Answer:
B
Step-by-step explanation:
6n - 2(4n + 7) + 4= -2 firstly you open the bracket
6n - 8n - 14 + 2 = -2 then you collect the like terms
6n - 8n= -2 + 14 - 4 then add and subtract and divide by the coefficient
-2n= 12 - 4
-2n = 8
= n = 8 ÷ -2
n = -4
Hank's speedometer reads 60 miles per hour, but during a road test he finds that he was actually driving 50 miles per hour. What is the percent error in Hank's speedometer?

Explanation: 20% of 50 which is the miles per hour he actually drove is 10 and 50 + 10 = 60 which is the incorrect miles per hour his speedometer read.

Side AB =
Angle E =
Answer:
4
30 deg
Step-by-step explanation:
AD/EH = 6/1.5 = 4
Each side in ABCD is 4 times the length of the corresponding side in EFGH.
Since EF = 1, then AB = 4 * 1 = 4
Answer: AB = 4
Angle A and angle E are corresponding angles, so they are congruent.
m<E = m<A = 30 deg
Answer: 30 deg
Answer:
Side AB= 4
Angle E= 30°
Step-by-step explanation:
6÷1.5=4
Scale factor is 4
1×4= 4
angle A = angle E

The two independent variables that would affect the number of days they took to hike the trail can be a) the speed of each person individually and b) the number of breaks each one takes.
What is an independent variable?It is a variable that stands alone and isn't changed by the other variables you are trying to measure.
Given that, Two friends hiked the Appalachian Trail from Georgia to Maine.
The two independent variables that would affect the number of days they took to hike the trail can be their respective speeds that will affect the numbers of days taken, and number of breaks they took, it can be amount of energy they are giving, or the number of days can be affected by any climate change also.
Hence, the two independent variables that would affect the number of days they took to hike the trail can be a) the speed of each person individually and b) the number of breaks each one takes.
