Which system of equations would represent the scenario below? Amahle is making a 22 pounds of a steel alloy that needs to be 13% magnesium. She has a steel alloy A that contains 21% magnesium and another steel alloy B that contains 9% magnesium. How many pounds of each steel alloy does she need to mix? Let x = pounds of steel alloy A Let y = pounds of steel alloy B

x+y=220.21x+0.09y=2.86

Step-by-step explanation:

i did the test just now

wheres graph

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
