-7x - 2y = 19
4x + y = -12
Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)
-7x - 2y = 19
8x + 2y = -76
Add equations together
x = -52
Plug x value into an equation
4(-52) + y = -12
Solve for y
-208 + y = -12
y = 196

Hello from MrBillDoesMath!
Answer:
27
Discussion:
By the distance formula (or Pythagorean theorem)
distance = sqrt ( (change in x)^2 + (change in y)^2)
In our case this becomes
distance = sqrt ( (18 - (-9) )^2 + (-12 - ( -12))^2)
= sqrt ( ( 18 + 9) ^2 + ( -12 + 12) ^ 2)
= sqrt ( ( 18 + 9) ^2 + 0^2 )
= sqrt ( 27^2)
= 27
Geometrically, as both y coordinates = -12, the points define a horizontal line segment. The length is then simply the difference of the x coordinates, 18 - (-9) = 18 +9 = 27. Same answer as before
Thank you,
MrB
Answer:
each package of Milk Chocolate M&M's should contain 24% blue, 14% brown, 16% green, 20% orange, 13% red, and 14% yellow M&M's.
For the rectangle: l x w = Area
l = 18
w = 18
18 x 18 = 324
If 16m is for dash line
1/2bh
1/2(16)(16)
4(16) = 64
1/2bh
1/2(8)16
8(8) = 64
324 + 64 + 64 = 452
Your area should be 452m²
hope this helps
