Step 1: distribute.
Multiply 2 time x and 2 times 2 that would give you 2x+4+8=6.

step 2: combine like terms.
Add 4 and 8 and it would give you 2x+12=6.

step 3: substract 12 in both sides.
6-12= -6 it would end up being (2x= -6).

step 4: divide 2 in both sides.
2 divided by -6 gives you -3.

Answer:
x= -3

A low-strength children’s/adult chewable aspirin tablet contains 81 mg of aspirin per tablet. How many tablets may be prepared f
Svetlanka [38]

Answer:

12,345 tablets may be prepared from 1 kg of aspirin.

Step-by-step explanation:

The problem states that low-strength children’s/adult chewable aspirin tablets contains 81 mg of aspirin per tablet. And asks how many tablets may be prepared from 1 kg of aspirin.

Since the problem measures the weight of a tablet in kg, the first step is the conversion of 81mg to kg.

Each kg has 1,000,000mg. So

1kg - 1,000,000mg

xkg - 81mg.

1,000,000x = 81

x = \frac{81}{1,000,000}

x = 0.000081kg

Each tablet generally contains 0.000081kg of aspirin. How many such tablets may be prepared from 1 kg of aspirin?

1 tablet - 0.000081kg

x tablets - 1kg

0.000081x = 1

x = \frac{1}{0.000081}

x = 12,345 tablets

12,345 tablets may be prepared from 1 kg of aspirin.

Lincoln Middle School plans to collect more than 2000 cans of food in a food drive. So far, 668 cans have been collected. Write
Schach [20]
Let x be the unknown number.

<span>7x + 668 </span><<span> 2000</span>     => 7x plus 668 is less than 2000

where: 
7x => x represents the number of cans to be collected in 7 days
668 is the number of cans already collected. 
2000 is the target number of cans.

7x  +  668    <    2000
        - 668           -668
7x                <   1332
÷7                        ÷7
x                  <    190.30
or
x < 190

To check:

7x + 668 < 2000
7(190) + 668 < 2000
1330 + 668 < 2000
1998 < 2000
