Which point on the number line best represents√57?

Mathematics
1 answer:
Cerrena [4.2K]3 years ago
7 0

Answer:

8.

Step-by-step explanation:

\sqrt{57} =\sqrt{3 * 19}

Since this cannot be further simplified, we will calculate the square root of 57 with our calculators.

We find that the square root of 57 is 7.549834435, and since the tenths place is a 5, we will round up to the next whole number. So, the point on the number line that best represents the square root of 57 is 8.

Hope this helps!

Question 1. 5b + 2 = 17

Step 1. Subtract 2 from both sides of the equation.

5b+2-2=17-2

Step 2. Then simplify.

5b=15

Step 3. Finally divide by 5.

5b/5=15/5

Answer: b=3

Question 3.

Step 1. Subtract 9 from both sides.

9+4b-9=17-9

Step 2. And simplify.

4b=8

Step 3. Finally divide by 4.

4b/4=8/4

Answer: b=2

Hope this helps! :)

Determine whether the systems have one solution, no solution, or infinitely many solutions
Lerok [7]

Answer:

First system: no solution

Second system: one solution

Third system: one solution

Fourth system: infinite solutions

Fifth system: no solution

Step-by-step explanation:

First system: 3x-2y=3; 6x-4y=1

From the first equation: y = (3x - 3)/2

Using this value of y in the second equation:

6x - 6x + 6 = 1

6 = 1 -> System has no solution

Second system: 3x-5y=8; 5x-3y=2

From the first equation: x = (8 + 5y)/3

Using this value of x in the second equation:

5*(8 + 5y) - 9y = 6

40 + 25y - 9y = 6

16y = -34 -> y = -2.125

x = (8 - 5*2.125)/3 = -0.875

This system has one solution

Third system: 3x-2y=8; 4x-3y=1

 From the first equation: x = (8 + 2y)/3

Using this value of x in the second equation:

4*(8 + 2y) - 9y = 3

32 + 8y - 9y = 6

y = 26

x = (8 + 2*26)/3 = 20

This system has one solution

Fourth system: 3x-6y=3; 2x-4y=2

  From the first equation: x = 1 + 2y

Using this value of x in the second equation:

2*(1 + 2y) - 4y = 2

2 + 4y - 4y = 2

2 = 2

This system has infinite solutions

Fifth system: 3x-4y=2; 6x-8y=1

  From the first equation: x = (2 + 4y)/3

Using this value of x in the second equation:

2*(2 + 4y) - 8y = 1

4 + 8y - 8y = 2

4 = 2

This system has no solution
