Answer:
h = 1 2/3
Step-by-step explanation:
1/2 (5-2h) = h/2
Multiply each side by 2
(5-2h) = h
Add 2h to each side
(5-2h +2h) = h+2h
5 = 3h
Divide by 3
5/3 = 3h/3
5/3 =h
1 2/3 = h
Check
1/2 (5-2*5/3) = 5/3/2
1/2 ( 5 - 10/3) = 5/6
1/2 ( 15/3 - 10/3) = 5/6
1/2 ( 5/3) = 5/6
5/6 = 5/6
Hello
-4x + 11y = 15
x = 2y
Ok, we need to solve x = 2y for x
Lets start by substitute 2y for x in -4x + 11y = 15
-4x + 11y = 15
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15
Divide both sides by 3
3y/3 = 15/3
Y = 5
Again, substitute 5 for y in x= 2y
x = 2y
x = 2(5)
x = 10
Final answer : X = 10 and y = 5
Good luck!
All the fractions that you are subtracting have the same denominator so you just subtract the numerator.2/5-1/5=1/5
3/8-2/8=1/8
79-3/9 since you can simplify 3/9 by 3 you get 1/3 you get 79/1-1/3.the common denominator is 3 so you multiply 79/1 by 3 and 1/3 by 1 and then you get 237/3-1/3 and you get 236/3. then you turn it from an improper fraction into a mixed number. 236 divided by and you get 78.6 repeating
