A rectangle has a length of 14 yards less than 9 times its width. If the area of the rectangle is 6183 square yards, find the le

Jlenok [28]

Answer:

$l=238\ yards$

Step-by-step explanation:

From the question we are told that:

Area of Rectangle A=6183

Equation of Length

$l=9w-14$

Where

$w=width\ of\ triangle$

Generally the equation for Area of Rectangle is mathematically given by

$A=(9w-14)w$

$A=9w^2-14w$

$6183=9w^2-14w$

$9w^2-14w-6183=0$

$w=28$

Therefore

$l=9(28)-14$

$l=238\ yards$

Nutka1998 [239]

Answer:

New balance = -151.89 + 4.5x

(where x is the value of the smaller deposit)

Step-by-step explanation:

The inicial balance was -126.89.

Then, it were made two deposits, one with the value of x, and one that is 3 1/2 times the other, that is, 3.5x.

Then, the customer made a withdraw of $25.

So, The new balance can be calculated as:

New balance = inicial balance + x + 3.5x - 25

New balance = -126.89 + 4.5x - 25

New balance = -151.89 + 4.5x

Will the solution of an equation such as x-3=9 be a variable on a number? Explain

KengaRu [80]

X= 12
Add three on both sides to get rid of it
9+3 and -3 + 3 the three is negative because you drop the minus sign down
This cancels out the three and 9+3 is 12 so X=12
