Answer:
because MATH is a rhombus
=> MA = MH = HT = AT
=>  y + 10 = 5y - 6
⇔ 4y = 16
⇔ y = 4
with y = 4 => MH = 4 + 10 = 14
but MH = MA
=> MA = 14

Answer:
Saving=£450
Spent=£200
Step-by-step explanation:
Ratio of saving to spending is 9:4
She inherits £650
So to determine her saving
It will be
9+4=13
Since her saving is 9
So, 9/13 × 650
 5850/13 
 =450
So her saving is£450
To determine what she spent
4/13 × 650
2600/13
200
Saving=£450
Spent=£200
 
        
                    
             
        
        
        
Answer:
<h3>              

 </h3>
Step-by-step explanation:
3, 9, 15, 21,  ...
9-3 = 6;   15-9 = 6;   21-15 = 6   ⇒  d = 6
first term:  a = 3
difference:  d = 6
so the formula:
                           
                         
and:
