Answer:

x = 13

Step-by-step explanation:

you first must set them equal to each other

( 4x + 7 ) = [5(x-4)]

Then you distribute 5 to (x-4)

you then get (5x-20)

so now in all you have 4x-7 = 5x-20

you then move the 4x by subtracting form both sides

-7 = x-20 is what is left

now add 20 to both sides

your answer is x = 13

Erin created a scale drawing for a garden that will be 10 ft by 5 ft. She plans to include a section in the garden for herbs, wh
Elanso [62]

Answer:

The dimensions of the herb garden in the scale drawing are 2.4 in. by 6 in

Step-by-step explanation:

we know that

The dimensions of the garden in the actual are 10 ft by 5 ft

The dimensions of the garden on the scale drawing are 12 in. by 6 in

step 1

Find the scale factor

To find the scale factor divide the corresponding side on the scale drawing by the corresponding side in the actual

so

\frac{12}{10}\ \frac{in}{ft}

simplify

1.2\ \frac{in}{ft}

That means

1.2 inches in the drawing represent 1 foot in the actual

step 2

Find out  the dimensions of the herb garden on the scale drawing

we know that

The dimensions of the herb garden in the actual are 2 ft by 5 ft

Multiply by the scale factor

so

2\ ft=2(1.2)=2.4\ in

5\ ft=5(1.2)=6\ in

therefore

The dimensions of the herb garden in the scale drawing are 2.4 in. by 6 in

42/50 in simplest form
gulaghasi [49]
To find the simpliest form of a fraction, all you need to do is divide the numerator and denominator by their greatest common factor, in which in this case, is 2. And so all you need to do is divide the numerator(42) and the denominator(50) by 2, to get 21/25. This means that the simpliest form of 42/50 is 21/25.
