Answer:
C.
Step-by-step explanation:
You are given 3x-4y<16 and we want to see which of the ordered pairs is a solution.
These ordered pairs are assumed to be in the form (x,y).
A. (0,-4)
?
3x-4y<16 with (x=0,y=-4)
3(0)-4(-4)<16
0+16<16
16<16 is not true so (0,-4) is not a solution of the given inequality.
B. (4,-1)?
3x-4y<16 with (x=4,y=-1)
3(4)-4(-1)<16
12+4<16
16<16 is not true so (4,-1) is not a solution of the given inequality.
C. (-3,-3)?
3x-4y<16 with (x=-3,y=-3)
3(-3)-4(-3)<16
-9+12<16
3<16 is true so (-3,-3) is a solution to the given inequality.
D. (2,-3)?
3x-4y<16 with (x=2,y=-3)
3(2)-4(-3)<16
6+12<16
18<16 is false so (2,-3) is not a solution to the given inequality.
6.) 9
5(9)+18=63
Divide 9+13x (since its the entire line) by 2 to get 4.5+6.5x so it can equal Half
4.5+6.6(9)=63
7.) IF=HF
The three lines indicate they are equal to eachother
Hope that helps!
Answer:
60
Step-by-step explanation:
let X be the total number of students.
48÷x *100 = 80
4800= 80x
X = 60 students
This is pretty simple. This requires the order of operations. So for the order of operations, it basically tells you the order on how you solve operations.
The first order is brackets, the second one is division, the third one is multiplication and the fourth one is addition or subtraction.
For this case, you have { 6-4 }. 6-4 is on brackets, so you have to solve it first. The answer is 2.
After that, you can divide 50 by 2, which gives you 25.
I hope I have been helpful. Good luck! :)
