Hello from MrBillDoesMath!
Answer:
4
Discussion:
As vertical angles are equal, Angle 3 = Angle 2, so
Angle 3 = 3x + 2 (A)
Angles 3 and 7 are corresponding angles and hence equal. So
Angle 3 = Angle 7 => use (A) above and Angle 7 = x + 10
3x + 2 = x + 10 => subtract x from both sides
3x -x + 2 = x - x + 10 =>
2x + 2 = 10 => subtract 2 from both sides
2x = 10 -2 = 8
x = 8/2 = 4
which is the first choice
Thank you,
MrB
Gave away 7 ⇒ -7
Bought 6 ⇒ + 6
Left with 13
If he did not buy the 6 cars ...
13 - 6 = 7
If he did not give the 7 cars away ...
7 + 7 = 14
He has 14 cars at first.
13 - 6
Answer:
5x - 4y = 0
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
given 0 = - 5x + 4y ( multiply through by - 1 )
5x - 4y = 0 ← in standard form
