36
Answer:
26
Step-by-step explanation:
Let the peter's number be represented x
Given that
1. if you subtract 19 from my number
writing it mathematically it will be x -19
2. multiply the difference by -3
it can be written as
since difference is x-19
multiplied the difference with -3
-3(x-19)
3. the result is -21
-3(x-19) = -21
dividing both side by -3
-3(x-19)/-3 = -21/-3
x-19 = 7
adding 19 both sides
x-19 + 19 = 7 + 19
x = 26
Thus, peter's number is 26.
Answer:
170 people I believe
Step-by-step explanation:
93 + 47 = 140
140 + 25/2 = 140 + 13 = 170
5. 1:175, if 2ft= 350 ft in life 1ft feet would probably be 175. (Cross multiplication)
6.a)100miles, 1 inch= 20mile so 5 inches multiplied by 20 miles gives you 100miles
b) 10 inches from Appleton. 1inch:20miles (cross multiply to get 10inches)
x :200miles
c)25000 miles will reach the equator so 50000 miles will go around the world! So, if 1inch:20miles,(50000/20=2500inches) And if 12inches:1ft, 2500inches * 1ft/12 inches to get 208.33.
7.a) 1inch:2.5miles(5inches*2.5miles/1) 5inches would be 12.5miles.
b)1inch:2.5miles, 41miles?. (1inch*41miles/2.5miles=x) x=16.4, so 41miles=16.4inches
c)No. Because they have different scales.
