Well we know the sum of all the angles on a triangle is 180.
And we already know 2 of the sides: 102 and 31. So add them up and subtract it from 180.
102 + 31 = 133.
180 - 133 = 47.
So "x" is 47.
Answer:
Step-by-step explanation:
Hi! I dont know if i did this how your teacher wanted you to, but this is what i did:
36 divided by 6 is 6 - 36 ÷ 6
So, the answer for Igor is 6
So, because 6 is in one pack, 6 times 3 is 18 - 6 x 3
So, the answer for Elsa is 18.
I hope this helped!!
Have a good day :)
First let's multiply the 2nd equation by 2 so:
Now we will eliminate the x variable by subtracting equation 2 from equation 1.
Now plug in your y value into any of the 2 equations, let's use the 1st equation:
2x+3(8)=4
2x+24=4
2x=-20
x=-10
and so the solution is (-10,8)
