Simplify 10^4 to 10000
8.5x10000-3.0x10^3
Simplify 8.5x*10000 to 85000x
85000x-3.0*10^3
Simplify 3.0x10^3 to 3*10^3
Answer 85000x-3*10^3
Cost/(number of cassettes) = $14.50/2 = x/15
Multiply by 15 to solve
15*($14.50/2) = x = $108.75
15 cassettes will cost $108.75.
Answer is 24.
firsty remember OF= MULTIPLY
NOW we can calculate this easily
here the equation is given
2/5×60. u can solve this in given ways below….…..
1……….
u can simply divided 60 by 5. which is equal to 12. and now the equation remain 2×12 . & it's equal to 24. which is our answer.
2……….
u can write 2/5 in decimals by dividing this . so 2/5 is equal to 0.4
and now u r left with 0.4×60
so after multiplying it comes 24.0
and that is equal to 24. (because after decimal zeros has no value)
3……….
and u also can multiply 2 by 60 . it occurs 120 then devide it by 5 . the answer comes 24.
It’s 0.775x +2.5 =correct
