Lin solved the equation 8(x−3)+7=2x(4−17)
incorrectly. Find the errors in her solution. What should her answer have been?

Lin's solution:

8(x−3)+7=2x(4−17)
8(x−3)+7=2x(13)
8x−24+7=26x
8x−17=26x
−17=34x
−12=x

Katie wants to collect over 100 seashells. she already has 34 seashells in her collection. each day, she finds 12 more seashells on the beach. katie can use fractions of days to find seashells. write an inequality to determine the number of days, dd, it will take katie to collect over 100 seashells.

Maddie's rectangular kitchen has an area of 10 square yards and a length of 3 3/4 yards.how many yards wide is maddie's kitchen?

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
