I don’t understand either
Answer:
2934.5
Step-by-step explanation:
2934.46692 Rounded to 1 Sig Fig is 2934.5
A) 4a+3w
b) 2b+h
c) 3(w+h)
d) (4a+3w)(2b+h) - 3(w+h)
just expand brackets for d and simplify
3x + y = -3
-2x + y = 7
Use elimination method
Subtract both equations
5x = -10, x = -2
Plug in -2 for x (any equation)
3(-2) + y = -3
-6 + y = -3
y = 3
Solution: x = -2, y = 3
Or as a coordinate: (-2, 3)
Step-by-step explanation:
2x+98=180° (angles in straight line )
2x=180-98
x=2/2
x=1
