Let me try this

In order to solve this, we are going to use PEMDAS. If you have not heard of PEMDAS, it stands for parenthesis, exponents, multiplication, division, addition, subtraction. So, lets start with parenthesis. You would do parenthesis first. How do you do that? You just do the math in between the parenthesis. We would do exponents first. Its basically a number saying how much times to multiply the digit it is attached to. So, 3x3. We would then do subtraction, because multiplication, division nor addition is found next. 9-6 would be 3. Now, we would do multiplication next outside of the parenthesis. 3x4 = 12. Lets move on to division. 8 divided by 2 is 4. We would go to addition. 12+4 is 16. And lastly, subtraction. 16-5 is 11. The answer is 11.

Hope this helps.

I do not need an explanation, just a simple angle number!
Murljashka [212]

Answer:

Step-by-step explanation:

a + 143 = 180    {Linear pair}

a = 180 - 143

a = 37

37 + 93 + b = 180 {Angle sum property of triangle}

130 + b = 180

         b = 180 - 130

         b = 40

c + b = 90

c  + 40 = 90

c = 90 - 40

c = 50

d + 120 = 180   {Linear pair}

d = 180 - 120

d = 60

? = 60 + 40         {Exterior angle property of triangle}

? = 100

Solve the equation 3x-2y =7, x+2y= -3​
swat32

Answer:

  • x=1
  • y= -2

Step-by-step explanation:

  • 3x-2y =7
  • x+2y= -3
  • 4x=4
  • x=4/4
  • x=1
  • 3x-2y=7
  • 3(1)-2y=7
  • 3-2y=7
  • -2y=7-3
  • -2y=4
  • 2y=-4
  • y=-4/2
  • y= -2
  • Verify solution
  • x+2y= -3
  • 1+2y= -3
  • 2y=-3-1
  • 2y= -4
  • y= -4/2
  • y= -2
