Well if you learned about pots and coins it should help.
first start by making the equation smaller.
16x+9=9y-2x
+2 +2
18x+9=9y
x=9y-9/18
take out the 9 by both sides
x=y-1/2

Remmber you can do ANYTHING to an equation as long as you do it to BOTH SIDES

solve for y

16x+9=9y-2x
add 2x to both sides
18x+9=9y
diide both sides by 9
2x+1=y
y=2x+1

Find A and C,Laws of sines and cosines

stealth61 [152]

Answer:

$AC=15.9976$

Step-by-step explanation:

Law of Sines: $\frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}$

Step 1: Define

a = 8 ft

A = 30°

b = ?

B = 89°

Step 2: Substitute and Evaluate

$\frac{sin(30)}{8} =\frac{sin(89)}{b}$

$bsin(30)=8sin(89)$

$b=\frac{8sin(89)}{sin(30)}$

$b=16cos(1)$

$b=15.9976$

$AC=15.9976$

the arithmetic sequence ai is defined by the formula: a1 = -53 ai = ai-1 + 6 find the sum of the first 880 terms in the sequence

maxonik [38]

Answer:

The sum of the first 880 terms in the sequence is 2,273,920.

Step-by-step explanation:

Arithmetic sequence:

The difference between consecutive terms is always the same, called common difference, and the nth term is given by:

$a_{n} = a_0 + (n-1)d$

In which d is the common difference.

Sum of the first n terms:

The sum of the first n terms of an arithmetic sequence is given by:

$S_{n} = \frac{n(a_1+a_n)}{2}$

ai = ai-1 + 6

This means that $d = 6$

In this question:

Sum of the first 800 terms, so $n = 800$

First term is -53, so $a_1 = -53$

The 880th term is:

$a_{880} = -53 + (880-1)*6 = 5221$

Sum

$S_{n} = \frac{880(-53+5221)}{2} = 440(-53+5221) = 2273920$

The sum of the first 880 terms in the sequence is 2,273,920.
