Answer:
Hello my friend! The answer is 1.75X10^-15
Step-by-step explanation:
If you multiply 2.5 x7 = 17.5
When we do the product of exponential terms with the same base, we can sum de exponents. In this case (-10) + (-6) = -16.
However, to scientific notation, we have to use 1.75
So, the final result wich were 17.5x10-16, will be "1.75x10^-15"
I don't see the problem sorry
Answer:
x = 3y + 5...........1
4x - 2y = - 10...,..2
substituting value of x in equation 2
4(3y+5)-2y=-10
12y+20-2y=-10
10y=-10-20
y=-30/10=-3 is answer
substituting value of y in equation 1
x=3×-3+5=-9+5=-4 is answer
The answer is the third choice they both equal -16/77. Hope this helps:)
Answer:
6+10+14+18+22+26
Step-by-step explanation:
Let n =1
4(1) +2 = 6
Let n = 2
4(2) +2 = 8+2 = 10
Let n =3
4(3) +2 = 12+2 = 14
Let n= 4
4*4+2 = 16+2=18
Let n=5
4*5+2 = 20+2 =22
Let n=6
4(6)+2=24+2=26
Sum these together
6+10+14+18+22+26
