Answer:
39/50
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
0.78=0.781
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100
0.781×100100=78100
Find the Greatest Common Factor (GCF) of 78 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
78÷2100÷2=3950
Therefore
X=3950
In conclusion,
0.78=3950
Is the = -13. Is the response
Step-by-step explanation:
2+6x= -10 + 11(x + 4)
2+ 6x = -10 + 11x + 11(4)
2 + 6x = -10 + 11x + 44
2+ 6x = 11x + 34
6x - 11x = 34 - 2
-5x = 32
x= - 32/5
Answer:
The sum of first five term of GP is 19607.
Step-by-step explanation:
We are given the following in the question:
A geometric progression with 7 as the first term and 7 as the common ration.


Sum of n terms in a geometric progression:

For sum of five terms, we put n= 5, a = 7, r = 7

The sum of first five term of GP is 19607.
Verification:

Thus, the sum is equal to product of 2801 and 7.
