What does a decimal between two fractions mean
Anni [7]

Answer:

Multiplication

Step-by-step explanation:

I think what you're talking about is not a decimal, but a multiplication point:

\frac{1}{2} \:  . \:  \frac{3}{4}

This dot can donate multiplication when in the middle of two numbers and/or fractions.

But if you're talking about some other point, then I don't know, sorry. :(

What is the area of the squares with sides (2x-3)feet?​
LUCKY_DIMON [66]

Answer:

4x^2 -12x +9   ft^2

Step-by-step explanation:

The area of a square is

A = s^2 where s is the side length

A = (2x-3) ^2

A = (2x-3) (2x-3)

FOIL

first 2x*2x =4x^2

outer 2x (-3) = -6x

inner -3*2x = -6x

last -3*-3 = 9

Add them together

4x^2 -6x-6x +9

Combine like terms

4x^2 -12x +9

The area is 4x^2 -12x +9 ft^2

Solve with a system of equations: Two angles are supplementary if the sum of their measures are 180 degrees. If one is 90 degree
julsineya [31]

Answer:

  The measures of the angles are 150° and 30°.

Step-by-step explanation:

Let x and y represent the measures of the angles, with x representing the larger angle.

  x + y = 180 . . . . . . the two angles are supplementary

  x = 90 + 2y . . . . . one is 90° more than twice the other

___

Substituting the expression given by the second equation into the first, we have ...

  (90 +2y) +y = 180

  3y = 90 . . . . . . . . . . collect terms, subtract 90

  y = 30 . . . . . . . . . . . divide by the coefficient of y

  x = 180 -y = 150

The measures of the angles are 150° and 30°.
