So I'll walk through the first 2. Then please try the other ones and let me know if you run into more problems.
5m-6
If m is equal to 7, then replace m with 7.
5(7)-6
5x7=35 so the expression is now 35-6. Solve.
35-6=29
So that was the first one.
4m+t
We just do what we do with the first problem.
4(7)+(2)
4x7=28 so the expression is 28+2.
28+2=28

hope it helps
p.s. When there is subtraction, add. When there is division, multiply to cancel that out. When there is multiplication, divide to cancel. etc.
Answer:
48x+13.8
Step-by-step explanation:
i think you stack them and cross multiply.
Base = 5 * 12 = 60 in^2
Height = 4 in
Perimeter is the sum of all straight
Perimeter = 20 + 16 + 48
Perimeter = 84 in
Perimeter of base = 12 * 2 + 5 * 2 = 34
Answer:
$160.75
Step-by-step explanation:
Step one:
given data
The resort charges $20.75 per hour in addition to a $35 deposit to rent a snowboard
The time spent from 8:30 am to 12:30 pm = 4hours
Step two:
Let the number of hours be and the total cost be y
Now the expression for the situation can be represented as
y= 20.75+35x
for x= 4
y=20.75+35(4)
y=20.75+140
y=160.75
