move the constant to the right change its sign
n= -16 - 4
calculate the difference
N= - 20
Answer:
[tex]n=-20[/tex]
Step-by-step explanation:
1) Subtract 2 from both sides.
[tex]\frac{n}{2} =-8-2[/tex]
2) Simplify −8−2 to −10.
[tex]\frac{n}{2} =-10[/tex]
3) Multiply both sides by 2.
[tex]n=-10*2[/tex]
4) Simplify 10 * 2 to 20.
[tex]n=-20[/tex]
Therefor, the answer is n = - 20.

a hikers map has a scale of 3 inches to 10 miles. the trail is 4 inches long on the map. how long is the actual hike?
Answer:
13 1/3 miles
Step-by-step explanation:
inches/miles = inches/miles
3/10 = 4/x
3x = 40
x = 13 1/3
Unit conversion is the conversion of one unit to another unit with its standard conversion.
3 inches = 10 miles
4 inches = 13.33 miles
The actual length of the trial is 13.33 miles.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
1 m = 100 cm
We have,
Scale factor:
3 inches = 10 miles
Map:
Length of the trial = 4 inches
The actual length of the trail.
3 inches = 10 miles
Multiply both sides by 4/3.
4/3 x 3 inches = 4/3 x 10 miles
4 inches = 13.33 miles
Thus,
The actual length of the trial is 13.3 miles

A farmers field has the dimensions 2 and 3/4 by 1 and 1/3. He needs to find the area of the field
Answer:
3 2/3 units²
Step-by-step explanation:
Since the field is rectangular in nature;
Area of the field = Length * Width
Given
Length = 2 3/4
Width = 1 1/3
Area of the field = 2 3/4 * 1 1/3
Area of the field = 11/4 * 4/3
Area of the field = 4/4 * 11/3
Area of the field = 1 * 11/3
Area of the field = 11/3
Area of the field = 3 2/3
Hence the area of the field is 3 2/3 units²

Which quadratic relation has a y-intercept of 8?
O y = 0.5(x + 2)(x + 4)
O y = 0.5 (x - 2)(+ 8)
O y = 0.5(x2 -2x - 16)
O y = 0.5 (x2 -2x + 16)
Answer:
y = 0.5 (x^2 -2x + 16) has a y-intercept of 8.
Step-by-step explanation:
The x-coordinate of every y-intercept is zero. To determine which of the four quadratics given here has a y-intercept of 8, we need only substitute 0 for x in each; if the result is 8, we've found the desired quadratic.
O y = 0.5(x + 2)(x + 4) becomes y = 0.5(2)(4) = 4 (reject this answer)
O y = 0.5 (x - 2)(x + 8) becomes y = 0.5(-2)(8) = -8 (reject)
O y = 0.5(x2 -2x - 16) becomes y = 0.5(-16) = -8 (reject)
O y = 0.5 (x2 -2x + 16) becomes y = 0.5(16) = 8 This is correct; that '8' represents the y-intercept (0, 8).
Which equation represents a line which is perpendicular to the line x – 2y = 2?
Answer:
Step-by-step explanation:
x-2y=2
2y=x-2
y=(x-2)/2
so the slope is 1/2
for lines to be perpendicular m1m2=-1 so the line must have a slope satisfying the condition
(1/2)m=-1
m=-2
the only line with a slope of -2 is
y=-2x+5
The equation represents a line that is perpendicular to the line x – 2y = 2 would have a slope of -2. The equation would be y = -2x + 5.
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
The given equation of line is
x-2y=2
2y = x - 2
y = (x - 2)/2
so, the slope of the equation is 1/2.
For the perpendicular lines
[tex]m_1m_2=-1[/tex]
So the line must have a slope that satisfies the condition.
(1/2) m = -1
m = -2
Hence, the only line with a slope of -2 is y = -2x + 5.
