Answer:-8
Step-by-step explanation: you add -1+ -1, to get -2, then -2+-2, to get -4 and so forth.
Answer:
a = -3
Step-by-step explanation:
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other.
Divide -8 from both sides:
(-8a)/-8 = (24)/-8
a = 24/-8
a = -3
a = -3 is your answer.
Answer:
The second one, I got that question
x ≤ 10
Step-by-step explanation: you need to find out the variable w/ with six to get you to the number 16.
Answer:
22.6 degrees
Step:
The hypotenuse is 13cm using pythagoras theorem.
Now, finding the smallest angle is by using;
SOH
sin = opposite over hypotenuse
Thus, cos^-1 (12/13)
=22.61
and equals to 22.6 (1d.p)
