C. a quantity used as a standard measurement
Step-by-step explanation:
A unit is a universally acceptable system of measurement. The system is majorly referred to as the international standard of units i.e (SI) units.
Since physical quantities could be categorize as either fundamental or derived. The use of units in measurement is very essential, because it relates the magnitude measured to the physical quantity.
The units of measurement tells what physical quantity has been measured.
Answer:
y=1 , z=-2
Step-by-step explanation:
I will use the method of elimination :
Multiply the top equation by 5 to make equation 3 :
35z + 15y = -55
Multiply bottom equation by 3 to make equation 4:
6z + 15y = 3
Subtract equation 3 from equation 4 to eliminate the y :
-29z = 58
Divide both sides by -29 to solve for z :
z = 58 ÷ -29
z = -2
Substitute this value into either equation 1 or 2 to solve for y :
I chose equation 2 :
2(-2) + 5y = 1
-4 + 5y = 1
Add 4 to both sides :
5y = 5
Divide both sides by 5 :
y = 1
Hope this helped and have a good day
it is 1/6 that is the anwser
Answer:
Step-by-step explanation:
we would like to factor the following:
let a²+b²=x
thus substitute:
rewrite the middle term as 4x-22x:
factor out x:
