nekit [7.7K]

Answer:

D

Step-by-step explanation:

The expression is  (9-7*3+4)^2

We can follow the rule of "PEMDAS" here.

PEMDAS = Parenthesis, Exponents, Multiply, Divide, Add, Subtract

So, we first need to deal with Parenthesis. Next,

There aren't any exponents, so we deal with Multiplication of 7 and 3.

Then addition/subtraction.

Hence, the first step, from the answer choices, would be D, multiply 7 and 3

The cost per week of running a boarding house is partly constant and partly
patriot [66]

Answer:

the cost of running the boarding

house for 600 students is N61,000

Step-by-step explanation:

Let C represents cost

K1 represents first constant

K2 represents second constant

C= k1+k2n

3500 = k1 + 25 k2............. Eqn(1)

6000= k1 + 50 k2 .............. Eqn(2)

Subtract eqn(1) from eqn(2)

2500= 25k2

K2= 2500/25

K2= 100

To get k1 from eqn(1)

3500 = k1 + 25 k2

Substitute the value of k2

3500 = k1 + 25 (100)

3500= k1 +2500

K1= 3500- 2500

K1= 1000

The equation connecting them;

C= 1000+ 100n

The cost of running the boarding

house for 600 students is

n= 600

C= 1000+ 100(600)

C= 1000+60000

C= N 61,0000
