Answer:
The SI unit for length is the meter (abbreviated m); its definition has also changed over time to become more accurate and precise. The meter was first defined in 1791 as 1/10,000,000 of the distance from the equator to the North Pole.
Answer:
D
Step-by-step explanation:
out of the choices
A) 2x-y=-2
3x+2y=-10
B) x+4y=3
2x+5y=3
C) 2x+3y=5
x-4y=-14
D) 3x+4y=15
x+y=5
only the system in D has a solution of x=5 and y=0
solve by substitution x+y=5 so x=5-y
plug into the other equation so 3(5-y)+4y=15
distribute 15-3y+4y=15 then minus 15 on both sides and combine like terms
so y=0 then put that value back into the other equation
so x+y=5 equals x+0=5 so x=5 this means the solution to the system of equations is the point (5,0)
Hope this helps! :)
Answer:
16 - 2 = 14
Step-by-step explanation:
The lines mean absolute value and the absolute value of -16 is and of -2 is 2
So an example
least common multipule is like what is
the smallest number both will fit into
example, 6 and 10, least common
multilule is 30 because 6*5=30 and 3*10=30
so 3 and 4
factor each
3=3
4=2*2
so we have to have 2*2*3 which is 12
12 is least common multiplule
