First, let's solve the inequality:
<span>x - 3 < -9
//add 3 to both sides:
x<-6
the second inequality:
x + 5 ≥ 10</span>
//substract 5 from both sides:
<span>x ≥ 5
So we need to map:
</span>
<span>x<-6
</span><span>x ≥ 5
Now, shading will be to the leftof -6 and to the right of 5 - this is compatible with answers A and B.
A closed circle means that the number is included, so the correct answer is A!</span>
Answer:
6%
Step-by-step explanation:
This should be the formula I believe. Solve for x now.
x = 9
Answer:
9 :)
Step-by-step explanation:its 9
Answer:
A: 68.25 minutes
B: 12 times
C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.
Step-by-step explanation:
a: 72 -0.75*5 = 68.25
b: M=63=72-0.75n
subtract 72 from each side: -9 = -0.75n
divide each side by -0.75: n = 12
so 12 times
c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.
