Answer:
X=61.2
Step-by-step explanation:
x/85 = 72/100
x*100/8500 = 6120/8500
x*100 must equal 6120 therefore x must be 61.2 because 61.2 * 100 is 6120
Answer:
z+y/5=x or z/5 + y/5 = x
Step-by-step explanation:
z=5x-y
add y to both sides
z+y=5x
divide both sides by 5
z+y/5=x or z/5 + y/5 = x
Simplifying
2ab + 4ab = 0
Combine like terms: 2ab + 4ab = 6ab
6ab = 0
Solving
6ab = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Divide each side by '6'.
ab = 0
Simplifying
ab = 0
Answer:
0.7% I think
Step-by-step explanation:
1) x = - 4, y = - 12; (- 4, - 12)
2) x = 34, y = 17; (34, 17)
3) x = 16, y = 7; (16, 7)
4) x = 7, y = - 4; (7, - 4)
5) x = - 4, y = 10; (- 4, 10)
6) x = 12, y = - 7; (12, - 7)
7) x = 5, y = 10; (5, 10)
8) x = 11, y = - 12; (11, - 12)
