Rufina [12.5K]

Answer:

400

Step-by-step explanation:

Method for rounding:

Look at the number 1 place before the place you are rounding to.

If it is greater than 4: round up

otherwise: round down.

Ok,

here the number we're looking at is 8 cuz' 8 is in the ones place.

8 is bigger than 4 so we round up.

Determine the missing side lengths​
svetlana [45]

Answer:

Given that is a 45-45 triangle, the hypotenuse should be <em>x</em>\sqrt{2}, so in this case. The hypotenuse should be 3\sqrt{2}, and the other side lengths 3. I see no other way of it going other than that one; I hope I helped at least a bit!

2x+3y=4
garri49 [273]

Answer:

Option D.

Step-by-step explanation:

we have

2x+3y=4 -----> equation A

2x-5y=-12  -----> equation B

Solve the system by elimination

Multiply both sides equation A by -1

-1(2x+3y)=-1(4)

-2x-3y=-4-----> equation C

Adds equation C and equation B

-2x-3y=-4\\2x-5y=-12\\------\\-3y-5y=-4-12\\-8y=-16\\y=2

<em>Find the value of x</em>

substitute the value of y in either equation

2x+3(2)=4\\2x+6=4\\2x=-2\\x=-1

The solution is the point (-1,2)

In this problem Option A,B and C are correct

The option D not result in a system with a pair of opposite terms

because

Multiply both sides of equation B by -3

-3(2x-5y)=-3(-12)

-6x+15y=36  -----> equation C

Multiply both sides of equation A by 55(2x+3y)=5(4)

10x+15y=20  ----> equation D

so

equation C and equation D not have a pair of opposite terms
