Answer: Each hamburger cost $3.50
Step-by-step explanation:
He spent $13 in total and bought one hot dog for $2.50 and 3 hamburgers but we don't know the price of one hamburger so we could represent it by the equation,
2.50 + 3h = 13 Now solve for x
-2.50 2.50
3h = 10.50
h = 3.50
Check:
2.50 + 3(3.50) = 13
2.50 + 10.50 = 13
13= 13
Hey there!
For this problem, you'll first want to calculate how much the bill will be including the 20% tip. To convert a percentage to a decimal, take the decimal point to the left two numbers. Remember that 20 is the same thing as 20.0.
20% = 0.2
Next, multiply the amount by that decimal, then add the tip to the total bill.
<span>$52.35 * 0.2 = $10.47 (tip amount)
</span>$52.35 + $10.47 = $62.82 (total including tip)
Now, just divide that by four people to get your final answer.
$62.82 / 4 = $15.705
Because you can't have half of a cent, the problem probably just wants you to round up to $15.71, even though this will make the bill equal to $62.84.
Hope this helped you out! :-)
Answer:
x = 4, y = 12/5
Step-by-step explanation:
2x+5y = 20
6x-5y = 12
----------------- (+)
8x = 32 => x = 32/8 => x = 4
2·4+5y = 20 => 8+5y = 20 => 5y = 12 => y = 12/5
Answer:
5 is a prime number which means that it can only have 2 factors which is 1 and 5
Step-by-step explanation:
Hope this helps:)
Y=-4x-19 + y=4x+5 one hundred fourth place
