Answer:
5
Step-by-step explanation:
10-(2+3) = 5
Alright, lets get started.
Suppose the original square window has the side = x feet
The new window is 3 ft wider and 2 ft higher than the square one.
Means length of the new window will be = 
Width of the new window will be = 
So the area of the new window will be = 
So the area of the new window will be = 
So the area of the new window will be = 
As given in question the area of 30 square feet for the new window, hence


Factoring

x = -8 or x = 3
Side could not be negative hence
side of the original square window will be = 3 feet : Answer
Hope it will help :)
Answer:
0.028 Gallons/mile
Step-by-step explanation:
1 Gallon = 3.78541 Litres
1 Mile = 1.60934 Km
Total Fuel Expenditure (Dec 2019) = PKR 7,000
Fuel cost / Litre = 114Litre/Km
Total Fuel consumption = (7000/114)
= 61.40 Litres or 16.22 Gallons
Total Distance Travelled in Dec 2019 = 921 Km or 572.28 miles
Fuel Economy = 16.22/572.28
= 0.028 Gallons/mile
One time tank fill up cost = PKR 1,500
Answer:
1) The solution to the given equations is (3,6)
2) The solution to the given equations is (7,-1)
3) The solution to the given equations is (6,5)
Step-by-step explanation:
1) Given equations are 
and 
To solve the given equations by substitution method :
From equation (2) we have the value x=1+y
Substitute the value of x=1+y in equation (1) we get
(1+y)+y=5
1+y+y=5
1+2y=5
2y=5-1
2y=4

Therefore y=2
Now substitute the value of y=2 in equation (2) we get
x=1+y
x=1+2
Therefore x=3
The solution is (3,6)
2) Given equations are 
and 
To solve the given equations by substitution method :
From equation (2) we have the value x=6-y
Substitute the value of x=6-y in equation (1) we get
2(6-y)+3y=11
12-2y+3y=11
y=11-12
Therefore y=-1
Now substitute the value of y=-1 in equation (2) we get
x+(-1)=6
x=6+1
Therefore x=7
The solution is (7,-1)
3) Given equations are 
and 
To solve the given equations by substitution method :
From equation (1) we have the value x=1+y
Substitute the value of x=1+y in equation (2) we get
6(1+y)-7y=1
6+6y-7y=1
-y=1-6
Therefore y=5
Now substitute the value of y=5 in equation (1) we get
x-5=1
x=1+5
Therefore x=6
The solution is (6,5)
The equation is positive, so the graph should be on the other side. One way to check this would be to plug a number in the equation,
where x = -2
y= 3/2(-2)-1
y= -3-1
y= -4
on the graph you plotted you have y = 2 where x = -2
