Three times Zoey's age plus Ayden's age is equal to 10. Ayden is twice Zoey's age. What is Ayden's age?

A. 2
B. 4
C. 8
D. 12

B - 4

Step-by-step explanation:

Okay let's write this out. 3z+a=10, where Zoey and Ayden are z and a respectively. a=2z

We can further simplify by substtitition.

3z+2z=10

5z=10

3(2) + a = 10

6+a=10

a=4

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
