Multiplying fractions: multiply numerators and multiply denominators
1. 3/4 X -6/7 = -18/28 = -9/14
2. -2/7 X -3/7 = 6/49
3. 4 because 72/9 is 8. -72/-9 is 8. Two negatives makes a positive when multiplying and dividing.
Answer:
A number sequence is a list of numbers that are linked by a rule. If you work out the rule, you can work out the next numbers in the sequence. In this example, the difference between each number is 6. So the rule for this sequence is to add 6 each time. So now you can work it out the next number. 27 + 6 = 33.
True
if the lines are paralell, there is no intersection and therefor no solution
example
y=3x+4
and
y=3x+10
or
3x+2y=4 and
3x+2y=9
true
( the answer is 15) because in a equilateral all angles are equal and in the right triangle you already have 1 angle so just divide by 2 you get 45 so subtract 45 from 60
