notka56 [123]

Answer:

300 km

Step-by-step explanation:

3 hours and 45 minutes = 3 $\frac{3}{4}$

Speed = 80 km per hour.

80 × 3 = 240 km

80 × $\frac{3}{4}$ = 60

240 + 60 = 300

7(1 - y) = -3(y-2)<br> What is the answer

Fynjy0 [20]

Answer:

$\huge y = \frac{1}{4}$

Step-by-step explanation:

$7(1 - y) = -3(y-2)$

<u>Expand the terms in the bracket</u>

That's

$7 - 7y = - 3y + 6$

<u>Add 3y to both sides of the equation</u>

$7 - 7y + 3y = 3y - 3y + 6 \\ 7 - 4y = 6$

Subtract 7 from both sides by the equation

$7 - 7 - 4y = 6 - 7 \\ - 4y = - 1$

<u>Divide both sides by - 4</u>

$\frac{ - 4y}{ - 4} = \frac{ - 1}{ - 4} \\$

We have the final answer as

$y = \frac{1}{4} \\$

Hope this helps you

A crew is made up of 8 men; the rest are women. If 32 % of the crew are men, how many people are in the crew?

Lelechka [254]

Answer:

12

Step-by-step explanation:

(66 2/3)

---------- (x) = 8

100

Solve for x

(66 2/3)x = 800

x = 800/(66 2/3)

x = 800/(200/3)

x = 800(3/200)

x = 4(3)

x = 12
