Answer: -15
Step-by-step explanation:
Let the unknown number be 'x'
Using the statement we can form the equation:
4 + x = -11
Now, solve the above equation to get :
x = -11 -4
x = -15
The number is -15. To check our answer, substitute for x :
4 + (-15) = -11
4 - 15 = -11
The above equation is correct. Therefore, the number is -15.
Answer:
y=30
x=60
The triangle has all sides equal therefore all the angles are equal.
For all the angles to be equal and add up to 180 (sum of angles in a triangle is 180), each angle has to be 60.
Therefore y=90-60
=30
x=180-(30+90)
=60
27 ÷ (-2 + (-7))
27 ÷ (-9)
-3
The answer is -3. Hope that helps!
