Can someone please help me :((

By combining the equations they say

Step-by-step explanation:

-8x-5y=-13

-4x-5y= 11

so subtract  lower from the upper :)

  -8x-5y= -13

-(-4x-5y=11)

multiply by the negative sign

  -8x-5y= -13

+4x +5y= -11

now do the operations of each

-4x +0 = -24

hmm looks easier now , huh

x= - 24 / -4

x=  6

plug x in to either equations and solve for y

-8(6)-5y= -13

-48 -5y= -13

-5y=35

y = - 35 / 5

y = - 7     : )  yay !!

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
