1) Given binomials:

First binomial 7r - 5
Second binomial 5r + 8

2) To pass from 7r to 5r you have to subtract 2r, so the first term of the binomial to be subtracted is 2r

3) To pass form - 5 to + 8, you have fo subtract  - 13

4) So the answer is 2r - 13, option b.

Evaluate 9÷3[(20-7)-2^2]
german

Answer:

43

Step-by-step explanation:

You will have to use the PEMDAS rule here. so Parntheses goes first, then exponents, then mutiplicaton or division, and finally addition or subtraction.

20-7= 13

-2^2 = (-2 * -2) = 4

9/3 = 3

so... 13*3 = 39+4 =43

3. Bob the Builder wants to earn an annual rate of 10% on his investments,
mamaluj [8]

Answer:

He should pay $2,790.7.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in years.

After t years, the total amount of money is:

T = E + P

In this question:

Rate of 10%, so I = 0.1.

9 months, so t = \frac{9}{12} = 0.75

How much should he pay for a note that will be worth $3,000 in 9 months?

We have to find P for which T = 3000. So

T = E + P

3000 = E + P

E = 3000 - P

Then

E = P*I*t

3000 - P = P*0.1*0.75

1.075P = 3000

P = \frac{3000}{1.075}

P = 2790.7

He should pay $2,790.7.
