It depends on the given information.
McKenzie's work is correct if the two short sides are given as 5 and 13.
Cara's work is correct is almost correct if 5 is one leg, and 13 is the hypotenuse. The exact answer is 12, but she wrote it as approximately equal. That's her only problem.
By the way, Ddssaa122: when posting questions, the power of a number is written as 5^2 and not 52. If you copy and paste, please make sure you add the caret sign to indicate a power, or else you will suffer by getting a wrong answer. 5^2=5*5, 52=4*13, so they are not the same.
So do
25x16=400
this shows how many raffle tickets were sold all together
Then do 400x$15 =$6000
So all together they raised $6000
Answer:
x = 18
Step-by-step explanation:
We need to find the value of x.
We know that the sum of angles of a triangle is equal to 180°. So, using this property,
2x+1+3x-1+90 = 180
2x+3x = 180-90
5x = 90
x = 18
So, the value of x is equal to 18.
Answer:
C
Step-by-step explanation:
its obvious.... i literally says which axis is X
Answer:
they are not parallel
Step-by-step explanation:
Given the equations -3x – 3y = 1 and -3x – 4y = 5
Get the slope of each line
REwrite in the form y = mx+c
For the line -3x-3y = 1
-3y = 3x + 1
y = 3x/-3 + 1/-3
y = -x - 1/3
Slope m = -1
For the line -3x - 4y = 5
-4y = 3x + 5
y = -3/4 x - 5/4
Slope of the line is -3/4
Hence since both lines have different slopes, they are not parallel
