To solve this, you plug in the first value (3) for x in the equations and and the second value (-6) for y in the equations! if the two equations then equal each other, it is true! if not, it’s false
Answer:
Your friend is incorrect because if you divide 21 by 7 you will get 3 if you add 7 to 3 you get 10 therefore your friend is incorrect.
3x+ 54=180
straight angle is 180
So just solve the equation.
subtract 54 on both sides.
126=3x
divide that by 3, and you get 42.
check You answer by multiplying 42 And 3, Which basically Is 126
and then 126+54
which is then 180
Answer:
(42, 21) or (–42, –21)
Step-by-step explanation:
let A(x, y), A on line 2y = x
distance
x² + y² = 2205
(2y)² + y² = 2205
y² = 441
y = ±21
x = ±42
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
We first solve the brackets:
(16-9) = 7
Now, we multiply it with 4
Now, we add 3 to it:
Hence, the value of expression would be 31.
Therefore, First option is correct.
