Answer:
-3
Step-by-step explanation:
5-2 is three
3 times -2 is -6
-9-(-6) is -3
(2,-3)
This is true.
x+7=8.3. Remove 7 on both sides :x=8.3-7=1.3
Answer:
70% of the meeting is left.
Step-by-step explanation:
Hi, to answer this question, first, we have to convert the hours to minutes.
Since 1 hour = 60 minutes
For 2 hours:
1 /60 = 2/x
x = 2 (60)
x = 120 minutes
So, a scout meeting last 120 minutes (2 hours)
36 minutes already spent.
120-36 = 84 minutes left
So, if 120 is the 100% of the meeting, for 84 minutes:
120/100 = 84/x
1.2 =84/x
x = 84/1.2
x = 70%
70% of the meeting is left.
R example: 6 1/2 = 13/2 = 6.5
For the first example, six and a half is equal to thirteen halves, which
is then equal to six point five. To do this, the rule to turn a mix
number into a fraction is by multiplying the 2 with the 6 and then add
the answer to 1, which gives 13/2 (Remember to always give the same
denominator). Finally, thirteenth halves is equal to six point five
(because when you divide 13 by 2, you get 6 and one left over. To
continue dividing, add a 0 , and so 10 goes into 2 is five. so the
decimal is 6.5
