good luck!
(for x=0) 3 & (for x=4) 19
Answer A
For ease convert both into ounces.
Gross = (11x16) + 5 = 181 ounces
Packaging = (1x16) + 15 = 31 oz.
Now subtract Packaging from Gross
181 - 31 = 150 oz.
Divide by 16 to get pounds
150/16 = 9.375 - hence 9 lb.
and multiply 16 by .375 for ounces
0.375 x 16 = 6 oz.
Thus A : 9lb 6 oz
X + y = 61
y - 3x = 5...y = 3x + 5
x + (3x + 5) = 61
4x + 5 = 61
4x = 61 - 5
4x = 56
x = 56/4
x = 14
y - 3x = 5
y - 3(14) = 5
y - 42 = 5
y = 42 + 5
y = 47
ur 2 numbers are 14 and 47
