a toy maker is making mini 3 wheel & 4 wheel all terrain atvs. he has a total of 61 wheels and 17 sets of handle bars. how many 4 wheel atvs can he make?

let x be no. of 4-wheel and y be no. of 3-wheel ATVs

so

x+y=17 (each has one set of handlebars)

4*x + 3*y = 61

4*(x)+3*(17-x)=61

x=61-51=10

y=17-10=7

thus x=10 and y=7 and that's your answer

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

ab will be equal to
