Answer:

1.a. 5(x-6)

2.d=k-9

3.c.10 x+5

4.c.The quotient of some number and six.

5.a.The quotient of three times some number and five

6.b.x^5

Step-by-step explanation:

1.We are given that verbal expression ''five times the difference of a number and six''

We have to find its algebraic expression

Let x be the number

Difference of x and 6=x-6

We are multiplying  difference of x and 6 by 5

Then we get

5(x-6)

Option a is true

2.Verbal expression ''nine less than some number ''

Let k be the some number

Nine less than some number k

=k-9

Option d is true.

3.Five more than the product of ten and some number .

Let x be the some number

Product of 10 and some number x

Then we get 10 x

Now, 5 more than the product of 10 and x

Then, we get an algebraic expression

10 x+5

Hence, option c is true.

4.Given algebraic expression

Fraction with variable x in numerator and 6  in  the denominator .

We have to find its verbal expression

The quotient of some number and six.

Hence, option c is true.

5.We are given that an algebraic expression

3x\div5

We have to find its verbal expression

The quotient of three times some number and five

Where x is some number in algebraic expression.

Hence, option a is true.

6.We are given that verbal expression

''Some number to the power of 5''

We have to find the algebraic expression

Let x  be the some number

Then , the algebraic expression

x^5

Hence, option b is true.

ioda

a. Life span increased

b. The median age could rise because of the improvement in medical technology. Also more advertisement of healthier life styles, such as eating healthy could have increase the median age.

c. No because this just shows the increase in life span not the decrease in children.

Step-by-step explanation:

a. more people on average lived longer lives. (explanation)

b. self explanatory I guess, my answer pretty much explained it.

c. life span of US citizens does not effect the children population. I guess you could say people lived longer lives to have more children, so possibly the number of children could have increased.

42. Nathan bought a new computer for $875. He
Aleksandr-060686 [28]

Answer:

5%

Step-by-step explanation:

The equation for simple interest rate is as follows:

A = P(1+rt)

A = final amount

P = initial principal amount

r = annual interest rate

t = time (in years)

So, we need to plug everything in and solve for r:

The final amount is equal to $875 plus the interest of $131.50.

A = 875 + 131.50 = 1006.50

Now, plug everything in:

1006.50 = 875( 1 + r(3))

Solve:

1 + 3r = 1.15028571                            Divide 1006.50 by 875

3r = 0.15028571                                Subtract 1 from 1.15028571

r = 0.050                                           Divide by 3

The simple interest rate would be 5%. I converted the r to a percent by multiplying 0.050 by 100.

I hope this helps!! Ask questions if you need!!
