Answer:
the area is 110. the formula for a trapezoid is <em>A</em><em>=</em><em> </em><em>a</em><em>+</em><em>b</em><em>/</em><em>2</em><em> </em><em>×</em><em> </em><em>h</em><em>.</em><em> </em>
<em>A</em><em>=</em><em> </em><em>a</em><em>+</em><em>b</em><em>/</em><em>2</em><em> </em><em>×</em><em>h</em><em>=</em><em> </em><em>A</em><em>=</em><em> </em><em>9</em><em>+</em><em>1</em><em>3</em><em>/</em><em>2</em><em>×</em><em>1</em><em>0</em><em>=</em><em>1</em><em>1</em><em>0</em>

Answer:
(3, 4 )
Step-by-step explanation:
3x - y = 5 → (1)
x + y = 7 → (2)
adding the 2 equations term by term will eliminate y
4x + 0 = 12
4x = 12 ( divide both sides by 4 )
x = 3
substitute x = 3 into either of the 2 equations and solve for y
substituting into (2)
3 + y = 7 ( subtract 3 from both sides )
y = 4
solution is (3, 4 )

Answer:
No solutions
Step-by-step explanation:
Let's solve your system by elimination.
10x − 9y = −10
20x − 18y = −28
Multiply the first equation by -2, and multiply the second equation by 1.
−2(10x − 9y = −10)
1(20x − 18y = −28)
Becomes:
−20x + 18y = 20
20x − 18y = −28
Add these equations to eliminate x:
0 = −8
