Answer:
m∠3 = 70°
Step-by-step explanation:
By the properties of a parallelogram,
- Opposite angles of a parallelogram are equal in measure.
- Adjacent angles of a parallelogram are supplementary angles.
m∠2 = m∠4 and m∠1 = m∠3
4x + 30 = 2x + 70
4x - 2x = 70 - 30
2x = 40
x = 20
Therefore, m∠2 = m∠4 = 110°
Since, m∠2 + m∠3 = 180°
110° + m∠3 = 180°
m∠3 = 180° - 110°
m∠3 = 70°
Answer:
4xy-3x^2-9y^2
Step-by-step explanation:
-9x^2+4xy-8y^2+6x^2-y^2
simplify
4xy-3x^2-9y^2
Answer:240 strands of dough
Step-by-step explanation:
You make a loaf of challah bread by braiding 6 strands of dough together. This means
1 loaf of challah bread requires braiding 6 strands of dough together. This is the unit rate for making challah bread.
The number of loaves of bread you can make with 40 strands of dough will be
1 loaf of challah bread requires braiding 6 strands of dough
x loaves of challah bread will require braiding 40 strands of dough
x = 40 × 6 = 240 strands of dough
