Answer:
-26
Step-by-step explanation:
Sum is the addition of two or more integers. The sum of negative and positive integers must always consider the sign before a number for the given numbers, we shall add them one by one as follows
-18+12=-6
-6+-27=-33
-33+-9=-42
-42+16=-26
Therefore, the sum is -26 which is not among the options given although this is the right answer
That is finding the least common multiplier of 12 and 8, and that is 24:
1/12 = 2/24
3/8 = 9/24
Answer:
Step-by-step explanation:
To have a complete value of angle, it must always go up to 180°
<u>Therefore:</u>
We already know one value and it is 44°
180° - 44° = 136°
<u>Then since we have to n values left, we divide 136° by 2 to get the result:</u>
136° / 2 = 68° each
<u>Check our work:</u>
<u></u>
44° + 68° + 68°
=> 180°
Part A
Total number of litres in the punch = grape juice + lemon lime soda
let grape juice be
, and lemon-lime soda be
the expression for the total number of litres in the punch is given by
We know the number of litres for the lemon-lime soda, hence the expression is
Part B:
40% of the punch is lemon-lime soda which is 2 litres
That means every 1 litre represents 20% of the punch
60% of the punch is grape-juice, hence 60÷20 = 3 litres of grape juice
