Type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar(s). jenny, who rides a moped, takes 2 hours less to travel 60 miles than maureen takes to travel 50 miles on her bicycle. jenny travels 10 miles per hour faster than maureen. (hint: speed = distance ÷ time.) jenny’s speed is miles per hour. maureen’s speed is miles per hour.

How many real and imaginary solutions does the equation x^2-3x=-2x-7 have?

If the speed of an electromagnetic wave is 100,000 cm/s and its wavelength is 100 cm, what is its frequency? a) 100,000 cycles per second (hz) b) 1 × 10-3 cycles per second (hz) c) 10,000,000 cycles per second (hz) d) 1,000 cycles per second (hz)

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.
