Answer:
31°
3
108°
Step-by-step explanation:
The measure of angle ADB is congruent to the measure of angle CBD, so it is equal to 31°.
4x = 12
divide by 4 on both sides and you are left with x=3
angle A is congruent to angle C, so it is equal to 108°.
Hope this helps!
 
        
             
        
        
        
Answer:
 f'(x)=-(x+42)/5
Step-by-step explanation:
Rewrite f(x) as y:
y=-5x-42
Flip x and y and solve for y:
x=-5y-42
x+42=-5y
(x+42)/-5=y
So the inverse function is f'(x)=-(x+42)/5 (note that f' means inverse)

This is a part:part ratio. to answer the question, we need to change it into a part:whole ratio. to do this we add up the parts to equal 7. so the ratio of girls to students is 3:7. divide 238 (whole) by 7 (whole) to equal 34. now we multiply 34 by 3 for girls and by 4 for boys. girls: 102; boys: 136.
