Answer:

It’s easier to find the solution to a variable when that variable is by itself on one side of the equal sign. Rearranging formulas before substituting values for each variable makes calculations more straightforward. With this approach, we only need to perform operations such as multiplication, division, addition, and subtraction on one side of the equal sign, and we simplify instead of solving by using the properties of equality.

Step-by-step explanation:

(04.05)Marisa painted 1 of her bedroom in 3 of an hour. At this rate, how long would it take her to paint the entire room?
tensa zangetsu [6.8K]

The Question above is incomplete.

Complete Question

Marisa painted one-half of her bedroom in three-fourths of an hour. At this rate, how long would it take her to paint the entire room? three-eighths of an hour eight-thirds of an hour four-sixths of an hour six-fourths of an hour

Answer:

six-fourths of an hour

Step-by-step explanation:

Let her entire room be equal to 1

From the above question

1/2 of her bedroom = 3/4 of an hour

1(Entire bedroom) = x hour

Cross Multiply

1/2 × x = 3/4 × 1

x = 3/4 / 1/2

x = 3/4 ÷ 1/2

x = 3/4 × 2/1

x = 6/4 hour

Hence, it would take Marissa six-fourths(6/4) of an hour to clean her entire room.

Hello can someone please help me on this :)
Zielflug [23.3K]

Answer:

Step-by-step explanation:

1.

Find value of P that makes this true

4p-5=`9

Solve for P by isolating it on one side:

4p-5+5=9+5

4p/4=14/4

P=3.5

2.

Translate the Algebraic Expression:

A waiter earns $128 for 6 hours of work including $86 of tips.

Subtract tips from total:

128-86=42

Divide Value between hours.

42/6=7

$7 per hour

3.

Find the Value of X that makes this true

-4x+26=-2

Solve for X by isolating it on one side:

-4x+26-26=-2-26

-4x/-4=-28/-4

X=7

4.

What is the first correct step in solving the equation:

33-2x=31

Subtract 33 from both sides
