Equation 1) 8x + 6y = 48
Equation 2) 2x - 3y = -6

Multiply all of equation 2 by 2.

2) 2(2x - 3y = -6)

Simplify.

2) 4x - 6y = -12
1) 8x + 6y = 48

Add equation together.

12x = 36

Divide both sides by 12.

x = 3

Plug in 3 for x in the first equation.

8x + 6y = 48

8(3) + 6y = 48

Simplify.

24 + 6y = 48

Subtract 24 from both sides.

6y = 48 - 24

Simplify.

6y = 24

Divide both sides by 6.

y = 24/6

y = 4

So, x = 3, y = 4

The first five terms of a pattern are shown.

Andrej [43]

Answer:

Step-by-step explanation:

There is a common ratio between consecutive term in the sequence, that is

$\frac{3}{10}$ ÷ $\frac{3}{100}$ = 3 ÷ $\frac{3}{10}$ = 30 ÷ 3 = 300 ÷ 30 = 10

This indicates the sequence is geometric with n th term

$a_{n}$ = a $(r)^{n-1}$

where a is the first term and r the common ratio

Here a = $\frac{3}{100}$ and r = 10 , thus

$a_{n}$ = $\frac{3}{100}$ $(10)^{n-1}$

= $\frac{3}{10^{2} }$ × $10^{n-1}$

= 3 × $10^{-2}$ × $10^{n-1}$

= 3 × $10^{n-3}$

Thus

$a_{n}$ = 3 $(10)^{n-3}$ → C

What is 0.472 rounded to the nearest tenth? (2 points)<br><br>

MA_775_DIABLO [31]

To round 0.472 to the nearest tenth consider the hundredths' value of 0.472, which is 7 and equal or more than 5. Therefore, the tenths value of 0.472 increases by 1 to 5.

So, the answer would be 0.5.
