Step-by-step explanation:
Given


Required
Solve for x and y
Make x the subject in the second equation

Substitute 31 - 5y for x in 



Collect like terms


Solve for y


Substitute 6 for y in 



When dividing fractions we "invert and multiply".
First we should change 2 (5/16) to 37/16.
So, 37 / 16 divided by 7 / 8 equals
37 / 16 times 8 / 7
which equals 296 / 112 = 37 / 14 which equals
2 (9/14)
Answer:
<u>6 kg</u>
Step-by-step explanation:
J = mass of nuts gathered by James
H = mass of nuts gathered by Harry
J = 12 + H
J = 3H
3H = 12 + H
3H - H = 12 + H - H
2H = 12
H = 6 kg
J = 18 kg
=4m - 17+ 3m - 11
combine like terms
=(4m + 3m) + (-17 - 11)
=7m - 28
This can be factored/simplified by dividing everything by 7
=7(m - 4)
Hope this helps! :)
