Answer:
The midpoint of AB = (x,y)=(1,1)
Step-by-step explanation:
Given : A line AB
To find : Midpoint of AB.
Solution :
Consider the figure
Then , Points of A = 
= (-2,0)
Points of B = 
= (4,2)
Now to find mid point we will use midpoint formula :
Thus, The midpoint of AB = (x,y)=(1,1)
Answer:
$1200
Step-by-step explanation:
180 divided by 9 is 20, so they earned $20 per car washed. They want to wash 60 cars, and if they wash 60 cars they would earn $1200. (60 x 20)
B. 31°, 43°, 106°
since all angles of a triangle add up to 180°, you combine all of the equations to equal 180 and solve for X. the equation you would get it 3x+1+11x-4+5x-7=180. this simplifies to 19x-10=180. then you solve for x, and it is 10. then, you plug 10 into all of the equations separately to find the angles. therefore, the answer is B
Answer: The answer is C) y= 2/3x-3
Step-by-step explanation:
i figure it out
<span>i would just make this into an equation!!
t for the number of turkey sandwiches
s for the number of steak sandwiches
it's 4 dollars for every turkey sandwich and 6 for every steak sandwich, so:
4t + 6t = 4524
you can call this your "profit" equation. it just tells you how much money they made. however many sandwiches they sold at those rates gave them the outcome of 4524
then you need a second equation, to account for the number of sandwiches, and instead of worrying about profit you need to focus on the number of sandwiches sold (which is why they gave you the number 925)
t + s = 925
the number of turkey sandwiches plus the number of steak sandwiches adds up to a total of 925 sandwiches.
so you have two equations:
4t + 6s = 4524
t + s = 925
to figure out the number of turkey sandwiches sold, you want to solve for the variable t. this can be done a few ways with your two equations, but the easiest to follow will probably be substitution in this case.
first, isolate your variable t in one of the equations. it'll be easier with the second one.
t = 925 - s
then you plug that into your first equation:
</span>4(925 - s) + 6s = 4524
then solve it like normal.
4(925 - s) + 6s = 4524
3700 - 4s + 6s = 4524
3700 + 2s = 4524
2s = 824
s = 412
so now you know your s variable. plug that back into the following equation, and you have the number of turkey sandwiches sold:
t = 925 - s
t = 925 - (412)
t = 513
513 turkey sandwiches were sold
