Answer:
-9a + b
Step-by-step explanation:
For this problem, let us factor out the variable a from the terms containing the variable, and apply addition and the distributive property to simplify the terms.
-5a - 4a + b
= a ( -5 + -4 ) + b
= a ( -9 ) + b
= -9a + b
Hence, the simplified expression for -5a - 4a + b is -9a + b.
Cheers.
Answer:
x= 1/20
Step-by-step explanation:
-1/2x = -10
multiply by 2x on each side
2x(-1/2x) = -10*2x
-1 = -20x
divide by -20
-1/-20 = -20x/-20
1/20 =x
Answer:
1364
Step-by-step explanation:
∑ means that to add values
So n goes from 1 to 5 and you have to add them from 1 to 5
∑n=1 to 5 4^n = 4^1 + 4^2 + 4^3 + 4^4 + 4^5
4^n means that 4 is n times if 4^3 its mean that 4 is 3 times
= 4 + 16 + 64 + 256 + 1024
= 1364 Answer
I hope you got the idea. Thanks
