I think the question is asking for the cost (C) when we already know that the sell price (S) is $24
So C+M=S
C+0.45C=24
1.45C=24
C=16.5516
And the answer is $16 and 55 cents
Step-by-step explanation:
okay I think you can solve this question now ☺️
False, it would not make a right triangle
Answer:
(-3,-20)
Step-by-step explanation:
4 +8x = y ...... equation (1)
6x - y = 2 ........equation(2)
from equation 2
6x - y = 2
6x -(4+8x) =2
6x - 4 + 8x = 2
+4 +4
6x - 8x = 6
-2x=6
divide by -2
x= -3
put x in equation (1) to solve for y
4 + 8x = y
4+8(-3)=y
4-24=y
-20=y
y= -20
solution = (-3,-20)
