- He must sell each CD for R1,10 to make 40% profit
Step-by-step explanation:
R40×5%=2
R40-2=R38
40%×38=R15,2
15,2+40=55,2
55,2÷50=R1,10
i didnt do the radio sum...
Answer:A=X x=8
B=x X=9
C=x X=10
Step-by-step explanation:
Basically they want you to move the variables around so that it matches the standard form which is Ax+By=C.A,B,and C are just coefficients/constants.
so the original equation is
y=x-4
Minus x from both sides to move x to the left hand side.
-x+y=-4
so thats the final answer
7(x+y) because their both factors of 7
Its wrong for x = 2
y = (3/4) * 2^2 = 3 (NOT 4)
