Answer:
7n-25 < -39
Step-by-step explanation:
Answer:
15 and 1
Step-by-step explanation:
x and y are two numbers.
Two equations:
x · y = 15
x + y = 16
Rearrange one of the equations (I'll rearrange the sum equation):
x + y = 16
x = 16 - y
Substitute that to the other equation and solve for y:
x · y = 15
(16 - y) · y = 15
16 - y · y = 15
16 - y² = 15
-y² = 15 - 16
-y² = -1
y² = 1
y = √1
y = 1
Now substitute that to any of the equation and solve for x (in here, I'll choose the multiplication one):
x · y = 15
x · 1 = 15
x = 15
Now verify:
15 · 1 = 15
15 + 1 = 16
This is correct
In parallelogram SAVE, the value of the angle is m∠SEV = 125° while in parallelogram MORE ∠MOR = 111
<h3>What is a
parallelogram?</h3>
A parallelogram is a quadrilateral with equal opposite and parallel sides. Opposite angles are equal.
In parallelogram SAVE:
m∠VAS = m∠SEV
3x - 5 = 2x + 15
x = 20
m∠VAS = 3(20) - 5 = 55 degrees
m∠VAS + m∠SEV = 180 (consecutive interior angles)
55 + m∠SEV = 180
m∠SEV = 125°
In parallelogram MORE:
∠MOR + ∠ORE = 180 (consecutive interior angles)
4x - 5 + 2x + 11 = 180
x = 29
∠MOR = 4(29) - 5 = 111
In parallelogram SAVE, the value of the angle is m∠SEV = 125° while in parallelogram MORE ∠MOR = 111
