What is the answer 3 1/3 + 2 1/3

Mathematics

Answer:

5 2/3

Step-by-step explanation:

First add the whole numbers (3+2 = 5).

Then add the fractions. Since they already have common denominators, just add the numerators (1+1 = 2) and the denominator stays the same.

Since the numerator (top of the fraction) is smaller than the denominator (bottom of the fraction) and it can't be simplified, we are done. :-)

Help with this exponential function!
butalik [34]

The population size after 6 years and after 8 years are 147 and 169 population respectively

<h3>Exponential functions</h3>

The standard exponential function is expressed as y = ab^x

where

a is the base

x is the exponent

Given the function that represents the population size P (t) of the species as shown;

p(t)=\frac{550}{1+5e^{-0.1t}} \\

For the population size after 6 years

p(t)=\frac{550}{1+5e^{-0.1(6)}} \\P(6)=\frac{550}{3.744}\\ P(6)=147 population

For the population after 8 years

p(t)=\frac{550}{1+5e^{-0.1(8)}} \\P(8)=\frac{550}{3.2466}\\ P(8)=169 population

Hence the population size after 6 years and after 8 years are 147 and 169 population respectively

Answer:

-4x + 12 = 20 is incorrect. she added 12 to 20 instead of subtracting 12 from both sides.

Step-by-step explanation:

It should have been, write problem

-4(x - 3) = 20

Use distributive property.

-4x + 12 = 20

subtract 12 from each side

-4x =8

divide each side by -4

x = -2
