Hello,
Here is the formula to find the area of the trapezoid:
A=1/2(b1+b2)×h
Where b1 represent big base
b2 represent small base
and h represent height
Now, we just need to replace the number to get the final answer:
A=1/2(16.8+6.9)×2
A=1/2(23.7)×2
A=23.7 square yards. As a result, the area of the trapezoid is 23.7 square yards. Hope it help!
Answer:
(-1, -2)
Step-by-step explanation:
4x - 7y = 10
3x + 2y = -7
The common multiple of the x coefficient is 12.
Multiple 3 to 4 to get 12; 4 to 3 to 12:
3(4x - 7y = 10)
4(3x + 2y = -7)
12x - 21y = 30
12x + 8y = -28
Subtract the two equations:
-29y = 58
y = -2
Substitute y = -2 to either 4x - 7y = 10 or 3x + 2y = -7. Typically, do the easier equation to solve:
3x + 2(-2) = -7
3x - 4 = -7
3x = -3
x = -1
The order pair solution is like a coordinate: (x, y)
You are welcome!

Answer:
Step-by-step explanation:
m + j + s = 37
j = 2s......s = j/2 or 1/2j
m = j + 2
(j + 2) + j + (1/2j) = 37
2j + 1/2j = 37 - 2
2j + 1/2j = 35....multiply everything by 2 to get rid of the fraction
4j + j = 70
5j = 70
j = 70/5
j = 14 < ==== Jan is 14
m = j + 2
m = 14 + 2
m = 16 <==== marcia is 16
s = 1/2j
s = 1/2(14)
s = 14/2
s = 7 <==== sydney is 7
