1/2 - 2/15= 15-4/30 = 11/30 this means that if you were to add 11/30 to 2/15 is exactly equal to 1/2, to fully answer your question you can use any value above that like 12/30 (keep in mind you have to simplify) = 6/15 = 2/5. But then again your question says to add any number to make it greater than 1/2 so technically you could just add 100 or 200 or 1/2 to make the sum of it greater than one half
Answer:
16
Step-by-step explanation:
x+6
In this step instead of puting x you relace it with 10 which is what x equals
10+6
16
Start by writing your own expression.
x is the smaller number and x + 1 is the next number
x(x + 1) = 420
x^2 + x - 420 =0 ⇒ constant = -420
Answer:
x = -6
Step-by-step explanation:
Distribute the 2 into the brackets:
2x + 10 = -2
leave the 2x alone on one side:
2x = -2 -10
2x = -12
divide both sides by 2:
x = -6
Answer:
infinite number of solutions
Step-by-step explanation:
Given the 2 equations
4x + 6y = 12 → (1)
6x + 9y = 18 → (2)
Equation (2) is a multiple of (1)
Each term has been multiplied by 1.5
Thus the 2 equations are basically the same equation.
This indicates there are infinite solutions to the system
