Answer:
The age of the grinkgo tree is 10 years old and the age of the dogwood tree is 4 years old
Step-by-step explanation:
Let
x -----> the age of the grinkgo tree
y -----> the age of the dogwood tree
z -----> the age of the blue spruce tree
we know that
------> equation A
----> equation B
substitute the value of z
-----> equation C
equate equation A and equation C and solve for y
Find the value of x (equation A or equation C)
therefore
The age of the grinkgo tree is 10 years old and the age of the dogwood tree is 4 years old
Answer: $161
Step-by-step explanation: Subtract $808 from $969
Answer:
Step-by-step explanation:
This is part of the Isosceles Triangle Theorem. If one theta is equal to the other theta (and they are or else they wouldn't both be theta; one would be theta and the other might be beta), that means that the sides across from those congruent angles are also congruent. That means that
6x + 6 = 9x - 9 and
15 = 3x so
x = 5
Answer: I would say the angle would have to be around 85* because with 53 being on the bottom left corner and the 20* at the top and 85 at the left it would be close when you connect them
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
8 = 2^(x + 4)
Rewriting 8 as 2^3
2^3 = 2^(x + 4)
Since the bases are the same, the exponents must be the same
3 = x+4
Subtract 4 from each side
3-4 =x+4-4
-1 =x
