Answer:
Solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation.
Example
1)
2)
Answer:
35
Step-by-step explanation:
Since the sequence is so short, you can simply add the terms. It is convenient to do them pairwise, working inward from the first+last:
(-4+14) +(-1+11) +(2+8) +5
= 10 +10 +10 +5
= 35
__
Or, you can find the average term as the average of the first and last terms:
average term = (-4+14)/2 = 5
Then the sum is the product of this and the number of terms:
sum = (number of terms)×(average term) = 7 × 5 = 35
Answer:
Interval of convergence is 0 </= x < 1
Step-by-step explanation:
Answer:
4(3x+14y)
Step-by-step explanation:
12x +56y
Both terms are divisible by4
4*3x +4*14y
4(3x+14y)
