You'll do the (whole)(outside)= (whole)(outside) so, set it up like this: (5+3)3= (x+4)4now work it out with PEMDAS: 15+9=4x+16combine like terms: 24= 4x+16subtract the 16 from each side: 8=4xlastly, divide by 4 on each side to get x=2
got this from someone who answered this for me
Answer:
(3, 2), (2, 3)
Step-by-step explanation:
x + y = 5
xy = 6
Solve the first equation for x.
x = 5 - y
Substitute 5 - y for x in the second equation.
xy = 6
(5 - y)y = 6
5y - y² = 6
y² - 5y + 6 = 0
Factor.
(y - 2)(y - 3) = 0
y - 2 = 0 or y - 3 = 0
y = 2 or y = 3
Now substitute 2 for y in the first equation and solve for x.
x + y = 5
x + 2 = 5
x = 3
One solution is x = 3; y = 2, or (3, 2).
Now substitute 3 for y in the first equation and solve for x.
x + y = 5
x + 3 = 5
x = 2
Another solution is x = 2; y = 3, or (3, 2).

Answer:
Answer:
t=7(1.75c)
Step-by-step explanation:
If I assume that she does the same number of chores each day the equation is t=7(1.75c)
this is because c is the number of chores
and for each chore she earns 1.75 so then for each day it is 1.75c
there are 7 days in a week so you need to multiply that all by 7
so that is 7(1.75c)
that little equation finds the total amount earned so then it is
t=7(1.75c)
1.35/ 12 = 0,112 So the unit cost will be 0,112 Check the answer 0,112 *12 = 1.35
