I'd suggest getting a Texas Instruments TI-84 plus calculator or use des mos .com scientific
Y= (x(9/5)) + 32; Ex: y=(100(9/5)) + 32 —> 100 x 1.8 (or 9/5) = 180–> 180 + 32= 212 F
I'm pretty positive it would be the second one from the top
answer = the elder bother is 17 and the younger one is 15
constructive odd integers= 15 and 17
17×15= 255
255+38 = 293
Square root of 293 = 17
-3x+4=-17
subtract -4 from both sides
divide -3 from both sides
the answer is 7
