1: -12
2: 3 7/9
3: 7
Step-by-step explanation:
Answer:
3 necklaces and 12 bracelets
Step-by-step explanation:
Bracelets = x +4
amount of necklace gold = 20*x
amount of gold in bracelet = 7*(x+4)
added together = 109 gm
20x + 7(x+4) = 109
20x + 7x+28 = 109
27x+28=109
-28 -28
27x= 81
/27 /27
x=3 necklaces
then bracelets = 3+4=12
Answer:

Step-by-step explanation:
we have

Remember that
To predict a value for y, when x = 4
substitute the value of x in the equation
so

It would be two places to the right of 0 because -3+5=2
D. None. Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees.
Hope this helps!!!!!!
