Solve the equation 3x + 4 = 5x - 8​
CaHeK987 [17]

Answer:

x = 6

Step-by-step explanation:

3x + 4 = 5x - 8

==> add 8 to both sides

in doing so we get 3x + 4 + 8 = 5x - 8 + 8

the -8 and the +8 cancels out and 4 + 8 = 12

we are left with 3x + 12 = 5x

==> subtract 3x from both sides

in doing so we get 3x - 3x + 12 = 5x - 3x

the 3x and -3x cancel out and 5x - 3x = 2x

we are left with 12 = 2x

==> divide both sides by 2

in doing so we get 12/2 which equals 6 and 2x/2x which leaves us with

6 = x

The local hardware store wants to increase their inventory. last year 15 electric screwdrivers cost them $300. at the same cost,
VMariaS [17]

Answer:

Cost of 45 screwdrivers will be = $900

Step-by-step explanation:

Last year 15 electric screwdrivers cost to the local hardware store = $300

So per screwdriver cost = \frac{\text{Total cost}}{\text{Total number of screw drivers}}

= \frac{300}{15}

= $20

Now we have to calculate the cost of 45 screw drivers.

Since cost of 1 screwdriver = $20

So cost of 45 screwdrivers = 20×45 = $900
