1.a

2.c

3.b

4.784

5.part a: coefficient: 75 variable: d constant: 25

part b: 75d+8w+25=

75*5+8*48+25=

375+384+25=

759+25=

784

part c: the constant would change, because there is no variable attached to the number.

125/65=1.92 hours=115.2min=115min

65 miles per hour mean 65 miles per 60 minutes

65 miles per 60 minutes

5 miles per x minute

x = 5*60/65 = 300/65 = 4,6 min.

5 miles per 4,6 min.

125 miles per x min.

x = 125*4,6/5 = 25*4,6 = 115 min. = 1 h. 55 min.

hope this will help you

65 miles per hour meaning 65 miles in 60 minutes

65/60 = 1.083mile per minute

125/ 1.083 = 115.4 minutes to drive from san diego to malibu

check

115.4 x 1.083 = 124.97 (round up)

= 125

therefore it takes 115.4 minutes to drive from San Diego to Malibu

divide total miles by speed

125/65 = 1.923 hours

there are 60 minutes per hour

multiply 1.923*60 = 115.384 minutes

rounded off to nearest whole number = 115 minutes

If u doing 65 miles per hour then u will get there in 82 miles

It should take 115 minutes
