A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of

the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:
Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).

A = x(x − 4) + 0.5(6)(x − 4) + 2(7)
A = x(x − 4) − 0.5(6)(x − 4) − 2(7)
A = x(x − 4) − (6)(x − 4) − 2(7)
A = x(x − 4) + (6)(x − 4) + 2(7)

Solve<br>7w - 5 &lt; 1 - 3w<br>can someone help me ?​
Darina [25.2K]

Answer:

w < 0.6

Step-by-step explanation:

In this problem, one is given an algebraic inequality. These types of inequalities can be solved using similar methods that one uses to solve an algebraic expression, in essence, one uses inverse operations. The only major difference between solving algebraic inequalities and algebraic expressions is that when one divides or multiplies by a negative number, one must remember to flip in the inequality sign to maintain the trueness of the equation. In this case, such a rule will not come into play.

7w - 5 < 1 - 3w

Inverse operations,

7w - 5 < 1 - 3w

+3w          +3w

10w - 5 < 1

     +5    +5

10w < 6

/10     /10

w < 0.6

7 and 1/4 divided by 5/6 as a fraction or mixed number in simplest form
Alchen [17]
First off, turn 7 1/4 into a mixed number, 29/4. change 29/4  /  5/6   into a multiplication question by flipping 5/6 into 6/5 (AKA multiplying by the reciprocal) so you get 29/4  X  6/5. then multiply so you get 174/20. Next, simplify into a mixed number by seeing how many times 20 goes into 174, and then putting the leftovers into a fraction, so you get 8 14/20, then simplify even further so you get 8 7/10.
