Answer:
Option F
Step-by-step explanation:
F). x + y = 3 -------(1)
x - 3y = -2 --------(2)
Equation (1) minus equation (2)
(x + y) - (x - 3y) = 3 - (-2)
4y = 5
y = 1.25
Hence, y is positive.
G). x + y = 3 --------(1)
x + y = -2 --------(2)
Both the equations represent parallel lines.
There are no solutions of the given equations.
H). x - 3y = -2 -------(1)
x + y = -2 -------(2)
Equation (2) minus equation (1)
(x + y) - (x - 3y) = -2 - (-2)
4y = 0
y = 0
Since, 0 is neither positive nor negative, y will be neither positive nor negative.
J). x + y = 3 -------(1)
x - y = 3 --------(2)
Equation (1) - Equation (2)
(x + y) - (x - y) = 3 - 3
2y = 0
Hence, y is neither negative nor positive.
Therefore, Option F is the answer.
Answer:
The equation to this word problem are:
x ≥ 30 ...... (1)
x ≥ y ...... (2)
x + y ≤ 100 ..... (3)
Step-by-step explanation:
Here, the given question is INCOMPLETE.
A private school admits no more than 100 students every year. additionally, at least 30 of these students must be girls, x and the school admits at least as many girls as boys, y. What are the equation to this word problem.
Let us assume the number of girls admitted in the school = x
At least 30 of these students must be girls.
⇒ x ≥ 30 ...... (1)
Let us assume the number of boys admitted in the school = y
The school admits at least as many girls as boys.
⇒ x ≥ y ...... (2)
Also, TOTAL STUDENTS = No more than 100
So, Total Number of ( Boys + Girls) ≤ 100
⇒ x + y ≤ 100 ..... (3)
Hence, the the equation to this word problem are:
x ≥ 30 ...... (1)
x ≥ y ...... (2)
x + y ≤ 100 ..... (3)

30 divided by 100 = 0.3 x 7.5 = 2.25 or 25%
Answer:
Closer to 30.
Step-by-step explanation:
To answer this first find 40% of 90.
90*0.4=36
0.4 is the same as 40%
