Answer:
son = 4
mom=36
m = 9s
m + 4 = 5(s+4)
m + 4 = 5s + 20
9s + 4 = 5s + 20
4s = 16
s = 4
m = 36
Step-by-step explanation:
Remembering PEMDAS we solve like this
5•6=30 6÷2=3 30-3=27
27 is answer. it is easy, just replace the letter with the number and solve it
Answer:
y=-3/4x+4
Step-by-step explanation:
Equation Format:

where m = slope & c = y-intercept
Hence:
7=-3/4(-4)+c
7=3+c
c=4
y=-3/4x+4
Answer:
Step-by-step explanation:
6x+76x=5x-1
82x=5x-1
82x-5×=-1
77x=-1
X=-1/-77
X=1/77
