The equations classified according to the number of solutions are given as follows:

  • No solution: -3(3q + 4) = -6q + 12
  • One solution: -2(3n - 4) = -6n - 4
  • Infinitely many solutions: 8z - 4 = 8z - 4

<h3>How many solutions does the equation 4(2z - 1) = 8z - 4 has?</h3>

We solve the equation, hence:

4(2z - 1) = 8z - 4

8z - 4 = 8z - 4

Equivalent, hence they have infinitely many solutions.

<h3>How many solutions does the equation -2(3n - 4) = -6n - 4 has?</h3>

-2(3n - 4) = -6n - 4

-6n + 8 = -6n - 4

0 = -12, which is false, hence it has no solutions.

<h3>How many solutions does the equation -3(3q + 4) = -6q - 12 has?</h3>

-3(3q + 4) = -6q + 12

-9q - 12 = -6q + 12

3q = -24

q = -8.

One solution.

at the mall, myla bought a shirt for $25.36, a hat for $5.09 and a belt for $11.45. how much did she spend altogether?
malfutka [58]

The summation of the money Myla spend altogether is $41.9

As in the given problem  we can see Myla bought

a shirt for $25.36 and

a hat for  $5.09  and

a belt for $11.45.

Hence we need to know the cummulative price she spend altogether.

To get the total price we should add the price of shirt hat and belt.

Summing all the prices we get

$25.36+$5.09+$11.45=$41.9

As all the quantities are given in one currency thus we can add them by simple addition formula.

Thus she spend $41.9 altogether at the mall.

Solve for w. 5w + 9z = 2z + 3w w = w equals negative StartFraction 7 Over 2 EndFraction z.Z w = w equals negative StartFraction
TEA [102]

Answer:

w = -7z/2

Step-by-step explanation:

We need to solve for w in terms of z.

The equation given is:

5w + 9z = 2z + 3w

Collect like terms:

5w - 3w = 2z - 9z

2w = -7z

w = -7z/2
