Systems of equation substitution 2x+4y=24 x=4y

Mathematics
1 answer:
antoniya [11.8K]2 years ago
5 0

Answer:

(x, y) = (8, 2)

Step-by-step explanation:

substitute x = 4y into the other equation

2(4y) + 4y = 24

8y + 4y = 24

12y = 24 ( divide both sides by 12 )

y = 2

substitute y = 2 into x = 4y

x = 4 × 2 = 8

solution is (8, 2 )

Usimov [2.4K]
Less than 3 is about 10.75% and greater than 13 is about 6.18%.

To find these percents, you need to find the z-score for each value. Then, use your table to find the correct percent. Be sure to find the side above 13 when you use your chart.

For less than 3:
(3 - 7.45) / 3.6 = -1.24 = The percent below this is 0.1075

For greater than 13:
(13 - 7.45) / 3.6 = 1.54 = The percent above this is 0.0618

Tresset [83]
Original:
<span>The width and length of a rectangle are consecutive odd integers
</span>so W = x and L = x + 2

<span>If the length is increased by 5 feet, then new L = x + 2 + 5 = x + 7
</span>
A = L x W
60 = (x + 7) x
60 = x^2 + 7x
x^2 + 7x - 60 = 0
(x - 5)(x + 12) = 0
x = 5 and x = -12

From here you have x = W = 5 ft and L = x + 2 = 5 + 2 = 7 feet

Area of original = 5 x 7 = 35

answer 
<span>the area of the original rectangle: </span>35 ft^2
