20x2= 40 just like 20+20=40
Translations of geometric figures in the coordinate plane can be determined by translating the x- and y-coordinates of points. Horizontal and vertical translations are the easiest. ... Solution: A horizontal translation just changes the x-coordinates of all points, so the rule is (x, y) à (x + 3, y).

Hello your question is incomplete attached Below is the missing histogram
answer: 10 map squares
Step-by-step explanation:
There are 10 map squares that did survive more than 29 pant species because from the given diagram we can see that the plant species above 29 are spotted in 4 map squares ( i.e. from spot 30 to 39 ) and 6 map squares ( i.e. from 30 to 49 )
hence the total number of map squares = 4 + 6 = 10 map squares
This is a proportion problem. Start by doing:
2/3 = x/52.20
Multiply both sides by 52.20
X= 34.8 this is how much the son paid
Now add 34.8 + 52.20
Answer is 87
