Answer:

The first one would be 3/5, the top one in the second branch would be 1/5 and the bottom one would be 3/5. You get to this answer by subtracting 1-(the fraction you already have).

omeli [17]

<span>x = length cm
y = width cm
---
y = 3
xy = area
xy = 1035
x*3 = 1035
x = 1035/3
x = 345

so the answer is 345</span>

2. The width of a rectangle is 5 units less than the length. If the area is 150 square units, then find the dimensions of the re

xz_007 [3.2K]

Answer:

The length = x = 15 units

The width = x-5 = 10 units

Step-by-step explanation:

Let 'x' be the length of a rectangle

As the width of a rectangle is 5 units less than the length.

width of rectangle will be = w = x - 5 units

Area = 150 square units

Using the formula

Area = length × width

$150=\left(x\right)\left(x-5\right)$

$150=x^2-5x$

$x^2-5x=150$

Subtract 50 from both sides

$x^2-5x-150=150-150$

$x^2-5x-150=0$

$\left(x+10\right)\left(x-15\right)=0$

$ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)$

$x+10=0\quad \mathrm{or}\quad \:x-15=0$

$x=-10,\:x=15$

As length can not be negative. so

x = 15 units

Hence,

The length = x = 15 units

The width = x-5 = 15-5 = 10 units

(2 tens 1 one)x10 in unit form and standard form

omeli [17]

When the number expression given as (2tens 1 one) x 10 is written in standard form, the standard form is 210 and the unit form is 2 hundred, and 1 ten

<h3>How to write the number in standard form?</h3>

The number expression is given as:

(2tens 1 one) x 10

2 tens is represented as:

2 * 10

1 one is represented as:

1 * 1

So, the number expression can be rewritten as:

(2tens 1 one) x 10 = (2 * 10 + 1 * 1) x 10

Evaluate the product

(2tens 1 one) x 10 = (20 + 1) x 10

Evaluate the sum

(2tens 1 one) x 10 = (21) x 10

Evaluate the product

(2tens 1 one) x 10 = 210

When the number expression given as (2tens 1 one) x 10 is written in standard form, the standard form is 210 and the unit form is 2 hundred, and 1 ten

Using the above steps as a guide, we have:

(5 hundreds 5 tens) * 10 ⇒ 5 thousands and 5 hundreds ⇒ 5500
(2 thousands 7 tens) / 10 ⇒ 2 hundreds and 7 units ⇒ 207
(4 ten thousands 8 hundred) / 10 ⇒ 4 thousands and 8 tens ⇒ 4080
