Add each side of perimeter together
The answer is 1. I got this by dividing 118 by 9 and the 9 times 13 which equals 117. 117+1= 118
Answer:
x=3
Step-by-step explanation:
Because it is equilateral, all the sides are equal. so you can make your equation
3(2x-3)=21
Distribute the 3 throughout, giving you 6x-3=21
Subtract the 3 from both sides, and you are left with 6x=18
Divide 18 by 6 and you get 3.
Answer:
-2.5
Step-by-step explanation:
Slope (m) =
ΔY
ΔX
=
-5
2
= -2.5
θ =
arctan( ΔY ) + 360°
ΔX
= 291.80140948635°
ΔX = 7 – 5 = 2
ΔY = -2 – 3 = -5
Distance (d) = √ΔX2 + ΔY2 = √29 = 5.3851648071345
Equation of the line:
y = -2.5x + 15.5
or
y =
- 5 x
2
+ 31
2
When x=0, y = 15.5
When y=0, x = 6.2
Answer:
NATHAN RODE 2 MILES
Step-by-step explanation:
Let N = Nathan's number of miles
Let M = 5N - 4 (Miguel rode his bicycle 4 miles less than 5 times the number of miles Nathan rode.
M = 6 (Miguel rode his bicycle 6 miles.)
6 = 5N - 4 (Substitute 6 for M in the equation above(M = 5N - 4).
6 + 4 = 5N - 4 + 4 (Add 4 to both sides of equation.)
10 = 5N
10/5 = 5N/5 (Divide both sides by 5 to isolate the variable N.)
2 = N
ANSWER: NATHAN RODE 2 MILES
CHECKING:
DOES MIGUEL'S 6 MILES EQUAL 5N - 4?
5N - 4 = (5)(2) - 4 = 10 - 4 = 6 MILES .
YES IT DOES.
