Help- i suck at math bro-

Sedbober [7]

Answer:

x = 2. The answer is 2

Step-by-step explanation:

You don't have to use the tiles if you don't want to... I didn't use the tiles. Ok so,

In order to get x by itself you need to first add 5 to both sides. Once you do that it should look something like this

4x-5 +5 = 3+5

-5 and +5 both cancel out just leaving you with 4x, and 3+5=8. So now it should look like this.

4x = 8

Now, you just have to divide 4 to both sides

4x/4 = 8/4

Both 4's cancel out leaving you with x and 8 divided by 4 equals to 2.

x = 2

TAADAA!!

I hope this helps! Have a good day!

P.S

No one sucks at math dude you just gotta practice lol :D

How can you write the equation for a linear function if you

topjm [15]

Use the two ordered pairs to find the slope. first label the point x1, y1 and the second set x2, y2. then you do y2 - y1/ x2-x1 and simplify that fraction if necessary

The population of Cuba is 1.3 million. The country's population is expected to grow at a rate of 4% each year.

Darya [45]

The population growth will be modeled using exponential growth:
f(x)=a(b)^t
where:
a=initial value
b=growth rate
thus plugging in the values we get:
f(x)=1.3(1.04)^t
thus the population after 10 years will be:
f(x)=1.3(1.04)^10
f(x)=1.9243
thus the population in 10 years will be:
1.9243 million

A container is in the shape of the rectangular prism shown. Stan measures the length of PS as 12 feet, the length of SR as 9 fee

ArbitrLikvidat [17]

Answer:

The distance from point P to point V = 17 ft.

Step-by-step explanation:

A rectangular prism is simply a cuboid,

The image describing the cuboid described, as obtained from from internet is attached to this solution. (It is redrawn to avoid the solution being removed due to violation of community guidelines)

From the image, PR, PS and SR form a right angled triangle on the case of the cuboid.

With PR as the hypotenuse side, using Pythagoras theorem,

(PR)² = (PS)² + (PR)²

(PR)² = 12² + 9² = 144 + 81 = 225

PR = √225

PR = 15 ft.

On a second evaluation, the required length, PV, PR and RV form another right angled triangle with PV as the hypotenuse side, using Pythagoras theorem again,

(PV)² = (PR)² + (RV)²

(PV)² = 15² + 8² = 225 + 64 = 289

PV = √289

PV = 17 ft.

Hope this Helps!!!
