Answer:

So the next time they will leave together is 4:24 pm

Step-by-step explanation:

Since both the buses left at 4 pm and red line bus leaves every 6minutes and blue line bus leaves every 8 minutes they next time they leave together can be found by taking the L.C. M of 6 and 8.

The L.C. M is found by multiplying all the factors and chosing one which common in both numbers.

Factors of 6 = 2<u>*3</u>

Factors of 8= 2<u>*2*2</u>

In these numbers 2 is common in both.The rest of the numbers( 2*2*3 )are multiplied with the the common 2 to get the L.C.M

L.C.M= 2*2*2*3= 24 minutes

So the next time they will leave together is 4:24 pm

<h3>Answer:</h3>

<h3>Explanation:</h3>

The distributive property is useful both for collecting terms and for eliminating parentheses.

1. 3x +1/4 -x +1 1/2 = x(3 -1) +(1/4 +1 2/4) = 2x +1 3/4 ≠ 4x +1 3/4 (no)

2. 2(3x+1) = 2·3x + 2·1 = 6x +2 = 2 +6x (yes)

3. 3(x+1) -(1+x) = (x+1)(3 -1) = 2(x+1) = 2x +2 ≠ 2x +3 (no)

4. 4(x+1)-x-4 = 4x +4 -x -4 = x(4-1) +(4-4) = 3x +0 = 3x (yes)

5. 5.5 +2.1x +3.8x -4.1 = x(2.1 +3.8) +(5.5 -4.1) = 5.9x +1.4 = 1.4 +5.9x (yes)

$\frac{2(a^{2})^3 }{-10a^{-8} } =\frac{2a^6}{-10a^{-8} } = \frac{-1}{5} a^{6--8} =\frac{-1}{5} a^{14}$

Hope that helps!

Convert 7x + 3y = −1 to slope-intercept form.

maksim [4K]

Hi there!

Let's solve this problem step by step!

$7x + 3y = - 1$
To convert this formula to slope-intercept form, we must isolate y.

First bring 7x to the left by subtracting 7x from both sides of the equation.
$3y = - 7x - 1$

Finally we need to divide both sides of the equation by 3.
$\frac{3y}{3} = \frac{ - 7x - 1}{3}$

Do some simple algebra and we find:
$y = - \frac{7}{3} x - \frac{1}{3} \\ y = - 2 \frac{1}{3} x - \frac{1}{3}$
~ Hope this helps you!
