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 :
4 + x = -11
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:
I think it's B

Since that is the opposite like it says
Answer:
D. DE = 24 yd, EF = 10 yd
Step-by-step explanation:
Solve for the unknown angles by setting up common ratios and cross multiplying. You can use this method because they are similar triangles.
For example, DE can be found by setting the ratios of AC/AB equal to the ratio of DF/DE.
13/12 = 26/x
Simply solve for x!
