Classify the system of equations.
x= -5 - y
2 + y = -x+3

intersecting
parallel
coincident​

Answers

Answer:Solve x=−5−y;2+y=−x+3

I will solve your system by substitution.

x=−y−5;y+2=−x+3

Step: Solvex=−y−5for x:

Step: Substitute−y−5forxiny+2=−x+3:

y+2=−x+3

y+2=−(−y−5)+3

y+2=y+8(Simplify both sides of the equation)

y+2+−y=y+8+−y(Add -y to both sides)

2=8

2+−2=8+−2(Add -2 to both sides)

Answer:

7x = 35cm ; 2x = 10cm

Step-by-step explanation:

7x and 2x are the lengths

7x+2x=45

Then you take 7 + 2 = 9

so is gonna be 9x = 45

then you divide both side with 9

so is gonna be x = 5

Then you take 5 multiply 7 : 2

so 7 x 5 = 35cm

2 x 5 = 10cm

Answer:

A=35, B=55, and C=25

Step-by-step explanation:

Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.

if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B

Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.

The solution of the given inequality

          x > 10

Step-by-step explanation:

Step(i):-

Given inequality  

                     3 ( x-8) > -4 + x

Multiply

                   3 x - 24 > -4 +x

subtract 'x' on both sides , we get

                 3 x - 24 - x > - 4 + x - x

        ⇒     2 x - 24 > - 4

Step(ii):-

Adding '2'4' on both sides , we get

        ⇒     2x - 24 + 24 > -4 +24

      ⇒     2 x > 20

Dividing '2' on both sides , we get

               [tex]\frac{2x}{2} > \frac{20}{2}[/tex]

                x > 10

Final answer:-

The solution of the given inequality

          x > 10

Answers

Answer:

34

Step-by-step explanation:

40 * .15= 6

40-6 = 34

okkk so you do 40 * .15 because you just put a decimal point before all percentages to convert it into number

40*.15= 6

then subtract 6 to the original amount

40-6=34

34 students went on the trip on thursday cause 6 students got killed by bears in the last trip.
