x = 4.5 so it is 3/-8 = 4.5/12
Have two sets of parallel sides
Hello there.
<span>Solve this equation
3/4(2x+5=14
First, S</span><span>implify both sides
Next, </span><span>Subtract 15 over 4 from both sides.
Then, </span><span>Multiply both sides by 2 over 3
Final Answer: </span>x=41/6
Answer:
x=2 y=-5
Step-by-step explanation:
7x-y=19
2x-3y=19
Multiply the first equation by -3
-3(7x-y)=19*-3
-21x +3y =-57
Add this to the second equation to eliminate y
-21x +3y =-57
2x-3y=19
-----------------------
-19x = -38
Divide by -19
-19x/-19 = -38/-19
x = 2
Now we need to find y
7x-y = 19
7(2) -y =19
14 -y =19
Subtract 14 from each side
14-14 -y=19-14
-y=5
Multiply by -1
y = -5
Answer:
ellen ran faster
Step-by-step explanation:you take the meters ran and devide the number by an amount that would make both the meters ran the same in this case its 400 devided by 2 to give you 200 and because lindsays metres were divided then that means that you devide her time by the amount that you used to devide the metres meaning you devide her time by 2 sixty devided by 2 gives you thirty with ellans 28 sec per 200 metres and lindsays 30 sec per 200 metres than that means that ellan got to 200 metres faster than lindsay.
