Answer:
1. 7.1
2. 11.5
3. 24.2
Step-by-step explanation:
you use P.E.M.D.A.S. for all the equations.
so you do thr multiplication and then the addition
1. 2(1.8)+3.5= 3.6+3.5= 7.1
2. 2(4)+3.5= 8+3.5=11.5
3.2(6.9)+3.5= 13.8+3.5= 24.2
hope this helps
Answer:
-2, -1, 0, 1
Step-by-step explanation:
Let the 4 numbers be x,x+1, x+2, x+3
Then we have the equation:-
5(x+3)-2(x+1) = 7
5x - 2x + 15 - 2 = 7
3x = - 6
x = -2
so the integers are -2, -1, 0, 1
You just have to try them all:
Y=x+3 ≈ 6=3+3 ≈ 6=6 √
Y=x+3 ≈ 8=4+3 ≈ 8=7 X
So the first function doesn't work
Y=2x ≈ 6=2(3) ≈ 6=6 √
Y=2x ≈ 8=2(4) ≈ 8=8 √
Second function works
Y=x+4 ≈ 6=3+4 ≈ 6=7 X
Third function does not work
Y=12-x ≈ 6=12-3 ≈ 6=9 X
Fourth function doesn't work
So your answer is Y=2X :)
Well, you can put various math problems into one. Equations can also show more information easier than writing many problems. Hope this helps, and keep learning!
