Answer:
Step-by-step explanation:
The formula for simple interest is
I = Prt
where I is the interest earned, P is the initial deposit, r is the rate in decimal form, and t is the time in years. For us,
I = 125(.03)(3) which gives us an interest amount of
I = 11.25
To find out how much money she has total after that interest builds up, we add that interest amount to the initial investement amount to get
125 + 11.25 = 136.25
14=6+2x
subtract six from both sides
8=2x
divide both sides by 2
4=x

Answer:
84 feet
Step-by-step explanation:
Let the feet be A
1 foot = 0.33 yard
A feet = 28 yards
Cross multiply
A x 0.33 = 28 x 1
Divide both sides by 0.33
A x 0.33/0.33 = 28/0.33
A = 84.84
A = 84 feet
Therefore, there are 84 feet in 28 yards
Answer:
x = ±1
Step-by-step explanation:
Step 1: Define variables
f(x) = x² + 1
f(x) = 2
Step 2: Substitute
2 = x² + 1
Step 3: Solve for <em>x</em>
0 = x² - 1
0 = (x - 1)(x + 1)
x - 1 = 0
x = 1
x + 1 = 0
x = -1
∴ x = ±1
