∆ABC is an isosceles triangle in which angles B and C are congruent.

Brut [27]

Since B and C are congruent, that means that 4x+10=x+34. Using the addition property of equality, I challenge you to solve for x! After you do that, you can note that all the angles in a triangle add up to 180, so 4x+10+x+34+angleA=180. When you find x, you can substitute that in.

If you need help with the addition property of equality for variables, here's an example - 5x+23=4x+3. Subtracting 3 from both sides, we get 5x+20=4x. Next, we can subtract 5x from both sides to get -x=20 and divide both sides by -1 to get x=-20.

Good luck, and feel free to ask with any questions!

What is -27/25x-9/5 pls help me

morpeh [17]

$-\dfrac{27}{25}x-\dfrac{9}{5}=-\dfrac{27}{25}x-\dfrac{9\cdot5}{5\cdot5}=-\dfrac{27}{25}x-\dfrac{45}{25}=\dfrac{-27-45}{25}\\\\=-\dfrac{72}{25}=\boxed{-2\dfrac{22}{25}}$

6. Using Table 11-2 from your text, calculate the present value (principal) and the compound interest given: Compound Amount = $

storchak [24]

Answer:

The Principal is $877.19 And Compound Interest is $372.81

Step-by-step explanation:

Given as :

Amount after investment = $1250

The time period of investment = 6 years

The nominal rate = 6% compounded semiannually

Let the principal = P

From compounded method

Amount = Principal × $(1 + \frac{Rate}{2\times 100})^{2\times Time}$

Or, $1250 = P × $(1 + \frac{6}{2\times 100})^{2\times 6}$

Or, $1250 = P × $(1.03)^{12}$

Or, $1250 = P × 1.425

∴ P = $\frac{1250}{1.425}$

I.e P = $877.19

So , Principal = $877.19

Now, Compound Interest = Amount - Principal

= $1250 - $877.19

Or, CI = $372.81

Hence The Principal is $877.19 And Compound Interest is $372.81 Answer
