Answer 2
Answer:

Answer:

3 3/4.

Step-by-step explanation:

Add the whole number first.

  • 1.

Then, add 3/4 3 times.

  • you have 9/4.
  • 1 + 9/4 = 3 1/4

Simplify:

  • 1 + 2 1/4 = 3 1/4

We now use 2/4 once.

  • 3 1/4 + 2/4 = 3 3/4.

There are 100 numbers that begin with 3. In the other 200, there are effectively a tenth ending in 3. That is, 120 total numbers.

4x²+8x=1 by completing the square

Answers

First thing you do is subtract both sides by 1.
Then divide everything by 4, to remove the 4x².
After completing the square, you multiply the 4 back in.

How do i do the equation 2+6 divided by 3 divided by 1 with an exponent of 8?

Answers

Answer:

4

Step-by-step explanation:

First you need to evaluate the power (exponent).

1 raised to any power is still 1.

Then you need to divide the equation

2 + 6 ÷ 3 ÷ 1

2 + 2

4

Answer:

Step-by-step explanation:

To solve this problem you should follow the PEMDAS rule, which is parentheses, exponents, multiplication, division, addition, and subtraction.

The work of a student to solve a set of equations is shown:Equation 1: m = 8 + 2n
Equation 2: 3m = 4 + 4n



Step 1:
−3(m) = −3(8 + 2n) [Equation 1 is multiplied by −3.]
3m = 4 + 4n [Equation 2]

Step 2:
−3m = −24 − 6n [Equation 1 in Step 1 is simplified.]
3m = 4 + 4n [Equation 2]

Step 3:
−3m + 3m = −24 − 6n + 4n [Equations in Step 2 are added.]

Step 4:
0 = −24 − 2n

Step 5:
n = −12


In which step did the student first make an error?

Step 2

Step 1

Answers

Answer:

Step 3

Step-by-step explanation:

Hello

the student made a mistake in the step number 3.

let´s see

in the step number 1 he multiplied by -3 in order to add this new equation with  equiation 2 and then eliminate the terms with m

Step one

-3(m)=-3(8+2n)

-3m= -24 - 6 n,  it is ok

in step two he simplified, he did it well.

in the step 3  he added the equations

 -3m = -24-6n

  3m = 4   +4n

_____________

    0   = -20-2n

he did not add properly -24+4, here , he made his first mistake.

step 4 is already wrong

continuing..to find n

0= -20-2n

20=-2n

n=-10

Have a great day

 

I think the student first made an error on step 1 because why is it multiplied by -3. To be more precise, where did the student get the -3 from?

Suppose the volume of milk in a glass is 230 cubic cm. If 1 gallon of milk equals 3.79 liters, how many glasses of milk are in 1 gallon

Answers

1 liter= 1 dm³=1000 cm³
230 cm³ = 0.23 dm³ = 0.23 lit.
If 1 gal= 3.79 lit.:
3.79 : 0.23 = 16.478 glasses of milk
