Easy,

23y-(7x-2y)+x

<span>There is an imaginary</span> 1 in front of the parentheses, making it,

23y-1(7x-2y)+x

Now, distribute the 1.

-1*7x= -7x
and
-1*-2y= 2y

Leaving your problem looking like...

23y-7x+2y+x

Combine your apples and oranges.....

25y-6x

Thus, your answer.

suter [353]

Answer:Amount = 10,002.21



Step-by-step explanation:4 x 5 = 20 times


2.-

Principal = 5,000

Interest rate per yr = 3%

Compounded times per yr = 4

Time in years = 5


The formula is amt = p*(1 + r/n) ^ (n*t),

thus

Amount = 5,805.92


3.-

If Time in years = 23.2

then

Amount = 10,002.56


4.-

Principal = 5,000.00

Interest rate per yr = 5.82%

Compounded times per yr = 4

Time in years = 12

In isosceles triangle ABC, AC=BC=20, the measure of angle A=68, and CD is the altitude to side AB. What is CD to the nearest 10t
antiseptic1488 [7]

Answer:

Step-by-step explanation:

Comment

The way the diagram looks when it is drawn is that you are going to need the sine function to solve for the side opposite which is CD.

Formula

Sin(A) = Sin(68 = opposite / hypotenuse     Substitute values.

Solution

sin(68) = altitude (side opposite) / 20       multiply both sides by 20

20*sin(68) = 20* altitude / 20                     substitute for sin(68)

20* 0.9272 = altitude

altitude = 18.5

Answer: 18.5 to the nearest tenth
