Please answer full question below thank you
Yuliya22 [10]

Explanation:

Angles 1 & 2 have to equal 180. So, if ∠1 is equal to 140, ∠2 is equal to 40 because 140 + 40 = 180.

So far... we know that:

  • ∠2 = 40
  • ∠9 = 80

Angles 2, 9, and 11 make a triangle, a triangles "magic number" is also 180. To get 180, you must add up all of the angles. Well... we don't know ∠11 so to find it, you subtract 40 & 80 from 180. 180 - 80 - 40 = 60.

Answer:

∠2 = 40

∠11 = 60

John is 6 years older than Keisha. Together, their ages equal four times Keisha's age. How old is each? (Note: There must be an
borishaifa [10]
<span>k= Keisha  
k + 6= John</span> <span>         
k + k + 6 =  4k</span> <span>  
2k + 6 ( - 2k) =  4k ( - 2k)</span> <span>              
6 = 2k</span> <span>           
3 = k    
(Keisha= 3 years old)</span> <span>         
k + 6 = 9    
(John = 9 years old)
</span>
3 + 3 + 6 = 4 (3) <span>         
12 = 12

</span><span>So we made the pawn represent Keisha’s age.  Then we knew that John is 6 years older than Keisha so we represented his age with a pawn plus 6. This went on 1 side of the equation because it said that together they equal 4 times Keisha’s age. So on the other side of the equation we put 4 pawns because we are using each pawn as Keisha’s age.  Then we subtracted the pawns from each side to keep the equation balanced.  So we had that 2 pawns equal 6, which means that each pawn equals 3 so Keisha is 3 years old.  Since John is 6 years older than Keisha, he must be 9 years old.  We checked our work and substituted 6 in for each pawn and found that 12 equals 12, so our equation is balanced.

Crazy boy [7]

10 km

Step-by-step explanation:

If 4 cm represents 8 kilometers then 1 cm represents;

8 / 4

= 2

1 cm : 2 km

How, then, about 5 cm – the distance between Sophie's home and school?

5 cm : ? km

A cross multiplication;

1 cm : 2 km

5 cm : x km

(5 * 2) = 1 x

x = 10/1

x = 10
