Subtract the second equation from the first

8x-4y=-4

-(-3x+4y=5)

Find the amount after one year on $1,000 invested at 6% per year if interest is simple interest

Olenka [21]

Answer:

The amount after 1 year is $ 1060 .

Step-by-step explanation:

The amount after 1 year on $1,000 invested at 6% per year on simple interest

is given by,

$ $1000 \times (1 + \frac{6}{100})$

= $ (1000 + 60)

= $ 1060

We know that, if,

Principal = P unit

Rate of annual simple interest = R%

Time = T year

then, amount, A = $(P \times( 1 + \frac {R \times T}{100}))$ unit

If 2a + b = 13 and 3c-6a = 5, what is the value of b + c?

ElenaW [278]

Step-by-step explanation:

Solve the first eqn for b, b=13–2*a, and the 2nd for c, c=(6*a+5)/3. Then

b+c=13–2*a+(6*a+5)/3=13–2*a+2*a+5/3=44/3. We see that b+c has a definite value because the terms in a cancel.
