Answer:
And is an inclusive conjunction, meaning more can follow and exist at the same time, while or is an exclusive conjunction, meaning only one choice can exist at one time.
Step-by-step explanation:
Answer:
1997 lbs
Step-by-step explanation:
First we need to find the volume of the mattress
V = l*w*h
V = 8*2*2
V =32 ft^3
Then multiply by the density
32 ft^3 * 62.4 lb / ft^3 =
1996.8 lbs
To the nearest lb
1997 lbs
For systems of equations try using graphing, substitution, and elimination. For example
{2x+7y=3}
{x=-4y}
You should first look at if you have a variable that can be substituted (using substitution) and in this case we do! you plug in the x into 2x meaning 2(-4y)+7y=3
1) distribute -8y+7y=3
2) combine like terms in this case -8y+7y= -1y
3) solve -1y=3
y=-3
so currently our solution is (0,-3)
now we solve for x.
we plug our solved variable (y) into 7y
7(-3) and our equation looks like this
2x+7(-3)=3
1) distribute 7(-3)=-21
2) rewrite then solve 2x+(-21)=3
3) isolate variable -21+21 & 3+21
4) 2x=24
5) solve 2/24 = 12
Meaning our solution is (12,-3)
This is how to solve by substitution.
Answer:
Option (4)
Step-by-step explanation:
If ΔLMN is similar to ΔQRS,
Their corresponding sides will be proportional.
But it's not true.
Therefore, the given triangles ΔLMN and ΔQRS are not similar.
Option (4) will be the answer.
