The answer is 74. The parenthesis is another way of telling you to multiply.

The first step to solving this expression is to remove the first set of parenthesis and then remove the parenthesis from all positive numbers.
-9 - 9 × (-3) - 8 × (-7)
Multiply the numbers -9 and (-3) together.
-9 + 27 - 8 × (-7)
Multiply the numbers -8 and (-7) together.
-9 + 27 + 56
Lastly,, use addition and subtraction rules to calculate the expression and find your final answer.
74.
This means that the final answer to your expression is 74.

ANSWER

The second term is 7.

EXPLANATION

The given sequence has it's first term to be:

t_1 = 3

The recursive definition is :

t_{n+1}=2t_n+n

To find the second term , we substitute n=1,

to obtain,

t_{1+1}=2t_1+1

This implies that:

t_{2}=2t_1+1

t_{2}=2(3)+1

Simplify:

t_{2}=6+1

t_{2} = 7

someone help me please I don't want to do this by myself because I don't fully understand I need to finish this tonight
Alecsey [184]

Answer:

Step-by-step explanation:

so to make infinite many solutions.. the lines have to be the same line... so the 1st equation would just be a multiple of the 2nd.... like  2x... like that..or even 1x.. counts.. so the exact same equation

1 => C

2 => A

3 => D

4 => E

5 =>B

2nd picture: No solution means the lines are parallel but not on top of  as the last 5 equations were

6=> 5/4x -10  then a parallel line has the same slope but a different off set

so => 5/4x-5

7=> -8x + 12

so => -8x +1

8 => 4x + y = 7

y=-4x + 7

=> -4x +2

9=> sum of A+B=8   can A+B also be 10    NO!!!  >:/ grrr   if the 2nd set of numbers were C+D =10 then yes.. of course  

10=> sum of A + B =8 can A-B also be 8 ?   no

Joni’s hair is 13 inches long and grows at an average rate of ⅔ in per month. Her friend Kate’s hair is 16 inches long and grows
Gelneren [198K]
<h3>18 months will pass before the two friends have the same hair length</h3>

<em><u>Solution:</u></em>

Let "x" be the number of months

Joni’s hair is 13 inches long and grows at an average rate of ⅔ in per month

Equation : 13 + \frac{2}{3}x ------- eqn\ 1

Her friend Kate’s hair is 16 inches long and grows at an average rate of ½ in per month

Equation: 16 + \frac{1}{2}x ----- eqn\ 2

<em><u>For two friends to have the same hair length, eqn 1 must be equal to eqn 2</u></em>

13 + \frac{2x}{3} = 16 + \frac{x}{2}\\\\\frac{2x}{3} - \frac{x}{2} = 16 - 13\\\\\frac{4x}{6} - \frac{3x}{6} = 3\\\\x = 18

Thus 18 months will pass before the two friends have the same hair length
