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

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The expression will be formed from the given data. Let the number be x so the expression will be:-

3x - 7 = 28

3x = 35

x = 35 / 3

x = 11.67

Therefore the number will be equal to 11.67.

A. (1.34)(5.46) = (1.76)(x)

Alja [10]

We are given an equation with an unknown variable x. We can find the value of x by dividing both sides by 1.76, as this will leave only x on the right hand side of the equation and its value on the left hand side, as shown below:

$(1.34)(5.46)=1.76(x) \\ \\ 
 \frac{(1.34)(5.46)}{1.76} = \frac{1.76(x)}{1.76} \\ \\ 
 \frac{(1.34)(5.46)}{1.76} =x \\ \\ 
4.16=x$

Thus solving the given equation, we get x =4.16, rounded of to nearest hundredth.
