How can square roots be written so that the radicand has no square factors?
larisa86 [58]

Answer:

You can do this by dividing the radicand by the square number , and multiplying the radical by the root of that number.

e.g.

\sqrt{96} \\= \sqrt{16 \times 6}\\= 4\sqrt{6}

Julie and Eric row their boat (at a constant speed) 55 miles downstream for 5 hours, helped by the
Archy [21]

Answer: C = 3 mph is the rate of the current.

Step-by-step explanation:

Hey there!

<u />

<u>You can use the distance formula (d = rt) to solve this problem.  </u>

Downstream trip: d = 55 miles, t = 5 hours, and r = R + C  

R + C is their rowing speed (R) plus the rate of the current (C).  

Upstream trip: d = 55 miles, t = 11 hours, and r = R - C

R - C is their rowing speed (R) minus the rate of the current (C).  

Downstream: 55 mi. = (R + C)5 hrs. Divide both sides by 5: R + C = 11

Upstream: 55 mi. = (R - C)11 hrs. Divide both sides by 11: R - C = 5

<u>Calculations</u>

R + C = 11 Subtract C from both sides.

R = 11 - C Substitute this into: R - C = 5

(11 - C) - C = 5 Simplify and solve for C

11 - 2C = 5 Add 2C to both sides.

11 = 2C + 5 Subtract 5 from both sides.

6 = 2C Divide both sides by 2

C = 3 mph is the rate of the current.

~I hope I helped you! :)~

Write the equation in​ slope-intercept form. Then find the slope and​ y-intercept of the line.
alisha [4.7K]
Learn this...it helps

HOY -- horizontal line, 0 slope, represented by y = a number
VUX -- vertical line, undefined slope, represented by x = a number.

so ur equation y = -1....this is a horizontal line with a 0 slope
In slope intercept form it is : y = 0x - 1 <==....ur slope is 0 and ur y int is -1

What is the value of x in the equation 2x+3y=36y when y=6?
jonny [76]

Answer:

y = 6 so

2x + 3y = 36y is equal to:

2x + 3*6 = 36*6

-> 2x + 18 = 216

We must now move 18 to the other side of the equation. As we do that, we also change it's sign to negative 18:

2x = 216 - 18

We simplify this

2x = 198

Now, that we got to this point, we know that 2x is equal to 198. To find x we must divide the both sides of the equation by two:

2x/2 = 198/2

And we get that

x = 99

Step-by-step explanation:
