Answer:

-3ad/2 -2bd = c

Step-by-step explanation:

3a + 4b = 1 - 2c/d

⇒3ad + 4bd = d - 2c         [multiply d on both sides]

⇒3ad + 4bd - d = -2c         [subtract d on both sides]

⇒3ad/(-2) + 4bd/(-2) = c      [divide -2 on both sides]

⇒-3ad/2 -2bd = c

Answer:

Substitute point (4, 8)

y = y1 + m(x - x1)

y = 8 + m(x - 4)

y = 8 + mx - 4m

let m = 3 (It can be anything) Substitute m into equation:

y = 8 + (3)x - 4(3)

y = 2x - 4

Please I need answer right now ppleassssee<br><br>D. -1/4+-2/3<br>with explanation pleaseeee​
Masja [62]

Answer:

1 - 1/3

Step-by-step explanation:

Since 1/2 * 2/3 = 1/3, it should be the case that 1/3 divided by 2/3 gives 1/2 and that 1/3 divided by 1/2 gives 2/3. To divide fractions, we multiply the numerator by the reciprocal of the denominator, where the reciprocal of a number just interchanges the numerator and denominator of the number.

spin [16.1K]

Answer:

B. 28 hours

Step-by-step explanation:

GIVEN :- <em>Time taken by family to travel 600 km is 8 hours</em>

CALCULATIONS :-

<em>To calculate the time to travel 2100 km, we need to calculate distance traveled in 1 hour</em>

<em>Distance traveled in 1 hour = 600 km ÷ 8</em>

<em>                                              = 75 km</em>

<em>Time required to travel 2100 km = 2100 ÷ 75</em>

<em>                                                         = </em><em>28 hours</em>

Therefore time required to travel 2100 km is 28 hours.
