Answer: 80 items
Step-by-step explanation:
The equation x=0.7x + 24 can be rewritten as 1x = 0.7x + 24 because the is a number on in front of any variable.
1x = 0.7x + 24 subtract 0.7 from both sides
-0.7 -0.7
0.3x = 24
x = 80
The answer is -6. Use the slope formula y2-y1/x2-x1
Answer:
0.05n + 0.25q = 1.60
q = 3n
0.05n + 0.25(3n) = 160
0.05n + 0.75n = 1.60...multiply by 100 to get rid of the decimals
5n + 75n = 160...answer D

Answer:
Ariel answer is wrong.
Step-by-step explanation:
Given that Ariel had done a Math problem for a triangle with sides
9,15 and 12. She concluded that these sides are not that of a right triangle.
To check whether Ariel is right:
Greater side = 15
Hence greatest angle will be opposite 15
Let us check pythagorean theorem
smaller sides are 9 and 12
Square and add them
9 square +12 square = 81+144 = 225 =15 square
We find that Pythagorus theorem is satisfied
Hence it is concluded that the triangle is right angled and Ariel was wrong
