Answer:
(0,-8)
x=0
y=-8
Step-by-step explanation:
There are a couple of ways you can solve this I used what I think is called the elimination method
We first start by writing the equations in linear form (y=mx+b)
For the first one we have -12x-5y=40
we add 5y to both sides and subtract 40 to get
-12x-40=5y
divide by 5 to get
-12/5x-8=y
Then the second one we have
12x-11y=88
same deal here, add 11y and subtract 88 to get
12x-88=11y
divide by 11 and get
12/11x-8=y
We then set the two equations equal to each other and get
-12/5x-8=12/11x-8
We can add 8 to both sides and get
-12/5x=12/11x
Just by looking at it you can see that the only solution for x is 0
Plug in 0 to the first equation and get -12*0-5y=40
This means that -5y=40
Solve for y and get -8
Answer:
The total number of Green team members is 160.
Step-by-step explanation:
Given 90% of the total members present at the meeting which is 144.
Let the total number of members be x.
Hence we can say that, The total number of Green team members is 160.
Exterior angle is equal to sum of interior opposite angles hence,
req. angle = 80 + 62 = 142
Answer:
a.
b.
Step-by-step explanation:
a. According to the information given in the exercise, you know that the sale person's daily earnings is the sum of $115 plus a commission of his daily sales.
Therefore, if his daily sales are $1,565, then his comission is given by:
Knowing that his total earnings for that day are $240.20, you can write the following equation which can be used to find "x":
b. In order to find the commision percent (in decimal form) of the sale person's daily sales, you must solve for "x":
Multiplying it by 100, you get it in percent form:
