Answer:
Thomas has 45
Emma 30+45=75 pound
Step-by-step explanation:
Ratio is 3/5
Tomas receives x money
Emma receives x+30
3/5=x/30+x
3(30+x)=5x
90+3x=5x
90=5x-3x
90=2x
x=90/2=45
Thomas has 45
Emma 30+45=75 pound
45/75=3/5
Answer: 25 nickels
Step-by-step explanation:
EQUATIONS:
quantity: n + d = 63
value: 5n + 10d = 505
-------------------------
Divide thru the 2nd equation by 5 to get:
n + 2d = 101
----------------
Subtract that from the 1st equation:
-d = -38
d = 38 (# of dimes)
---------------
Substitute that into n+d=63 to solve for "n":
n + 38 = 63
n = 25 (# of nickels)
