The correct answer is B.
16-9=7
So, 7+9=16.
If we add to 9 only 1 (out of those 7) we have then 10, remaining 6.
9+1=10
Now, if to 10 we add the remaining 6 we will have the final 16.
10+6=16
16-9=7 <=> 9+7=16 <=> (9+1)+6=16
Answer:
3) a<5
5) z≤2
Step-by-step explanation:
3) a/5<1
a<1x5
a<5
5) 5(z+6)≤40
5z+30≤40
5z≤40-30
5z≤10
z≤10÷5
z≤2
60. 1 minute is 1 and 60 is 60. Therefor an hour is 60 times more than 1.
It would just be -14 still
Discussion
The discriminate is b^2 - 4*a*c
The general equation for a quadratic is ax^2 + bx + c
In this equation's case
a = 1
b= -5
c = - 3
Solve
(-5)^2 - 4*(1)*(-3)
25 - (-12)
25 + 12
37
Note
Since the discriminate is > 0, the roots are real and different. The roots do exist and there are 2 of them.
