Answer:
a. 2:3, b. 25 students, c. 3:2
Step-by-step explanation:
a. 5 (total) - 2 (with glasses) = 3 (without glasses), making the ratio 2:3.
b. We can assign the total students with the variable x. 3:5=15:x, 75=3x, x=25. 25 total students.
c. 25 (total students) - 15 (without glasses) = 10 (with glasses). (10+5):(15-5) is 15:10, which, when simplified, equals to 3:2.
Answer:
(2, 9)
x = 2
y = 9
Step-by-step explanation:
To solve this system, we can either use substitution or graph it. I will be showing how to graph it.
To solve by graphing, we graph both of the equations and find the point at which the lines intersect.
