Answer:
triangal
Step-by-step explanation:
Looking at these two equations, you need to cancel out the variables with powers and the z. This can be simply done by adding them.
9y-2y^2+3z^2=867
+
9x+2y^2-3z^2=132
-----------------------------
9y+9x=999
Factor the 9 out of the left side.
9(x+y)=999
x+y=111
The answer is C (111).
False because 10 times as much as 600 is 6,000 because as much means to multiply so you multiply 10 by 600 and get 6,000
Answer:
9 two year olds, 18 three year olds, 18 four year olds
Step-by-step explanation:
Let's say x is the number of 2 year olds. There are double the number of three year olds (2x) . Four year olds is the same as 3 year olds (2x).
x + 2x +2x = 45
5x=45
x= 9
Double is 18 for 3 and four year olds.
6) Being that x=0 , angle R will be equal to 65.
7) Being that x=2, angle N will be equal to 116 .
Note that : adjacent angles (the ones next to each other) adds up to 180 & opposite angles are congruent meaning that they equal each other.
