7d + d - 4d - 7 = 5d

8d - 4d - 7 = 5d

4d - 7 = 5d

5d = 4d - 7

Subtract sides 4d

- 4d + 5d =  - 4d + 4d - 7

d =  - 7

Thus the correct answer is Option three.

It is estimated that the population of the world is increasing at an average rate of 1.09%. The population was about 7,632,819,3
morpeh [17]

Answer:

The equation that represents the population after T years is

P_{t}  = 7,632,819,325 [1 +\frac{1.09}{100} ]^{T}

Step-by-step explanation:

Population in the year 2018 ( P )= 7,632,819,325

Rate of increase R = 1.09 %

The population after T years is given by the formula

P_{t}  = P [1 +\frac{R}{100} ]^{T} -------- (1)

Where P = population in 2018

R = rate of increase

T = time  period

Put the values of P & R in above equation we get

P_{t}  = 7,632,819,325 [1 +\frac{1.09}{100} ]^{T}

This is the equation that represents the population after T years.

Need Help With Math. One Question
alina1380 [7]

Answer: 2 < x < 16

The triangle inequality theorem says that if we have a triangle with sides a,b,c then

b-a < c < b+a

with b being longer than 'a'

In this case, a = 7 and b = 9 and c = x

so we have

b-a < c < b+a

9-7 < c < 9+7 .... replace a with 7, replace b with 9

2 < c < 16

2 < x < 16 .... replace c with x

So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.
