The perimeter of a rectangular field is 328 yards. If the length of the field is 89 yards, what is its width?

miv72 [106K]

Set up an equation based on the information given

$89 + 89 + x + x = 328$

Combine like terms

$89 + 89 = 178$

$x + x = 2x$

$2x + 178 = 328$

Solve

$2x + 178 = 328$

$328 - 178 = 150$

$2x = 150$

$x = 75$

Answer

The width of the rectangular field is 75 yards.

What is the slope intercept and point slope form

noname [10]

Slope intercept is y=Mx+b where m is always the slope and b is always your y intercept. The point slope fo is y-y^1=m(x-x^1) where x1 and y1 are a known point and m is the still the slope. X and y is another point on the linear equation

The ratio of the number of boys to the number of girls inn math club is 4 to 3 there are 36 girls in math club how many boys are

Kay [80]

Answer:

48 boys

Step-by-step explanation:

Since the ratio of Boys to Girls is 4/3, set this equal to X number of boys/36. Cross multiply so 36*4=144, and 3*x= 3x. So now you have 144=3x, divide by 3 to get x=48 boys.

What is the inverse of this function

just olya [345]

G(x) = (25 - x)/5     First lets call g(x) by its other name - y

y = (25 - x)/5         Now switch the x and y

x = (25 - y)/5        Solve for y which is now the inverse - call this $g^{-1}(x)$

5x = 25 - y
y = 25 - 5x      this is the inverse so $g^{-1}(x)$ = 25 - 5x
