We can do like we did before, distribute the denominator,
It would be 190 minutes, and around 48 seconds.
Answer:
2(7) - 1/4 = 4 + 1/3x
x = 117/4
Step-by-step explanation:
solving an equation with one missing variable
step 1: multiply 2 * 7
ex: 14 - 1/4 = 4 + 1/3x
step 2: subtract 14 from 1/4
ex: 55/4 = 4 + 1/3x
step 3: subtract 4 from both sides of the equation
55/4 - 4 = 4 + 1/3x - 4 (39/4 = 1/3x)
step 4: divide both sides of the equation by 1/3
ex: 39/4 / 1/3 = 1/3x / 1/3 (x = 117/4 or x = 29 1/4)
step 5: to check your answer add the answer you got from the last equation which was 117/4 or 29 1/4 and input it into the original equation and get your final answer
ex: 2(7) - 1/4 = 4 + 1/3(117/4)
14 - 1/4 = 4 + 39/4
55/4 = 55/4 (if both sides of the equation are the same numbers like 55/4 = 55/4 then your answer is true)
Answer:
the opposite of the opposite of -9, the opposite of 6, the opposite of 4, the opposite of 0, the opposite of the opposite of 7
Explanation:
the opposite of 4 = -4
the opposite of the opposite of -9 = -9
the opposite of 6 = -6
the opposite of the opposite of 7 = 7
the opposite of 0 = 0
Then you just put them in order.
Hope this helps!
The property the applies only to addition and multiplication is the commutative property. It means that the numbers can be arranges in any order. so for example you will get the same answer whether you do
5+6 or 6+5
