Answer:
100 silver coins and 175 bronze
Step-by-step explanation:
let x be the number of silver coins and y the number of bronze coins.
Worth of these coins together = 6x/(5)+0.08/(10)y
=1.2x+0.008y
Weight of one silver coin = 125/5 = 25 gm
and one bronze coin = 500/10 = 50 gms.
Weight of these coins together = 25x + 50y
Equate these two items i.e. value and weight to actuals given.
i.e. 1.2x+0.08y = 134 and ... i
25x+50y = 11 kg 250 gm = 11250 gms. ... ii
Divide the second equation by 25
x+2y = 450 ... iii
Multiply I equation by 25
30x+2y =3350 ... iv
iii-iv gives -29x = -2900 or
x =100
Substitute in x+2y = 450
2y = 350 or y =175
18. equivalent
16x5 does equal 10x8
19. equivalent
13-0 does equal 0
20. Not equivalent
12-2 doesn’t not equal 7-3
For all three of these equations you have to use PEMDAS (systems of equations) so first you solve everything that’s in parentheses, then any exponents, followed by multiplication,division,addition, and lastly subtraction. You MUST follow that order to get the correct answer.
11/12 has a greater value than 5/6
