Answer: The required length by which the elephant grows in 8 days is $18\dfrac{2}{3}~\textup{inches}.$

Step-by-step explanation: Given that an elephant grows $2\dfrac{1}{3}$ inches a day.

We are to find the length by which it grow in 8 days.

We will be using the UNITARY method to solve the given problem.

In 1 day, the length by which the elephant grow is

$2\dfrac{1}{3}=\dfrac{7}{3}~\textup{inches}.$

Therefore, the length by which the elephant grow in 8 ways is given by

$\dfrac{7}{3}\times8=\dfrac{56}{3}=18\dfrac{2}{3}~\textup{inches}.$

Thus, the required length by which the elephant grows in 8 days is $18\dfrac{2}{3}~\textup{inches}.$

What is the solution to this equation? 4x+x-15+3-8=13

deff fn [24]

Answer:

x = 33/5

Step-by-step explanation:

4x+x-15+3-8=13

Combine like terms

5x -20 = 13

Add 20 to each side

5x-20+20 = 13+20

5x =33

Divide by 5

5x/5 = 33/5

x = 33/5

Isabel can drive 505.85 miles with a gas tank that holds 15.1 gallons of gas

<em><u>Solution:</u></em>

Given that, Isabel’s car gets 33.5 miles per gallon

Her gas tank holds 15.1 gallons of gas

To find: Number of miles can Isabel drive on a full tank of gas

Let "x" be the miles drive with 15.1 gallons of gas

From given,

1 gallon = 33.5 miles

15.1 gallon = x miles

This forms a proportion and we can solve the sum by cross multiplying

$1 \times x = 15.1 \times 33.5\\\\x = 505.85$

Thus Isabel can drive 505.85 miles on a full tank of gas

Can someone help me on this

Cerrena [4.2K]

Answer:

2x+h

Step-by-step explanation:

f(x+h) means that wherever there's an x in the function f(x) we plug in a x+h

we have

(x+h)²+9

Let's start with the numerator

(x+h)²+9-(x²+9)

Distribute the exponent

x²+2xh+h²+9-x²-9

Which gives us

2xh+h²

Divide the whole thing by h to give us

2x+h
