Answer:
RC',180° rm
Step-by-step explanation:
5p-9=2p+12
+9 +9
5p= 2p+21
-2p -2p
3p/3=21/3
p=7
Simplifying
2x + -1y + -3z = 5
Solving
2x + -1y + -3z = 5
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
2x + -1y + y + -3z = 5 + y
Combine like terms: -1y + y = 0
2x + 0 + -3z = 5 + y
2x + -3z = 5 + y
Add '3z' to each side of the equation.
2x + -3z + 3z = 5 + y + 3z
Combine like terms: -3z + 3z = 0
2x + 0 = 5 + y + 3z
2x = 5 + y + 3z
Divide each side by '2'.
x = 2.5 + 0.5y + 1.5z
Simplifying
x = 2.5 + 0.5y + 1.5z
Answer:
0.422
Step-by-step explanation:
(0.45)(0.62) + (0.55)(0.26) = 0.422
Answer: x<7 (x = all answers)
Step-by-step explanation:
(3x-3) < 18 = 3x-3 < 18
3x-3 < 18
+3 +3
3x < 21
3x/3 < 21/3
x<7
All answers are correct because they are all negative, which means they are less than 7.
