Answer:

Let it be x the number.

We have to sum to x two fifths of him and we know the result is 70, so:

x + \frac{2}{5}x = 70

We could also solve it:

\frac{5x}{5}+\frac{2x}{5}=\frac{350}{5}

5x + 2x = 350

7x = 350

x=\frac{350}{7}=50

The chocolate Shoppe has a rectangular logo for their business that measures 2 1/2 feet tall with an area that is exactly the ma
Ilya [14]

The equation that could be used to determine L, the unknown side length of the logo is A =2.5w

<h3>How to determine the equation?</h3>

The given parameters in the question are:

  • Shape: Rectangle
  • Height of logo, h = 2 1/2 feet

From the question we understand that the area is at maximum.

Represent this area with A

The area of the rectangle is:

A = h * l

Where h and l are the dimensions of the rectangle.

Substitute 2 1/2 for h

A = 2 1/2 * l

Express 2 1/2 as a decimal number

A = 2.5 * l

Evaluate the product

A =2.5l

Hence, the equation that could be used to determine L, the unknown side length of the logo is A =2.5w

PLSS HELP ITS DUE IN HALF AN HOURRR!!
natulia [17]

Answer

A

Step-by-step explanation:

$\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad6\frac{2}{3}=\frac{20}{3}$

=8\div \frac{20}{3}

=\frac{8}{1}\div \frac{20}{3}

=\frac{8}{1}\times \frac{3}{20}

=\frac{2}{1}\times \frac{3}{5}

=\frac{2\times \:3}{1\times \:5}

=\frac{6}{1\times \:5}

=\frac{6}{5}

Convert improper fractions to mixed numbers

=1\frac{1}{5}

The lines s and t intersect at point R.<br><br> What is the value of y?<br><br> y = ____
ozzi
Assuming that the angles are congruent, then y = 29.
4y - 8 = 79 + y
4y = 87 + y             Add 8 to both sides
3y = 87                  Subtract y from both sides
y = 29
