Answer:
1/3
Step-by-step explanation:
2/5+2/5-7/15
=2+2/5 -7/15
=4/5-7/15
=4×3-7/15
=12-7/15
=5/15
=1/3 Ans.
11a.
12a-1a=11a is same thing as 12a-a
Answer:
Step-by-step explanation:
Area of Parallelogram = Base * Height
Where base = 3.7 cm, Height = 7.6 cm
=> Area = 3.7 * 7.6
=> Area = 28.12 cm^2
Answer:
The answer to your question is 1.- (37/2, -9/2) 2.- g = 4 and h = 2
Step-by-step explanation:
Data
Equation 1 2x + 8y = 1
Equation 2 x = -3y + 5
Process
1.- Substitute equation 2 in equation 1
2(-3y + 5) + 8y = 1
Expand
-6y + 10 + 8y = 1
Solve for y
8y - 6y = 1 - 10
2y = -9
y = -9/2
2.- Substitute y in equation 2 to find x
x = -3(-9/2) + 5
Simplify
x = 27/2 + 5
x = 27/2 + 10/2
x = 37/2
Solution (37/2, -9/2)
2.-
Equation 1 6g + 8h = 40
Equation 2 -6g + 2h = -20
Process
1.- Add both equations
Result
0 + 10h = 20
Solve for h
h = 20/10
h = 2
2.- Substitute h in Equation 1 to find g
6g + 8(2) = 40
Simplification
6g + 16 = 40
Solve for g
6g = 40 - 16
6g = 24
g = 24/6
g = 4
Solution g = 4 and h = 2
