$x$ - the number of the games he played

$\dfrac{x}{2}$ - the number of the games he won

$\dfrac{x}{3}$ - the number of the games he lost

$x=\dfrac{x}{2}+\dfrac{x}{3}+2\Big|\cdot6\\6x=3x+2x+12\\x=12$

Triangle ABC is congruent with triangle CDA Find the value of the pronumeral x.

brilliants [131]

Answer:

x = 25

Step-by-step explanation:

Since the triangles are congruent then corresponding angles are congruent.

That is ∠ D and ∠ B are corresponding angles and congruent, thus

4x - 20 = 2x + 30 ( subtract 2x from both sides )

2x - 20 = 30 ( add 20 to both sides )

2x = 50 ( divide both sides by 2 )

x = 25

Sherri currently has an account balance of $1,050.80. Her initial deposit on the account was $740 and it earned 3.5% simple inte

Yanka [14]

Answer:

Sherri has the account since twelve years ago

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Current balances of Sherri's account = $ 1,050.80

Initial deposit = $ 740

Interest rate = 3.5% simple interest = 0.035

2. How long has Sherri held the account?

Let's recall the formula of the simple interest:

FV = P * (1 + rt), where FV is the future value of the investment or initial deposit, P, the initial deposit, r, the interest rate and t, the number of periods.

Replacing with the values we have:

1.050.80 = 740 * (1 + 0.035t)

1,050.80 = 740 + 25.9t

1,050.80 - 740 = 25.9t

310.80 = 25.9t

t = 310.80/25.9

t = 12

Sherri has the account since twelve years ago
