So basically here is the answer mate!
2x + 7y = 3-------------------------(substitute x's value here, i.e., x = -4y)
2( -4y ) + 7y = 3
-8y + 7y = 3
-1y = 3
y = -3------------------------( 1 )
Since x = -4y
= -4 ( -3 ) --------------------------( since we found the value of y)
= 12
Here is the answer for x = 12 , y = -3
Mark my anwer as the brainliest please ! :)
Answer: Side p = 33.9 mi
Step-by-step explanation: The figure in the question is a trapezoid with the area already given as 792.965.
The unknown side p is one of the two bases (parallel lines) in the trapezoid. The area of a trapezoid is given as
Area of trapezoid = {(a + b)/2} x H
Where H is the vertical height and a and b are the parallel lines
The area of the trapezoid can now be properly expressed as
792.965 = {(15.2 + p)/2} x 32.3
By cross multiplication we now have
792.965/32.3 = (15.2 + p)/2
(792.965/32.3) x 2 = 15.2 + p
49.1 = 15.2 + p
Subtract 15.2 from both sides of the equation
33.9 = p
Therefore the missing length (side p) equals 33.9 mi
Answer:
Probability = 2/13 ≈ 15.4%
Step-by-step explanation:
We are looking for probability of drawing an ace or king from a standard deck of cards.
In a standard deck of cards, there are <em>4 ace and 4 king</em>.
4 + 4 = <u>8</u>, this is the number of possible "correct" cards you can draw, which satisfy the conditions.
Since a standard deck has <em>52 cards</em>, this is the number of cards you can draw, the "possible outcomes".
Probability is the <u>number of "correct" outcomes divided by the total possible outcomes</u>.
The probability is 8 / 52, but we need to <u>reduce the fraction</u>.
Both numerator and denominator are divisible by 4.
8 / 52 = 2 / 13
If you want the probability as a percentage, divide 2 by 13 and multiply by 100.
Probability = 2/13 ≈ 15.4%
