Answer:

the number is 4

Step-by-step explanation:

Hello,I think I can help you with this

Step 1

convert into mathematical terms

let x the unknown number

three more: 3 +

twice the sum of 7 and a number:2(7+x)

is 25:=25

Hence

3+2(7+x)=25

Step 2

Now, solve for x

3+14+2x=25

17+2x=25

2x=25-17

2x=8

x=8/2

x=4

the number is 4

Do not hesitate to ask me if you have any concerns

Have a great day.

More means add so you add 3+
then you multiply 2
so now you have 3 + 2 x 7= 25
you can check it by doing 3 + 2= 5 x 7=25

A regular section of land made up of wheat farms has a length of 5x10^4 and the width of 6x10^3 what is the area of the length i

Fudgin [204]

Answer:

The Area of land is 30 × $10^{7}$ meters² .

Step-by-step explanation:

Given as :

The length of rectangular wheat farm land = L = 5 × $10^{4}$ meter

The width of rectangular wheat farm land = w = 6 × $10^{3}$ meter

Let The Area of land = A meters²

Now, According to question

∵ Land is in rectangular shape

And we know, Area of rectangle = length × width

∴ Area of land = Area of rectangle = length × width

Or, A = L × w

Or, A = 5 × $10^{4}$ meter × 6 × $10^{3}$ meter

Or , A = 30 × $10^{4+3}$

i.e A = 30 × $10^{7}$ meters²

So, The Area of land = A = 30 × $10^{7}$ meters²

Hence,The Area of land is 30 × $10^{7}$ meters² . Answer

This is algebra 2 it’s growth & decay. I need help

Elodia [21]

So firstly, remember that the <em>a variable is the initial value.</em> Since we start off with 6.08 billion, <u>6.08 billion is the a variable.</u>

Next, since this is a <em>growth by 1.26%</em>, add 1 and 0.0126 (1.26% in decimal form) together to get 1.0126. <u>1.0126 is the b variable.</u>

Putting it together, <u>the function is $A(t)=6.08(1.0126)^t$ </u>

Since 2020 is 20 years from 2000, plug in 20 into the t variable of the prior function to solve:

$A(20)=6.08(1.0126)^{20}\\ A(20)=7.81$

In context, <u>in 2020 the population will be 7.81 billion.</u>
