No, greens are not correct
Cheeseburgers = $2.79
Fries = $1.79

Greens - 5c + 4f = $21.11
Browns - 4c + 3f = $16.53
If each cheeseburger = $2.49 and
each medium fries = $2.87, then
5 x (2.49) + 4 x (2.87) = $23.93
$23.93 is not equal to $21.11

Write the word sentence as an equation. Then solve the equation. A number multiplied by 2/3 is 3/20.

vaieri [72.5K]

Answer:

Equation = X*(2/3) = 3/20

Solve for X = 0.23

Step-by-step explanation:

Let, the number be "X"

According to the question,

X*(2/3) = 3/20..........(i)

From equation (i), we can get,

X = (3/20)/(2/3)

or, X = 0.15/0.66

or, X = 0.23

Alternative way,

Let, the number be "X"

According to the question,

X*(2/3) = 3/20..........(i)

From equation (i), we can get,

X = (3/20)/(2/3)

or, X = (3/20)*(3/2)

or, X = 9/40

or, X = 0.23

The length of a rectangle is four times its width. If the area of the rectangle is 324m^2, find its perimeter.

Anuta_ua [19.1K]

Answer:

$perimeter=90$

Step-by-step explanation:

We know that the length is four times the width, so:

$l=4w$

We also know the area, which is 324 m². The formula for area:

$A=l*w$

Insert the known values:

$324=(4w)*w$

Solve for w. Simplify by removing parentheses:

$324=4w*w\\324=4w^2$

Divide 4 from both sides to isolate the variable:

$\frac{324}{4}=\frac{4w^2}{4} \\\\81=w^2$

Find the square root of both sides:

$\sqrt{81} =\sqrt{w^2} \\\\w=9$

The width is 9 m.

We know the width. Now find the length by using the area formula and inserting known values:

$324=l*9$

Solve for l. Divide both sides by 9:

$\frac{324}{9}=\frac{l*9}{9}\\\\ l=36$

The length of the rectangle is 36. (You can check: 4 times 9 is 36)

Now find the perimeter:

$P=2l+2w$

Insert values:

$P=2(36)+2(9)\\\\P=72+18\\\\P=90$

The perimeter is 90 m.
