Step-by-step explanation: well we have to use similarity. and that means setting up proportions so... 15/10 = BC/12 10BC=180, BC=18
9/18=DG/12 (we put 18 because it equals BC)
hope this helped!!
Answer:
19, 2
Step-by-step explanation:
let the 2 numbers be x and y with x > y , then
x + y = 21 → (1)
x - y = 17 → (2)
Add the 2 equations term by term to eliminate y , that is
2x = 38 ( divide both sides by 2 )
x = 19
substitute x = 19 into (1) for value of y
19 + y = 21 ( subtract 19 from both sides )
y = 2
The 2 numbers are 19 and 2
Answer:
y=1/2x-4
Step-by-step explanation:
Answer:
$0.65
Step-by-step explanation:
x=cost of washcloth
x+1.20=cost of towel
Now,
x+x+1.20=2.50
2x=1.30
x=0.65
So, cost of washcloth is $0.65
You multiply the area by 14 also
