The given expression is a (A) linear expression.
<h3>
What are linear expressions?</h3>
- A linear expression is an algebraic expression in which each term is a constant or a variable raised to the first power.
- To put it another way, none of the exponents may be greater than 1. x2 is a variable raised to the second power, whereas x is a variable raised to the first power.
- A constant is represented by the number 5.
- Reduce the equation as much as feasible to the form y = mx + b. Examine your equation for exponents.
- It is nonlinear if it has exponents. Your equation is linear if it contains no exponents.
- 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x - y + z = 3 are some instances of linear equations.
Therefore, the given expression is a (A) linear expression.

Answer:
7 + (x/2) = 9.2
solve for x.
Step-by-step explanation:
We're hanging weights from a spring and measuring the distance of stretch. This is how those vegetable scales in grocery stores work (kind of). We know that the spring, with no weight, is 7 cm. So it can't get any shorter than this. We also know that for every kg of mass added, the spring stretches 0.5 cm. So, if you hung 3 kg of weight, the spring would have to stretch 0.5 * 3 = 1.5 cm. Add to that the 7 cm that it was originally and we have 8.5 cm of total length.
The second question is essentially answered by the first because the blank equation given in the first says
(initial length) + 1/2 * (mass added) = (total length)
The initial length will be a constant 7, the mass added we're told is to be x and the total length is to be y. Put those in their places and graph accordingly.
3) This is simply asking you to do what you've been doing, but in reverse. We have an equation, so we can now just plug in what we know and solve for what we don't.
7 + (x/2) = y
y = 9.2 in this case because it's representative of the total length, so we have
7 + (x/2) = 9.2
Now just solve for x.
$1,200=to repair his home
21%=interest
$121=every month
12=month
21. X
——= ———-
100. 1200
Cross multiply
21*1200=25200
100*x=100x
25200/100=252
So Loki paid $252 interest
<span>The answer is A because the die rolled first time can in no way affect the outcome of the second roll of the die, so both the events are independent events which do not affect each other.</span>
