Answer: x = -7/2
Step-by-step explanation:
10x+ 30 = 20 +8x+ 3
10x+ 30=23+8x
10x-8x = 23-30
2x=-7
( a helpful app to help with these type of problems is photomath)
( 2x +5)^2 =4
2x+5=2
2x=-3
X=-3/2
1/36 because there are 6 sides and the you are trying to figure out what the probiblity of rolling 1 out of 6 is
In the given problem there are several known and important facts to take note of. Firstly the restaurant bill without tax and tips is $28.35. Then the tax of 6.25% needs to be added with the bill. Also a tip of 20% on the original bill needs to be added to find the total cost.
Then tax on the restaurant bill = (6.25/100) * 28.35
= 1.77
So the tax on the restaurant bill is $1.77
Amount of tips given = 28.35 * (20/100)
= 5.67
Amount of tips paid is $5.67
Total cost paid in the restaurant = ( 28.35 + 1.77 + 5.67) dollars
= 35.79 dollars
It would take 110 seconds or a minute and 40 seconds. 400 divided by 50 = 4...... 27.5 multiplied by 4 equals 110; therefore, the answer is mike would swim 400 meters in 110 seconds.
