Answer:
d=7-2/3f
Step-by-step explanation:
Move the variable to the right-hand side and change its sign- 3d=21-2f
Divide both sides of the equation by 3- d=7-2/3f
Write the solution d in parametric form- d=7-2/3f
Solution- d=7-2/3f
In math,
"of" is the same as "×" and "is" means "="
42.5% of x = 20.57
42.5% × x = 20.57
.425x = 20.57
x = 20.57/.425
x = 48.4
42.5% of 48.4 is 20.57
The value of n from the solution set is <u>3.</u>
<u>calculation:-</u>
⇒ 4n + 8 = 2
⇒ 4n = 20 - 8
= 4n = 12
= n = 12/4
⇒ n = <u>3</u>
Therefore, from the given set 3,8,10,12, the value of n will be 3.
A linear equation is an algebraic equation in which each term has an exponent of 1 or 0, and the graph of this equation is always a straight line. A measure of a metal's response to cold working. Cold working is the plastic deformation of metals below their recrystallization temperature and is used in many manufacturing processes such as wire drawing, forging, and rolling.
