Answer:
Keegan need to mow 11 times to his neighbors lawn to have enough money to buy the skateboards.
Step-by-step explanation:
Consider the provided information.
It is given that Keegan need $140 and Keegan saved $30. Keegan also charges $10 each time he completes the job writing.
Let x the number of times Keegan needs to mow his neighbors lawn to earn enough money.
Thus the required equation is;
Now solve the equation as shown below:
Hence, Keegan need to mow 11 times to his neighbors lawn to have enough money to buy the skateboards.
Answer:
Step-by-step explanation:
140-30=110
He charges 10$ every time he mowed someones lawn
So 110/10=11
He would have to mow his neighbors lawn 11 times.
2x + y = 14
a (3, 8)
b (-8, 3)
c (-3, 8)
d (8, 3)
Answer:
The answer is A.
Step-by-step explanation:
I used the elimination method to solve this system of equations.
The elimination method is where you add both of the equations, where one of the variables are equal in terms of number, but the signs are flipped. That's because you add the equations, crossing out one of the variables, leaving you with one variable to easily solve with.
It goes like this:
I multiplied the first equation (-3x+y=-1) by -1, to be able to cross out the y variable when I add.
So, after multiplying, the equation would be: 3x-y=1
Now, you add the two equations together.
3x-y=1
2x+y=14
+________
5x=15
Solving we get x=3.
That already gives you a as an answer, but let's continue.
Now we plug x=3 back into one of the equations to find what y is.
2(3)+y=14
6+y=14
y=8
So, the answer is A, (3, 8).
Checking: Just plug the numbers back in to see if they're right.
-3(3)+8= -1
-9+8=-1
-1=-1
Hope this helps!
19.98 = x + x(1.6)
19.98 = 1.6x + x
19.98 = 2.6x
x = 7.68
x(1.6) = 12.29
The cost is $7.68 and the markup is $12.29. (Approximate due to rounding)
Hope this helps!! :)
