An expression is defined as a set of numbers, variables, and mathematical operations.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The expression that is equivalent to 2.3p – 10.1 = 6.5p – 4 – 0.01p are given below,

If the given expression 2.3p – 10.1 = 6.5p – 4 – 0.01 is simplified, then the expression can be written as,

2.3p – 10.1 = 6.5p – 4 – 0.01

2.3p – 10.1 = 6.49p – 4

Thus, Option A is one of the option.

Using the multiplication property of Equality, if we multiply both the sides of the equation by 100, then we will get,

230p – 1010 = 650p – 400 – p

Thus, c is one of the option.

Hence, the correct options are A and C.

Helena creates two similar rectangles using exactly 100 cm of string. The smaller rectangles width and length are 4 cm by 6 cm r

Misha Larkins [42]

Answer:

The dimensions of the larger rectangle are $24\ cm$ of length by $16\ cm$ of width

Step-by-step explanation:

Let

x-----> the length of the larger rectangle

y-----> the width of the larger rectangle

we know that

$\frac{x}{y}=\frac{6}{4}$ ------> by similar rectangles

$x=1.5y$ -----> equation A

<u>Find the perimeter of the smaller rectangle</u>

$P=2(6+4)=20\ cm$

<u>Find the perimeter of the larger rectangle</u>

Subtract the perimeter of the smaller rectangle from 100 cm of string

$P=100-20=80\ cm$

Remember that

$80=2x+2y$ ------> $40=x+y$ ------> equation B

substitute equation A in equation B

$40=1.5y+y$

$2.5y=40$

$y=16\ cm$

Find the value of x

$x=1.5(16)=24\ cm$

The dimensions of the larger rectangle are $24\ cm$ of length by $16\ cm$ of width
