Answer:
437
Step-by-step explanation:
Because if you multiply 63 x 2 = 126
then subtract that from 1000
and get 873
then divide that by 2 and you get 437
Answer:
Answer is A - (1, 3) and (2, 6)
Step-by-step explanation:
(1, 3) • 2
= (1 • 2, 3 • 2)
= (2, 6)
Ratio: 2/2, 6/2
Therefore, the answer is A.
Answer:
-2
Step-by-step explanation:
Take 0 and put it in as x in the equation, you are left with y = ? as -4x0 = 0. When x = 0, y = -2, so -2 would be the answer. You can then check it by plugging x into the equation with -2 and see if you get the y as a result.
Answer:
q = 4.
Step-by-step explanation:
4(q + 1) = 20 Divide both sides by 4:
q + 1 = 5 Subtract 1 from both sides:
q = 4.
A straight line is 180°.
The sum of all the angles in a triangle is also 180°.
Let the missing angle be x°.
For the straight line:
x + 2x²+ 3x+ 6 = 180
x = 180 - (2x² + 3x + 6)
x = 180 - 2x² - 3x - 6
x = 174 - 2x² - 3x
For the missing angle in the triangle:
(174 - 2x² - 3x) + 8x + 3x² - 6x = 180
174 - 2x² - 3x + 8x + 3x² - 6x = 180
174 + x² - x = 180
x² - x + 174 - 180 = 0
x² - x - 6 = 0
(x + 2)(x - 3) = 0
x + 2 = 0 or x - 3 = 0
x = -2 or x = 3
The answer is x = -2 or x = 3
