Please help <br><br> -2/3 (x-3) - x = 8
GalinKa [24]

Answer:

-18/5 or - 3 3/5.

Step-by-step explanation:

-2/3 (x-3) - x = 8

-2/3x + 2 - x = 8

-2/3x - 3/3x  = 8 - 2

-5/3 x = 6

x =   6 * -3/5

x = -18/5

A. 39<br> B. 55<br> C. 66<br> D. 82
kherson [118]

Answer:

D) 82 units

Step-by-step explanation:

ΔBCD ≅ ΔEFG

In congruent triangles, corresponding parts are congruent

BD  = EG

4x - 9 = 2x + 15

4x - 9 -2x = 15

2x - 9 = 15

    2x = 15 +9

    2x = 24

      x = 24/2

      x = 12

EG =  2x + 15 = 2*12 + 15

     = 24 + 15

EG = 39 units

FE = CB =   17 units

Perimeter of ΔEFG = FE + EG + GF

                               = 17 + 39 + 26

                               = 82 units

Put the equation y = x^2 + 26 x + 160 into the form y = ( x − h )^2 + k :
SVEN [57.7K]

y = (x^2 + 26x)     +160  complete the square

y = (x^2 + 26x  )     + 160    

       Split our the constant and  use the (b/2)^2

y = (x^2 + 26x + (26/2)^2 )     + 160 - (26/2)^2

       since I am adding the new value I must subtract it from the end to keep        the balance

y = (x^2 + 26x + 169)     + 160 - 169

       Now factor parenthesis and combine like terms

y = (x+13)^2  -9  its in the vertex form

Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 1 more than 3 times the number o
Margaret [11]

Answer:

Mark has 13 marbles

Don has 40 marbles

Step-by-step explanation:

Let the number of Mark's Marbles = M

Let the number of Don's Marble = D

D = 1 + 3M - - - - (1)  (Don has 1 more than 3 times the number of marbles Mark has)

D + M = 53 - - - - - (2) (total number of marbles is 53)

puttin the value of D from equation (1) into equation (2)

(1 + 3M) + M = 53

1 + 3M + M = 53

1 + 4M = 53

4M = 53 - 1 = 52

4M = 52

M = 52 ÷ 4

M = 13

finding D by putting the value of M (M = 13) into equation 1

D = 1 + 3M - - - - (1)

D = 1 + 3 (13)

D = 1 + 39

D = 40

∴ Mark has 13 marbles

Don has 40 marbles
