual number of kilometers that is represented by 5 centimeters on the map?
____ kilometers
Please help
Answer:
1) 12.8cm
2) 3.125km
Step-by-step explanation:
1) 8cm = 5km
1km= 8/5
1km = 1.6cm
8km = 8*1.6
8km = 12.8cm
2) 8cm = 5km
1cm = 5/8
5cm = (5*5)/8
5cm= 25/8
5cm= 3.125km
Answer:
1) 12.8cm
2) 3.125km

What is the solution to the system of equations?
3x - 2y = 8
6x - 4y = 12
Use any algebraic method (substitution or elimination) to justify that the given system of equations has no solution.
What do you know about the two lines in this system of equations graphically?
Answer:
Answer:
[tex]\displaystyle Inconsistency\:[No\:Solution][/tex]
Step-by-step explanation:
We need to isolate one pair of variables so they are set to zero. Now, in this case, we need to split one of the equations in negative half, so we will select the second equation:
[tex]\displaystyle \left \{ {{3x - 2y = 8} \atop {6x - 4y = 12}} \right. \\ \\ \\ \left \{ {{3x - 2y = 8} \atop {-\frac{1}{2}[6x - 4y = 12]}} \right. \\ \\ \left \{ {{3x - 2y = 8} \atop {-3x + 2y = -6}} \right. \\ \\ \\ \boxed{0 \ne 2}[/tex]
The fact that we have a result like this proves that we cannot obtain a solution from this system, which means that on a graph, these equations are considered parallel [no intersection, so no solution].

1 Given That y varies directly as x. If x=5 when y=45 find x when y=270
Answer:
30
Step-by-step explanation:
y = kx
k= y/x
k= 45/5
k= 9
Therefore the value of x can be calculated as follows
k= y/x
x= y/k
x= 270/9
x= 30
if 3x + 28 = 46 what is the value of 2x + 6
Answer:
18
Step-by-step explanation:
3x + 28 = 46
Subtract 28 from each side
3x + 28 = 46
3x+28-28 = 46-28
3x=18
Divide each side by 3
3x/3 = 18/3
x = 6
Find 2x+6
2(6)+6
12+6
18
Hey there!
3x + 28 = 46
SUBTRACT 28 to BOTH SIDES
3x + 28 - 28 = 46 - 28
CANCEL out d 28 - 28 because it give you 0
KEEPs 46 - 28 because it help solve for the x-value.
NEW EQUATION: 3x = 46 - 28
SIMPLIFY IT!
3x = 18
DIVIDE 3 to BOTH SIDES
3x/3 = 18/3
CANCEL out: 3/3 because it give you 1
KEEP: 18/3 because it give you the x-value.
NEW EQUATION: x = 18/3
SIMPLIFY IT!
x = 6
Now that we have your x-value we can substitute it into the equation of: 2x + 6
SIMPLIFYING:
2x + 6
= 2(6) + 6
= 12 + 6
= 18
Thus, your answer is: 18
Good luck on your assignment & enjoy your day!

could someone please help me & explain?
Answer:
No.
Step-by-step explanation:
Let's substitute the given coordinate pair into each inequality:
[tex]y > 2x+6\\-4 > 2(-5)+6\\-4 > -10+6\\-4 > -4\rightarrow\text{Not true!}[/tex]
Since this coordinate pair does not satisfy the inequality (note the coordinate pair must satisfy BOTH inequalities), therefore (-5, -4) is not a solution to this system of inequalities.
Solve the following inequality algebraically (picture provided)
-2 < x/3 + 1 < 5
Subtract 1 from each side:
-2 - 1 < x/3 + 1 - 1 < 5 - 1
-3 < x/3 < 4
Multiply each side by 3:
-3 • 3 < x/3 • 3 < 4 • 3
-9 < x < 12

Amy, Jane, and Kayla bought tickets to a movie. Amy bought 2 adult tickets and 4 children tickets for $35. 50. Jane bought 3 adult tickets and 3 children tickets for $36. 0. How much will Kayla pay for 5 adult tickets and 4 children tickets?
Using a system of equations, it is found that Kayla will pay $54.25 for 5 adult tickets and 4 children tickets.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable x: Cost of an adult ticket.Variable y: Cost of a children ticket.Amy bought 2 adult tickets and 4 children tickets for $35.50, hence:
2x + 4y = 35.50
x + 2y = 17.75
x = 17.75 - 2y
Jane bought 3 adult tickets and 3 children tickets for $36.0, hence:
3x + 3y = 36
x + y = 12
From the first equation:
17.75 - 2y + y = 12
y = 5.75.
x = 17.75 - 2 x 5.75 = 6.25.
Hence the total paid for Kayla is given by:
T = 5 x 6.25 + 4 x 5.75 = $54.25.

Mrs. Rodger got a weekly raise of ₫145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
Let the 1st paycheck be x (integer).
Mrs. Rodger got a weekly raise of ₫ 145.
So after completing the 1st week she will get ₫ (x+145).
Similarly after completing the 2nd week she will get ₫ (x + 145) + ₫ 145.
