Step-by-step explanation:
Hi,
3(x + 5) = -4x + 8
3x + 15 = -4x + 8

7x = -7
x = -1
One solution :)
Substract 6 to both sides and you get 36 =-2d then you use the multiplicative inverse and d=-18.
Answer:
Mom=30 Daughter=6
Step-by-step explanation:
M=5×D
M+6=3×D
5D=3D-6
2D=6
D=12
M=12×3=36
Now: D=12-6=6
M=36-6=30
The median would be: 7.9
and the mean would be:7.4714285714 (you are able to chop that down a bit if needed)
