Answer: The value of x = 5.
Step-by-step explanation:
Given linear equation is 12-x=7 with variable x
To find the solution i.e. the value of x of the given linear equation, we need to perform following steps:
Step 1. Subtracting 12 from the both sides of the equation,we get
⇒12-x-12=7-12
⇒-x=-5
Step 2. Multiplying (-1) on the both sides ,we get
⇒-x × -1=-5 × -1
⇒x=5
So ,the value of x=5
Thus required solution of the given linear equation is x=5.
12-x=7. Well if you look at seven you should Be able to subtract 7 from 12 and get five.
You x Value = 5!
The inequality that represents the number of toll passes without having to add any value to the toll pass is 18.
It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Toll pass accountvalue = $32
Amount deducted with each toll pass = $1.25
The amount in the account after which value is added to the account.
= below $10
The inequality that represents the number of toll passes.
32 - 1.25x < 10
Solve for x.
32 - 1.25x < 10
32 - 10 < 1.25x
22 < 1.25x
1.25x > 22
x > 22/1.25
x > 17.6
Thus,
The number of tollpasses is 18.

Triangles ABC and DEF are similar, which means corresponding sides are proportional to one another. Here, side AB corresponds to DE, BC to EF, and AC to DF.
We know the length of AB and AC, and we can figure out the length of BC using the Pythagorean theorem:
Sides BC and EF correspond to one another, and EF is 2 times longer than BC. This means DF is 2 times longer than 17, so that .
