Answer:
all the angles add up to 180 degrees
So 180÷6=30
(i got 6 cuz 1+2+3)
so 1=30
2=30*2=60
3=30*3=90
The term in that equation is 3x 7x and -9 hope this helps
Answer:
what's the question?? I b.d ont get it
27.75/5 = $5.55 per book
32.16/6 = $5.36 per book
The online store is the cheapest because it has the lowest unit rate
To solve for x, you first add 5 to both sides so it remains equal.
3 + x = 2
Then you simply subtract 3 on both sides.
x = -1
Substitute your solution into the equation and see it is true.
|3+(-1)) - 5 = -3
The equation is true, therefore your answer is: x = -1
