A rectangle length is 8cm more than three times it’s widith. The perimeter is 128 cm find the length.
Masteriza [31]
Let x = width
<span>length is 8 cm more than three times it’s width so length = 3x + 8
</span>
Perimeter of a rectangle = 2(L + W)
so
128 = 2(x + 3x + 8) solve for x (width)
128 = 2(4x + 8)
  64 = 4x + 8
  4x = 56
    x = 14
width = 14 cm
length = 3(14) + 8 = 50 cm

Answer:
width   = 14 cm
length  = 50 cm

Evaluate<br> 5-(2w-8)=6w-9
Brilliant_brown [7]

Step-by-step explanation:

Steps

5−(2w−​8)=6w−9

Show Steps

Expand 5−(2w−8):    −2w+13

−2w+13=6w−9

Subtract 13 from both sides

−2w+13−13=6w−9−13

Simplify

−2w=6w−22

Subtract 6w from both sides

−2w−6w=6w−22−6w

Simplify

−8w=−22

Divide both sides by −8

−8w

−8 =

−22

Naomi and Josiah work at a furniture store. Naomi is paid $190 per week plus 5.5% of her total sales in dollars, x x, which can
Ivanshal [37]

Answer:

x = $11400

Step-by-step explanation:

Naomi is paid $190 per week plus 5.5% of her total sales in dollars, x, which can be represented by g ( x ) = 190 + 0.055 x.

And Josiah is paid $475 per week plus 3% of his total sales in dollars, x, which can be represented by f ( x ) = 475 + 0.03 x

Let the weekly pat for them are equal.

Then, g(x) = f(x)

⇒ 190 + 0.055 x = 475 + 0.03 x

⇒ 0.025 x = 285

⇒ x = $11400

Therefore, for the value of x = $11400, that will make their weekly pay the same. (Answer)

Find the value of r so that the line that passes through (5, r) and (2, -3) has a slope of 4/3
ZanzabumX [31]

slope = (y2 - y1)/(x2 - x1)

4/3 = (-3 - r)/(2 - 5)

4/3 = (-3 - r)/(-3)

-4 = -3 - r

-1 = -r

r = 1
