Answer:
<u>There are 97 nickels in the jar</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Number of coins = 205
Number of nickels = x
Number of quarters = 205 - x
Value of the 205 coins = $ 31.85
2. If both of these statements are true, how many nickels are in the jar?
Let's solve for x, this way:
0.05x + 0.25 (205 - x) = 31.85
0.05x + 51.25 - 0.25x = 31.85
-0.2x = 31.85 - 51.25
-0.2x = - 19.4
x = -19.4/-0.2
x = 97 ⇒ 205 - x = 108
<u>There are 97 nickels and 108 quarters in the jar</u>
Answer:
They given expresión is Pd y no mi al
The two lines are horizontal, so the two triangles in the diagram are similar because their internal angles are the same. By the proportionality of similar triangles, x/(x+5)=(x-2)/(x+1). Solve the equation, x^2+x=x^2+3x-10, x=3x-10, x=5.
X=7
add 3 to both sides.
hope this helps!
