Answer:
Step-by-step explanation:
Answer:
zero
Step-by-step explanation:
because when u equate both equation ,
-2x-5= -2x+7
or, -2x+2x=7+5
or, 0=12
which is invalid so it has no solution
5/8 9/x
Cross multiply
9x8=72
5×x=5x
Rewrite the equation
72 = 5x
Divide by 5
72÷5=14.4
So, x=14.4
If you have the calculator TI-84. press 2nd sin(56.3 divided by 80.2)=44.58728408 you must round the number because sometimes they ask to round the number. (don't forget to pre 2nd before you press sin)
