Estimate 4427 -3013 by first rounding each number to the nearest hundred.

Step-by-step explanation:

Round the values to the nearest hundred.

4427 -> 4400

3013 -> 3000

Estimate:

4400 - 3000 = 1400

1400

Step-by-step explanation:

4400-3000 = 1400

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
