57-10.51=46.49
46.49-8.73=37.76
37.76-8.47=29.29
Therefore Daniel has $29.29 left.
Answer:
r=-2/3 or r= 6
Step-by-step explanation:
To solve this equation to find r, first subtract 5 from both sides.
3r² - 16r -7 -5= 5 -5
3r² - 16r -12= 0 (simplify)
(3r + 2)(r - 6)= 0 (factorise the equation)
3r+2=0 or r-6=0
3r= -2 or r= 6
r= -2/3
Plug the coordinate pairs into the equation. The first value is the x, and the second value is why. Solve the equation and if the answer on both sides is the same number, the coordinate pair satisfied the equation
Answer:
Yes
Step-by-step explanation:
To figure out if a triangle is a right triangle, you have to plug in the side lengths into the equation
+
= 
Your equation should look like 
Now you simplify. The equation should be: 26.01 + 46.24 = 72.25
Then add 26.01 and 46.24 to get 72.25 = 72.25
Since they are equal, the triangle is a right triangle.
