Answer:
The scale factor is 4.5
Step-by-step explanation:
Scale factor from ∆RST to ∆XYZ = side length of ∆XYZ / corresponding side length of ∆RST
Thus:
XY corresponds to RS
XY = 45
RS = 10
Therefore:
Scale factor = 45/10 = 4.5
Scale factor from ∆RST to ∆XYZ = 4.5
 
        
             
        
        
        
Answer:
x > -3_2/3
Step-by-step explanation:
(3x+6)-2 < 10
Distribute  
-6x-12 < 10
     +12   +12
     -6x < 22
-6x/-6 < 22/-6
When you divide by a negative number you flip the inequality 
x > 22/-6
Simplify 
x > -3_2/3
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Given

The area of the garden
First, we calculate the length of the other side using:

This gives:

Divide both sides by 2

Make Side 2 the subject

So, the area of the garden is:

Answer: 46
Step-by-step explanation:
percentage scored = 92
number of correct question = x
total number of questions = 50
The formula for calculating the percentage scored 
= number of correct question / total number of questions x 100
That is 
92 =  x
 x 

cross multiplying :
 x
 x 

dividing through by 100 , we have 

Therefore, she got 46 questions right
