Answer:

a+b=6.....(1)

a-b=2.......(2)

Adding equiation (1)&(2), we get

2a=8

a=4

putting value of a in equiation (1), we get

4+b=6

b=6-4=2

therefore a=4 and b=2

If one redskin and 4 golden roughs cost $1.65, whereas 2 redskins and 3 golden roughs cost $1.55, how much does each type or swe
Bas_tet [7]

Answer:

Redskins cost $0.25 and golden roughs cost $0.35.

Step-by-step explanation:

Let r be the cost of a redskin and g the cost of golden roughs. So we have the system of equations:

r + 4g = 1.65

2r + 3g = 1.55

Multiply the first equation by -2:

-2r - 8g = -3.30

Adding this to the second equation:

-5g = -1.75

g = 0.35.

Now substitute this into the first equation:

r + 4*0.35 = 1.65

r  = 1.65 - 1.40

r = 0.25.

Terry deposits $200 into a bank account that earns 3% simple interest per year. What is the total amount in the account after 2
MrRa [10]
Well first you have to solve for the 1st year so 200*.03, .03 represents the 3%. Which would equal 6 dollars so after the 1st year he would have 200+6=206.

Now you do the second year so do 206*.03, which would equal 6.18 so 206+6.18=212.18

Answer= 212.18
