<span>which answer is equal to 2√-28?
basically, this question wants you to simplify 2</span>√-28. find a perfect square that you can pull out of -28: -4 works just fine.

2√-28 = 2√(-4 · 7)i ... take the √-4 out. the root of -4 is 2i
2(2i)√7... multiply 2*2i
4i√7 is your result. <span>

which answer is the solution to √2x-7 - √x = 1 ?
i've tried, like, every method i know of for this problem and for some reason my answer keeps getting messed up. i entered it into my calculator and got x = 16, so i assume that's your answer, but i'm sorry i couldn't show you any work for it.</span>

Calculate the moment of the 250 n force on the handle of the monkey wrench
vivado [14]
We are given with
250 N force
F = 250 N
The usual monkey wrench has a length of 11 cm or 0.11 m
d = 0.11
Therefore, the moment is
M = F d
M = 250 (0.11) = 27.5 N m

abruzzese [7]

Answer:

Soccer = 120

Tennis = 220

Step-by-step explanation:

The total number of students enrolling for soccer and tennis classes is, 340.

The ratio number of students enrolling for soccer and tennis classes is, 6:11.

Then,

6x + 11x = 340

17x = 340

x = 20

The number of students enrolled for soccer class is, 6x = 6 × 20 = 120.

The number of students enrolled for tennis class is, 11x = 11 × 20 = 120.

larisa [96]

Answer:

2

Step-by-step explanation:

You can find slope using the slope equation :\frac{y2-y1}{x2-x1}

  • Plug in the two points : \frac{4-(-18)}{4-(-7)}
  • Calculate by adding the numbers: \frac{22}{11}
  • Reduce the fraction : 2

The slope is 2

Tell whether the given number is a solution of each question. ( Must show work for credit)
guajiro [1.7K]

Answer/Step-by-step explanation:

1. 9 = 2a + 3 ; 3

Let's solve for a.

9 - 3 = 2a (subtraction property of equality)

6 = 2a

\frac{6}{2} = a (division property of equality)

3 = a

a = 3

Therefore, 3 is a solution to 9 = 2a + 3

2. 5n - (-30) = 5 ; 7

5n + 30 = 5 (- × - = +)

5n = 5 - 30 (Subtraction property of equality)

5n = -25

\frac{5n}{5} = \frac{-25}{5} (division property of equality)

n = -5

Therefore, 7 is not a solution of 5n - (-30) = 5

3. 4.4r - 2.8 = 1.6 ; 1

4.4r = 1.6 + 2.8

4.4r = 4.4

\frac{4.4r}{4.4} = \frac{4.4}{4.4}

r = 1

Therefore, 1 is a solution of 4.4r - 2.8 = 1.6.
