first, we can distribute the negative into the numbers in parentheses
9x-(4x-1)=2
9x-4x+1=2
now we can combine like terms and then isolate x
5x + 1 = 2
5x = 1
x = 1/5
hope this helps
Answer: Seth is travelling at 63.047mi/hr
Step-by-step explanation: First convert 57.1 seconds to hours.
1 hour is equal to 3600s so multiply 57.1sec by 1hr/3600s to get 0.0158 hr
The formula for speed distance over time. v=d/t
v= 1mi/0.0158hr
v= 63.047mi/hr
Answer:
The number is 6
Step-by-step explanation:
Let's say that the reciprocal of the number is x
1/2 + 3 = 1
3x = 1/2
divided both sides by 3
x = 1/6
Since x is the reciprocal of the number, flip 1/6 and you will get 6/1
6/1 is really just 6 so that's your answer.
Hope this helps :)
5x+2y=29
x+4y=13
Let's eliminate y;
To do so, multiply equation1 by 2;
10x+4y=58
x+4y=13
Subtract equation II from equation I to get;
9x=45
x=5
To solve for y, replace value of x in equation II,
x+4y=13
5+4y=13
4y=8
y=2
