Answer:
x = -22.5
Step-by-step explanation:
-0.4x - 3.1 = 5.9
+3.1 +3.1
-0.4x = 9
/-0.4 /-0.4
x = -22.5
Step-by-step explanation:
So you have 31/40
3/4=30/40 (multiply by 10/10)
4/5=32/40 (multiply by 8/8)
So, there you have it, 31/40 is right in between those two.
turn it into decimal format. just do the division,. 31 divided by 40 = .775 and 3 divided by 4 = .75 and 4 divided by 5 = .8. all you have to do is the division and once it is in decimal format you can tell which is greater. hope this helps
X = 12 because x+3 is equal to 15
X(x+5) is equal to x exponent 2 +5x
