It could be any time, but I would say 10. 10*10=100
hope it helps!
Answer:
Equation: x+3<12 Answer: x<9
Step-by-step explanation:
SO bascially what you do is you find the equation based on the wording (The sum of a number and three is less than twelve) and after you find the equation (which is x+3<12), you subtract 3 from both sides, getting x<9
Hope this helps:)
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 2 √ 3 , − 2 √ 3
The linear rule should look like this y=a*x+b
As the function graph goes through the (0,0) point, the equation 0=a*0+b <=> b=0 must be true.
Now we only need to find a, using one of the points given. With (-4, 16):
16=-4*a <=> a=16/-4 <=> a= -4
So the rule looks the following way:
f(x)= -4*x
You have to solve for x.
1/2x - 6.5 > 12
+6.5 +6.5
1/2x > 18.5
2(1/2x) > 2(18.5)
x > 37
