-7.12 = -4.8+× what is the answer?

Answers

You need to get the variable by itself, right? To do that, you need to get rid of the -4.8, and to do that, you need to add 4.8 to each side. -4.8 + 4.8 is 0. -7.12 + 4.8 is -2.32 (because you're adding them; however, since the number with the negative is larger, you keep the sign).

Your answer is -2.32

Don't forget to choose which answer is Brainliest!

Simplify both sides of the equation

-7.12 = x-4.8

Flip the equation

x - 4.8 = -7.12

Add 4.8 to both sides

x-4.8+4.8 = -7.12 + 4.8

x = -2.32

y=8
My steps may be really weird, but please don't ridicule me. 

1. 11+21

BRAINLIEST IF YOU EXPLAIN! A group of students is arranging squares into layers to create a project. The first layer has 5 squares. The second layer has 10 squares. Which formula represents an arithmetic explicit formula to determine the number of squares in each layer?

f(1) = 5; f(n) = 5 ⋅ d(n − 1), n > 0
f(1) = 5; f(n) = 5 ⋅ d(n + 1), n > 0
f(1) = 5; f(n) = 5 + d(n − 1), n > 0
f(1) = 5; f(n) = 5 + d(n + 1), n > 0

Answers

Answer:

f(1) = 5; f(n) = 5 + d(n − 1), n > 0

Step-by-step explanation:

Given

f(1) = 5

f(2) = 10

Required

Determine f(n)

From the formulas in the option, we understand that the sequence is Arithmetic.

And will be determined using

f(n) = a + (n - 1)d

Where a = f(1) = 5

Substitute 5 for a,

f(n) = 5 + (n - 1)d

Or

f(n) = 5 + d(n - 1)

To test,

Take n = 2

d = f(2) - f(1) = 10 - 5 = 5

So, we have

f(n) = a + (n - 1)d

f(n) = 5 + (2 - 1) * 5

f(n) = 5 + 1 * 5

f(n) = 5 + 5

f(n) = 10

Hence,

Option B answers the question.

Answer:

The person who answered above meant to say that it was C not B.

Step-by-step explanation:

His answer was (1) = 5; f(n) = 5 + d(n − 1), n > 0 and this would have been c not b. B would have been f(1) = 5; f(n) = 5 ⋅ d(n + 1), n > 0 which is incorrect.

It takes 21 minutes for 5 people to paint 7 walls. how many minutes does it take 3 people to paint 5 walls. Please help.

Answers

It would take 15 minutes.
21/7=3
5/3=1.666666666667
1.6666666667*3=approx. 5
5*3=15 
Hope it hepls :)
It would take 15 minutes.
21/7=3
5/3=1.666666666667
1.6666666667*3= 5
5*3=15 

So if you do 21 divied by 7 that equals 3. then you do 5 divied by 3=1.666666666667 you divide the 3 bc that's the answer you got for 21/7. then you do 1.666666666667 x3. bc you had that answer for the last problem. then you just have 2 multiply 5x3 and that equals 15.

What is the area of a rectangle with the height of 25mm, and the length of 12mm? After you get the product, turn it into feet.

Answers


Area = (length) x (width) = (25mm x 12mm) = 300 square millimeters

You can't convert 'square millimeters' to feet.  One is a unit of area,
but the other is a unit of length.

You can convert square millimeters to square feet, though.

(300 mm²) x (1 ft / 304.8 mm)²  =  0.00323 square foot (rounded)

300 feet is the answer
