Answer:

26.25 km

Step-by-step explanation:

Step up a portion.  Here, 4 cm is to 7 cm as 15km is to x km

4/7 = 15/x

Now solve for x by cross multiplying

4x = 105

  x = 105/4    (divide by 4 on both sides)

  x = 26.25 km    (simplify)

What is the value of B - A as a fraction?
umka21 [38]
Answer:
A = 1/4
B = 3/4

the middle should be 1/2 because the middle between 0 and 1 is 1/2
A and B are both in the middle of the sides
therefore A would be closer to 0 so 1/4
and B would be closer to 1 so 3/4

The students at Midtown Middle school sold flowers as a fundraiser in September and October. In October, they charged $1.50 for
Phoenix [80]
Let the price of flowers in September be x, then (100 + 20)/100 * x = $1.50
120/100 * x = $1.50
1.2x = $1.50
x = $1.50/1.2 = $1.25
The price of flowers in September is $1.25

Total money realised in September = $1.25 x 900 = $1,125
40% earned = 0.4 x $1,125 = $450

Total money realised in October = $1.50 x 700 = $1,050
40% earned = 0.4 x $1,050 = $420

The class earned more money in September and they earned $30 more than in October.
