Find legit BD<br><br> I need help for my assignment

never [62]

Answer:

BD = 4

Step-by-step explanation:

∆BAD is congruent to ∆CAD based on the AAS Congruence Theorem.

Therefore:

BD = CD

3x + 1 = 5x - 1 (substitution)

Collect like terms

3x - 5x = -1 - 1

-2x = -2

Divide both sides by -2

x = -2/-2

x = 1

✔️BD = 3x + 1

Plug in the value of x

BD = 3(1) + 1

BD = 3 + 1

BD = 4

Jacob invested $300 in a savings account and earned $81 in simple interest at the end of 9 years. what was the interest rate

Brilliant_brown [7]

Answer:

Step-by-step explanation:

We use the simple interest equation of A=P(1+rt).

A-the total amount with interest earned

P-the initial amount or principal

r-rate

t-time in years

We substitute the values P=300, A=381, and t=9. We then solve for r.

$381=300(1+9r)$

We divide both sides by 300.

$\frac{381}{300}=\frac{300(1+9r)}{300}$

Simplify.

$1.27=1+9r$

We subtract 1 from both sides.

$1.27-1=1-1+9r$

Simplify.

$0.27=9r$

We divide by 9.

$\frac{0.27}{9}=\frac{9r}{9}$

r=0.03

We need to convert the decimal to a percentage by multiplying by 100.

The interest rate is 3%.
