-2x+14y=148*3x+5y=256
(-2x+14y)/148=3x+5y=256/148
(-x+y)37/7=3x+5y=64/37
37*7(x+y)/37=(3x+5y)*37=64/37*37
7(x+y)=111x+185y=64
7x-111x=-7y-185y+64
104x=191y+64
x=191y+64/104
Answer:
8/10
Step-by-step explanation:
8/10 = 80/100 > 63/100
23; 20+4+9+ 28
he can estimate by rounding the numbers
24;19.99+4.19+8.50+27.75=
24.18+ 8.25+28=
24.18+36.25=
$60.43
Answer:
y = 40.96
