The perimeter of a rectangle is 66 cm.if the width of the rectangle is three more than half the length,find the length of the re
hoa [83]
<span>Let us use the variable x for length. So width will be 1/2x + 3. Perimeter = x+x+ 1/2x + 3 +1/2x + 3 = 3x + 6 = 66 Therefore 3x = 66-6 = 60 So x = 60/3 = 20 The length is 20 cm. Therefore the width = 1/2 of 20 + 3 = 10 + 3 = 13 cm Check: 20+20+13+13 = 66</span>

Y=99.99+23.75(x-1) as a Y=ax+b equation
Hatshy [7]

Answer:

y = 23.75x  + 76.24

Step-by-step explanation:

We want to rewrite

y = 99.99 + 23.75(x - 1)

in the form

y = ax + b

We expand to get:

y = 99.99 + 23.75x - 23.75

Regroup similar terms:

y = 23.75x - 23.75 + 99.99

Simplify:

y = 23.75x  + 76.24

This is now of the form

y = ax + b

where a=23.75 and b=76.24
