Answer:
77 cm²
Step-by-step explanation:
We know that
Area of trapezium = ½ (a + b) × h
Area = ½ × (10 + 12) × 7
Area = ½ × 22 × 7
Area = 11 × 7
Area = 77 cm²

Answer:
x = 3 and y = -1
Step-by-step explanation:
It is given that,
3x + 2y = 7 ----(1)
2x - 5y = 11 ---(2)
<u>To find the solution of given equations</u>
eq(1) * 2 ⇒
6x + 4y = 14 ----(3)
eq(2) * 3 ⇒
6x - 15y = 33 ----(4)
eq(3) - eq(4) ⇒
6x + 4y = 14 ----(3)
<u>6x - 15y = 33 </u> ----(4)
19y = 19
y = -1
Substitute the value of y in eq (1) we get,
3x + 2y = 7 ----(1)
3x + (2 *-1) = 7
3x = 7 + 2 = 9
x = 9/3 = 3
Therefore x = 3 and y = -1
Answer:
14/15
Step-by-step explanation:
1 1/14
=> 14 x 1 + 1/14
=> 15/14
Reciprocal = Opposite
=> 15/14 reciprocal = 14/15
You just need to plug in the original price.
0.765(100)+0.06(.765(100)) = 81.09
The cost costs $81.09 for Chris.
