1) $a= -1$ , 2) $n=-2$

3) $x=4$ , 4) $n=0$

5) $r=1$ , 6) $r=2$

7) $No\,\,solution$ , 8) $p=-12$

9) $m=2$ , 10) $a=-3$

11) $x=4$ 12) $n=-2$

Step-by-step explanation:

We need to solve each equation.

1) $6a+5a = -11$

Solving:

Adding like terms:

$11a = -11$

Divide both sides by 11

$a= -1$

2) $-6n-2n=16$

Solving:

Adding like terms:

$-8n=16$

Divide by -8

$n=-2$

3) $4x+6+3=17$

Solving:

Adding like terms:

$4x+9=17$

Subtract 9 on both sides:

$4x=17-9$

$4x=8$

Divide both sides by 4

$x=4$

4) $0=-5n-2n$

Solving:

$0=-7n$

Divide both side by -7

$n=0$

5) $6r-1+6r=11$

Solving:

12r-1=11

Adding 1 on both sides

$12r=12$

Divide both sides by 12

$r=1$

6) $r+11+8r=29$

Solving:

$9r+11=29\\9r=29-11\\9r=18\\r=2$

7) $-10=-14v+14v$

Solving

$-10=-14v+14v\\-10\neq 0\\No\,\,solution$

8) $-10p+9p=12$

Solving:

$-10p+9p=12\\-p=12\\p=-12$

9) $42=8m+13m$

Solving:

$42=8m+13m\\42=21m\\m=42/21\\m=2$

10) $a-2+3=-2$

Solving:

$a-2+3=-2\\a+1=-2\\a=-2-1\\a=-3$

11) $18=3(3x-6)$

Solving:

$18=3(3x-6)\\18=9x-18\\18+18=9x\\36=9x\\x=36/9\\x=4$

12) $30=-5(6n+6)$

Solving:

$30=-5(6n+6)\\30=-30n-30\\30+30=-30n\\60=-30n\\n=60/-30\\n=-2$

Which of the following is equivalent to 92 1/2 pounds in ounces

viva [34]

Well first, you have to see how many ounces are in 1 pound and there are 16 ounces in 1 pound.
So now, I am going to multiply 16×92 1/2 ( or 92.5 )
SO: 92.5
× 16
--------------
1480 ounces

WARRIOR [948]

Answer:

The range of values likely to contain the true value of the population parameter is between 44% and 52%.

Step-by-step explanation:

Confidence interval concepts:

A confidence interval has two bounds, a lower bound and an upper bound.

These bounds are dependent of the sample mean and of the margin of error.

The lower bound is the sample mean subtracted by the margin of error, while the upper bound is the margin of error added to the sample mean.

The confidence interval is likely to contain the true value of the population parameter.

In this question:

Sample mean: 48%

Margin of error: 4%

48 - 4 = 44%

48 + 4 = 52%

The range of values likely to contain the true value of the population parameter is between 44% and 52%.

An angle measures 62° more than the measure of its complementary angle. What is the

cestrela7 [59]

Answer:Let x be one of the angles.

Let (180-x) be the other angle we need.

x = (180-x) - 62

2x = 180-62

2x = 118

x = 118/2

x = 59�

180-59 = 121�

The two angles are 59� and 121�.

-4(5k-7)-2k=-2(9k+5)

Mice21 [21]

If you distribute -4 through (5k-7), it equals -20k + 28. Then put on the other -2k on that side of the equals sign and you should have -22k + 28 = -2(9k+5) Then you need to distribute -2 through (9k+5) which equals -18k - 10. You then should have -22k+28=-18k-10. Add 22k to both sides to cancel it out, then you should have 28=4k-10. Add 10 to both sides to get the 4k by itself, which will be 38=4k, then divide both sides by 4 to get k by itself. 38/4 = 19/2. k = 19/2
