Answer:

r = 8

Step-by-step explanation:

you start by distributing the 5 to r and -7 to get 3 over 5r - 37. You can then multiply both sides by 5r-37 to get 3 = 5r-37. From here you can add 37 to both sides to get 40 = 5r. From there you divide both sides by 5 to get r = 8

Brainilest!!! 50pts Solve for x and y 45x+(-326y)=96 666x-777y=420

Mila [183]

Multiply the first equation by -666 and the second by 45:-

-29970x + 217116y = -63936

29970x - 34965y = 18900

adding these 2 equations:-

182151y = -45036

y = -0.24724

x = 96 + 326* -0.24724 / 45 = 0.3422

x = 0.342, y = -0.247 Answer (correct to the nearest thousandth)

nadia wants to enclose a square garden with fencing has an area of 141 ft.² to the nearest foot how much fencing will she need e

Andreas93 [3]

We know that area of the square is 141 square feet. Therefore, we can figure out the dimension of square using formula for area as shown below:

$Area=a^{2}\\141=a^{2}\\a=\sqrt{141}=11.874$

We know that fencing is used along the sides of the square. Therefore, amount of fencing required will be equal to perimeter of square.

Hence, we can write:

$\text{Amount of fencing}=\text{Perimeter of square}$

$\text{Amount of fencing}=4a=4(11.874)=47.496$

Upon rounding to nearest foot, we get the amount of fencing required as 48 feet.
