Let x be the amount of Ann money, y be Jessica's money and z Mary money.
30% of z equates 0.3*z.
Ann has 30% less than z so: x = z - 0.3z = 0.7z.
70% of z equates 0.7z.
"Jessica has 70% more than Mary " we deduce the equation: y =z+0.7z= 1.7z.
Signe the total is $102, we deduce the equation x+y+z = 102.
x=0.7z and y=1.7z then 0.7z+1.7z+z=102, therefore 3.4z=102 then
z =102/3.4 = $30.
x=0.7*30= 21 and y=1.7*30=51.
Ann has $21, Mary has $30 and Jessica has $51.
Answer: 8/5 or 1 3/5
Step-by-step explanation:
2/5 + 2/5 + 2/5 + 2/5
8/5 which is 1 3/5
Answer:
5) C pink 6) A -1/2x + 1/4 7) D z ≥ 0
Step-by-step explanation:
5) White 1/6 = 4/24
Green 1/3 = 8/24
Pink 1/8 = 3/24
Yellow 3/8 = 9/24
6) 11/2x - 2(3x - 1/8) Distribute the -2
11/2x - 6x + 1/4 Combine like terms
-1/2x + 1/4
7) z ≥ 0
z is greater than or equal to 0
