How can i show my work for 2x-4= -10+x

Answers

Let me help you with that :)

2x - 4 = - 10 + x (we transfer the x from the right side, and transfer the - 4 from the left side)

2x - x = - 10 + 4 (we calculate this)

x = -6

And that is the answer; x = - 6 :)

At the start of the day there are 78 boxes of DVDs in a warehouse. Each box has 116 DVDs. Then 19 of the boxes are shipped. Now how many DVDs are left in the warehouse?

Answers

Answer:

6844DVDs

Step-by-step explanation:

At the start of the day, there are 78boxes in the warehouse and each box contains 116DVDs, the total number of DVDs in the warehouse will be total number of DVDs per box × number of DVDs in each box;

No of DVDs in the warehouse = 78×116

= 9048DVDs

If 19boxes of DVD were shipped, the total number of DVDs shipped will be 19×116(remember there are 116DVDs in a box)

= 2204DVDs

To calculate the amount of DVDs left in the House, we will use the expression;

Total number of DVDs in the warehouse - total number of DVDs shipped

= 9048-2204

= 6844DVDs

2,204 dvds are left since 19 times 116 is 2,204

Solve for x please

Answers

Answer:

First Inequality: $x < -1.5$

Second Inequality: $x \geq 9.6$

Step-by-step explanation:

Step 1: Solve for x in the first inequality

$12x + 7 - 7 < -11 - 7$

$12x < -18$

$12x / 12 < -18 / 12$

$x < -1.5$

Answer: $x < -1.5$

Step 2: Solve for x in the second inequality

$5x - 8 + 8 \geq 40 + 8$

$5x \geq 48$

$5x / 5 \geq 48 / 5$

$x \geq 9.6$

Answer: $x \geq 9.6$
