Answer:

Conrad worked 11 2/3 hours this week.

Step-by-step explanation:

In order to find the total number of hours that Conrad worked this week, we need to take his total from the week before and multiply it by the increase in time from this week. Seeing the key word 'times' in the problem lets us know that the operation is multiplication. In order to make our multiplication problem easier, we can convert both mixed numbers into improper fractions. 6 2/3 is also 20/3 and 1 3/4 is also 7/4. We can then multiply 20/3 x 7/4, in which case we multiply the numerators together and the denominators together to get: (20 * 7)/ (3*4) = 140/12 = 11 2/3 hours for this week.

Zielflug [23.3K]

Answer-

The value of x is 10

Solution-

When two lines are crossed by another line (transversal), the angles in matching corners are called Corresponding Angles.

When the line are parallel the corresponding angles are equal in measurement.

As m and n are parallel line, so

$\Rightarrow 8x+50=130$

$\Rightarrow 8x=130-50$

$\Rightarrow 8x=80$

$\Rightarrow x=10$
