Answer:
-2 = n
Step-by-step explanation:
-3 + 4n = 4n + 3 + 3n
-3 + 4n = 7n + 3 [Combine like-terms]
-7n -7n
________________
-3 - 3n = 3
+3 +3
________________
-3n = 6
n = -2

Answer:
0.26
Step-by-step explanation:
I am pretty sure the equation for this is 9x12+108 inches then divide 28.08 by 108 and you should get 0.26.
Answer:
-5
Step-by-step explanation:
Given the two box plots showing the number of seconds the students completes the 50-meter-dash race before and after the program, we are to determine the difference between the median value of seconds before and after the program.
Median in a box plot is represented by the vertical line that divides the rectangular box in a box plot.
Thus, the median before the program = 15 seconds
The Median after the program = 10 seconds
The median change = 10 - 15 = -5 seconds.
This means, after the program, most of the students now finish the 50-meter-dash faster, about 5 seconds less the former seconds used before the program.
Answer:
x = 2, y = 6
Step-by-step explanation:
Δ WXY is equilateral ( 3 congruent angles ), then the sides are equal
WY = WX , that is
y - 1 = 5 ( add 1 to both sides )
y = 6
Δ WYZ is isosceles ( 2 congruent base angles ) then the legs are congruent
YZ = WY , that is
x + 3 = 5 ( subtract 3 from both sides )
x = 2
These are really easy and it’s worth the points
