Bronze is an alloy of copper and tin. If a certain type of bronze requires 0.3
kilogram of tin per 1.0 kilogram of copper, how much tin must be combined with
50 kilograms of copper?
kilogram

15 kilograms

Step-by-step explanation:

if 0.3 kilograms of tin is for 1.0 kilograms of copper

You will multiply 0.3 with 50

since 1 kg requires 0.3

so you will need 15 kg of tin for 50 kg because you are multiplying 50 by 0.3

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
