Answer:

x=-1

y=-6

Step-by-step explanation:

To solve for x and y in 2x+3y=-20 start by substituting y for 6x

2x+3(6x)=-20 simplify the left side by multiplying 3 and 6x then add the product to 2x

20x=-20 now divide 20 on both sides

x=-1

now that you know what x is, you can solve for y

2x+3y=-20 substitute x for -1

2(-1)+3y=-20 now simplify by multiplying 2 and -1

-2+3y=-20 add -2 on both sides

3y=-18 now divide 3 on both sides

y=-6

Answer:

(-1,-6)

Step-by-step explanation:

Plug 6x for y into the bottom equation:

2x+3(6x)= -20

2x+18x= -20

20= -20

x= -1

Substitute -1 for x in the equation for y:

y=6(-1)

y=-6

I hope I could help :)

Jake drew an isosceles right triangle. What are the measures of the two acute angles? How do you know?
scoray [572]
SO you know that triangles add up to 180. A right angle equals 90 so 180-90=90. And an isosceles triangle means that 2 angles are congruent. SO 90/2 = 45. The measure of the 2 acute angles are 45

The sum of three consecutive integers is 168. What are the integers
Tema [17]

Answer:

3X + 3 = 168

3X + 3 - 3 = 168 - 3

3X = 165

3X/3 = 165/3

X = 55

Step-by-step explanation:

We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 168. Therefore, you can write the equation as follows: (X) + (X + 1) + (X + 2) = 168
