Answer:
171.2
Step-by-step explanation:
7% x 160 = 11.2
11.2 + 160 = 171.2
 
        
             
        
        
        
We need 6.5% to a decimal so..
6.5% /100 = 0.065
$21.30 X 0.065 = 1.3845 tax on the shirt
 
So.. we add the price of the shirt, and the amount of tax on the shirt
$21.30 + 1.3845 = $22.6845
Answer = $22.68
        
             
        
        
        
1- Solution using graphs:Take a look at the attached images. 
The red graph represents the first given function while the blue graph represents the second given function.
We can note that the two graphs are the same line (they overlap). 
This means that any chosen point on one of them will satisfy the other.
This means that there are infinite number of solutions to these two equations.
2- Solution using substitution:The first given equation is:
y = -5x + 3 ...........> equation I
The second given equation is:
2y + 10x = 6 ...........> equation II
Substitute with I in II and solve as follows:
2(-5x+3) + 10x = 6
-10x + 6 + 10x = 6
0 = 0
This means that there are infinitely many solutions to the given system of equations.
Hope this helps :)
 
        
             
        
        
        
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The decimal would be .70 because there's 70 squares that are shaded.
 
        
             
        
        
        
[(8 - 2 * 29)]/3
Let's solve inside the brackets first.
According to PEMDAS, multiplication gets solved before subtraction so multiply 2 * 29 in the parentheses.
[(8 - 58)]/3
Subtract 58 from 8 in the parentheses.
(-50)/3
Divide -50 by 3.
-16.667 or -16 2/3 is your answer.
