x - 6 = - 3 + 8

x = 5 + 6

x = 11

3w - 8w = 35

- 5w = 35

5w = - 35

w = - 35 : 5

w = - 7

3(3x - 3) = 10x

9x - 9 = 10x

- 9 = 10x - 9x

x = - 9

Answer:

1. x = 11,

2. w = -7,

3. x = -5

4. x = -5

5. x = -9

Step-by-step explanation:

1. x-6 = -3+8

x - 6 = 8 -3

x - 6 = 5

Adding 6 to both sides:

x - 6 + 6 = 5 + 6

x = 11

2. 3w - 8w = 35

3w - 8w = 35

-5w = 35

Divide both sides by -5

-5w/-5 = 35/-5

w = -7

3. - 4 x - 4 x = 44 - 4

- 4 x - 4 x = 44 - 4

-8x = 40

Divide both sides by -8

-8x/-8 = 40/-8

x = -5

4. 5 -8 = 3x +2 - 2x

Collecting like terms and rearranging equation

3x - 2x = 5 - 8 - 2

x = 5 - 10

x = -5

5. 3(3x - 3) = 10x

3(3x - 3) = 10x

Expanding and removing parenthesis

9x - 9 = 10x

Collecting like terms and rearranging equation

10x - 9x = -9

x = -9

What are the solutions of the quadratic equation (x + 3)(x +3) = 49? Ax = -2 and x = -16 Bx = 2 and x = -10 Cx = 4 and x = -10 D

Ivahew [28]

Answer:

4 and -10

Step-by-step explanation:

$\displaystyle (x + 3)(x +3) = 49 \\ x^2+3x+3x+9=49 \\ x^2 +6x+9=49 \\ x^2 + 6x + 9 - 49 = 0 \\x^2+6x-40=0 \\\\ \Delta=b^2-4ac \\ \Delta=6^2-4 \cdot 1 \cdot (-40) \\ \Delta=36+160 \\ \Delta=196 \\ \\ X_{1,2}=\frac{-b \pm \sqrt{\Delta} }{2a} \\ \\ X_1=\frac{-b+\sqrt{\Delta} }{2a} = \frac{-6+14}{2} = \frac{8}{2}=4 \\ \\ X_2=\frac{-b-\sqrt{\Delta} }{2a} = \frac{-6-14}{2}=\frac{-20}{2} = -10$

Daniella put $582 in the bank. Her brother put 3 times as much money in the bank. Her sister put 1/3 as much money in the bank.

mariarad [96]

Answer:

$2522; if her sister put in 1/3 of Daniella's original money.

But if you don't combine Daniella's original money it would be $2328

Step-by-step explanation:

582 x 3= 1746.

and 1/3 of 582= 194

582+1746+194=2522

Ann, Nan, and Jan snacked on a plate of fruit slices while doing their homework. Ann ate 1/5 of the fruit slices, Nan ate 2/5 of

Airida [17]

1/5 because 1/5+2/5+1/5=4/5 and out of a whole which would be 5/5, you would subtract 4/5 from 5/5
