Answer:
c = 6
Step-by-step explanation:
Step 1: Write equation
2(5c + 2) - 2c = 3(2c + 3) + 7
Step 2: Solve for <em>c</em>
- Distribute: 10c + 4 - 2c = 6c + 9 + 7
- Combine like terms: 8c + 4 = 6c + 16
- Subtract 6c on both sides: 2c + 4 = 16
- Subtract 4 on both sides: 2c = 12
- Divide both sides by 2: c = 6
Question:
The cost of 12 kg sugar is $240 what will be the cost of 3 kg sugar.
Given:
- Cost of 12 kg sugar = $240
To find?
Answer :
<u>To find </u><u>c</u><u>o</u><u>s</u><u>t</u><u> </u><u>of</u><u> </u><u>3kg sugar first we have to find cost of 1 kg sugar</u><u>.</u>
- Cost of 1 kg sugar = Cost of total no. of sugar ÷Total sugar
- Cost of 1 kg sugar = $240/12
- Cost of 1 kg sugar = $20
<u>Now Let's find cost of 3 kg sugar</u>
Cost of 3kg sugar = total no of sugar ×Cost of 1 kg sugar
Cost of 3kg sugar = 3×$20
Cost of 3kg sugar = $60
Answer:
$180
Step-by-step explanation:
To solve, we can set up a proportion and solve.
You earn $45 for 7.5 hours of work, and you earn $ x for 30 hours of work
45/7.5=x/30
Cross multiply
45*30=7.5*x
1350=7.5x
To solve for x, we need to get x by itself. It is being multiplied by 7.5. To undo this, divide both sides by 7.5
1350/7.5=7.5x/7.5
180=x
So, for 30 hours of work, you would earn $180
You need to divide the minutes by hours
So now f one in inches is 25.4 then you divide 203.2 / 25.4 = 8
