-79 = 7w + 3(4w – 1)​
vladimir1956 [14]

Hello! The answer to your question would be as followed:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    -79-(7*w+3*(4*w-1)=0

 -79 -  (7w +  3 • (4w - 1))  = 0

Pulling out like terms :

  Pull out like factors :

  -19w - 76  =   -19 • (w + 4)

 -19 • (w + 4)  = 0

Equations which are never true :

      Solve :    -19   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

     Solve  :    w+4 = 0

Subtract  4  from both sides of the equation :

                     w = -4

                  w = -4

elijah's credit card statement showed these items: Last Balance Payments Finance Rate New Charges $152.58 $45.00 1.5% $213.40 Wh
elena55 [62]

Answer:

Option A,$320.98  is correct

Step-by-step explanation:

The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.

last balance as shown by the statement was $152.58

new charges were $213.40

payment made by Elijah was  $45

new balance=$152.58+$213.40-$45=$320.98

The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.

Find the quotient of 2,300 and (0.4 · 10^-8). In your final answer, include all of your calculations.
Alex777 [14]

Answer:

5.75x10^11

Step-by-step explanation:

quotient of 2,300 and (0.4x10^-8) is

2,300 ÷ (0.4x10^-8)

2300 = 2.3x10^3

We now have

2.3x10^3 / 0.4x10^-8

= (2.3/0.4) x ( 10^(3 - (-8))

= 5.75 x (10^(3+8))

= 5.75 x (10^11)

= 5.75x10^11

Please mark brainliest if helpful. Thanks
