Answer: A
Step-by-step explanation:
Answer:
x=34, y=-28, z=-46
Step-by-step explanation:
because opposite angles of parallelograms are congruent: -3y-3=81 => y=-28. because internal angles of quadrilateral sum to 360°: 81+-3(-28)-3+3x-3-2z+7=360 => 3x-2z=194 => z=3/2x-97. because opposite angles of parallelograms are congruent: -2z+7=3x-3. substitute z=3/2x-97: -2(3/2x-97)+7=3x-3 => x=34. z=3/2(34)-97=-46
Area=(base x height)/2
base=5.8 cm
height=2.4 cm
Area=(5.8 cm * 2.4 cm) / 2=6.96 cm²
The answer is A 6.96
Answer:
1.Solve for y in 2x+y=-3
y=-3-2x
2. Substitute y= -3 - 2x into 4x-2y=10
8x+6=10
3 Solve for x in 8x+6=10
x=1/2
4. Substitute x=1/2 into y = - 3 - 2x
y= -4
5. So you get...,
x=1/2
y=−4
