Answer:
No
Step-by-step explanation:
This is not an equation since it does not contain an equal (=) sign and instead contains a less than (<) sign making it an inequality.
We see that both equations have 4y in them. Subtracting the second equation from the first equation, we get (3x -2x) + (4y-4y) = 2 - 8, x = -6
Plugging x = -6 into any equation, we see that our answer is 18 + 4y = 2, 4y = 2 - 18 = -16, y = -4.
Our answer is x = -6, y = -4
Answer:
30 students
Step-by-step explanation:
Yesterday: 1/3 of the 75 students (75 / 3) = 25 students
There are now 50 students remaining to give their speeches.
Today: 2/5 of the 50 students (50 / 5 = 10 x 2 ) = 20 students
50 - 20 = 30 students remaining to give their speeches.
