$\\ \rm\Rrightarrow 8=3(6x-3)$

$\\ \rm\Rrightarrow 8=18x-9$

$\\ \rm\Rrightarrow 18x=17$

The value of y is directly proportional to the value of x. If y = 35 when x = 140, what is the value of y when x = 70?

antiseptic1488 [7]

Answer:

y = 17.5

Step-by-step explanation:

Use the direct proportion equation, y = kx

Plug in the x and y values to solve for k

y = kx

35 = k(140)

0.25 = k

Then, plug in the k value and given x value into the equation, and solve for y

y = kx

y = 0.25(70)

y = 17.5

A rectangular banner covers an area of 2 7/8ft2. The length of the banner is 3/4ft. What is the width of the banner in ft?

hichkok12 [17]

Answer:

Width of the rectangular banner is $3\frac{5}{6}$ ft.

Step-by-step explanation:

Area of the rectangular banner = $2\frac{7}{8}$ square feet

= $\frac{23}{8}$ square feet

Area of rectangle is given by,

Area = Length × Width

Length of the banner = $\frac{3}{4}$ feet

From the formula,

$\frac{23}{8}=\frac{3}{4}\times W$

W = $\frac{\frac{23}{8} }{\frac{3}{4} }$

= $\frac{23}{8}\times \frac{4}{3}$

= $\frac{23}{6}$

= $3\frac{5}{6}$ ft

Therefore, width of the rectangular banner is $3\frac{5}{6}$ ft
