Answer:
5.5
Step-by-step explanation:
So, this is a simple factoring problem. The answer is 5.5(2x-1). So, heres how we get that answer.
So, factoring is basically breaking down the problem into smaller parts. So once we simplify the problem, we can factor it.
Simplify by combining like terms: 5x+6x= 11x and -2.5-3=-5.5
Now we have 11-5.5=?
so, we need to have (2x-1) in our answer because the problem asks for that in the answer.
We need to find a number that satisfies the equation and answer
so, 5.5(2x) is 11x, and 5.5(-1) is 5.5.
5.5 satisfies the equation, therefore is the answer
Answer:
The answer is 1800.
Step-by-step explanation:
3/540 = 10/x
3x = 540 × 10
x = 5400/3
x = 1800
Answer:
I think A
Step-by-step explanation:
sorry if it is not correct hope it helps
So first we were to told that the sum of 2 numbers add to 19
a+b=19---------(1)
and they subtract to 5
a-b=5-----------(2)
These are two simultaneous equation and can be solved by elimination:
(1) + (2):
(a+b)+(a-b)=19+5
2a=24
a=12
12+b=19
b=7
So the two numbers are 12 and 7
