Answer:
x=-3
Step-by-step explanation:
Answer:
Step-by-step explanation:
We can solve this system just by summing each side of the equation:
So, both left sides will be sum, and both right sides too.
The resulting expression will be:
Ordering and solving both sides:
Hence, the value to the system is
It's important to combine both equation, because the exercise is asking for the solution of the system.
Answer:
15 feets
Step-by-step explanation:
Perimeter of a rectangle = 2(l + w)
l = Length ; w = width
Perimeter, p = 48
Length of all sides
p = 2(l + w)
48 = 2(l + 9)
48 = 2l + 18
48 - 18 = 2l
30 = 2l
l = 30/2
l = 15
Length of the sides = 15 feets
Answer:
x = 1.2...
Step-by-step explanation:
Start with the given equation and isolate the variable.
6.2x + 1.2 = 8.9
Subtract 1.2 from each side:
6.2x = 7.7
Divide each side by 6.2:
x = 1.2...
Answer:
P = $7.00
Step-by-step explanation:
Movie tickets = $8.50
Drink = $4.75
Two friends also bought popcorn
Total spent by the group = $53.75
Given equation:
3(8.50 + 4.75) + 2p = 53.75
Where,
P = cost of one order of popcorn
3(8.50 + 4.75) + 2p = 53.75
25.50 + 14.25 + 2p = 53.75
39.75 + 2p = 53.75
2p = 53.75 - 39.75
2p = 14
p = 14 / 2
p = 7
p = $7.00
