Step-by-step explanation:
$5 US dollar = L123 Honduran Lempiras
L2300Honduran Lempiras = x ( Let $ be x) 
By using chain rule, we get
5×2300 = 123×x
or, 11500 = 123x
or, x = 11500÷123
hence, x = 93.49593496
 
        
             
        
        
        
Answer
a. The backpack is $4.50
b. The sweatshirt is $2.70
Step-by-step explanation:
a. 30 x 0.15 = 4.50 (The 0.15 is from the price you are actually paying for the item. Because the item is 85% off, you are paying for 15% of the usual price. 15% as a decimal is 0.15 so you multiply that to the original price to find the amount u will pay.)
b. 18 x 0.15 = 2.70   
 
        
             
        
        
        
Answer:
x=5,y=3
Step-by-step explanation:
 
the first step is to decide whether you want to substitute y and find x, or substitute x and find y.
 (it doesn't matter which way you will choose.If you do the math correctly you will get the correct answer,one way or another).
for example, let's substitute y into the first equation:
x=17-4*(x-2)
so now,we will organize the equation:
x+4x=17+8
5x=25/(÷5)
x=5
now we will substitute x with 5 in the second equation(or the first one,it doesn't matter)in order to find y:
y=5-2
y=3
 
        
             
        
        
        
To answer this i need a little more info but it's probably going to be 30 miles.
