Wow that's too much work!!! is this a table or printout?
Answer:
120/3 = 40 40x2 =80 120-80=40 the answer is 40 pages
Step-by-step explanation:
Answer:
J= 40+13t
I= 80+9t
they are equal at 10 weeks
Step-by-step explanation:
So we can start this by writing our equations
J= 40+13t
I=80+9t
To figure out when they're equal set the two equations equal to each other and solve for t
40+13t=80+9t
subtract 40 and 9t from both sides to get
40=4t
divide by 4 and get
t=10
I would use subsitution because both are already equal to a single variable
set both equal since both equal y
8x-9=y=4x-1
8x-9=4x-1
minus 4x both sides
4x-9=-1
add 9 boh sides
4x=10
divide by 4
x=10/4=5/2
sub for x
y=4x-1
y=4(10/4)-1
y=10-1
y=9
(5/2,9) is solution
A. work shown above
B. (5/2,9) or (2.5,9)
