Answer: 8/14, 12/21, and 288/504

Step-by-step explanation: To find 3 fractions that are equivalent to 4/7, we either multiply or divide the numerator and denominator by the same number.

If we multiply 4/7 by 2 in both the numerator and denominator, we get the equivalent fraction 8/14.

If we multiply 4/7 by 3 in both the numerator and denominator, we get the equivalent fraction 12/21.

If we multiply 4/7 by 72 in both the numerator and denominator, we get the equivalent fraction 288/504.

These are just 3 possible answers.

I need to solve for x. The interior angles are 30 and 4x+2. The exterior angle is 8+6x.
alexira [117]

Answer:

x + y + z = 180 (this is the first equation)

w + z = 180 (this is the second equation)

Now, rewrite the second equation as z = 180 - w and substitute that for z in the first equation:

x + y + (180 - w) = 180

x + y - w = 0

x + y = w

A taxi hurries for 1 hour 54min with a constant speed of 93km and then for another 5 hours 15min with a constant speed of 72km.
Ghella [55]

Speed  = 93km /h  and  72km/h

Answer: The taxi went a distance of 554.7km

Step-by-step explanation:

Speed  = Distance / Time

Distance covered in the first trip = Speed x Time

Time = 1 hour 54 min =1+0.9 hours  =1.9hours

=93km / h x 1.9 hours =176.7km

Distance covered in the second  trip = Speed x Time

Time = 5 hours 15min = 5+0.25hours  =5.25hours

=72km / h x 5.25hours =378 km

Total distance =176.7km+378 km

=554.7km
