The best way to solve is by using elimination method.
20x = -58 - 2y
17x = -49 - 2y
Multiply second equation by -1
20x = -58 - 2y
-17x = 49 + 2y
Add equations.
3x = -9
Divide.
x = -3
Plug in -3 into one of the equations.
17(-3) = -49 - 2y
-51 = -49 - 2y
Add 49 to both sides.
-2 = -2y
Divide.
1 = y
So your solution is (-3, 1).

Answer:
10√3 feet
Step-by-step explanation:
In a 30-60-90 triangle;
-Long leg = long leg
-Short leg = 1/2 * long leg
-2nd longest leg = short leg * √3
-Long leg = 20
-Short leg = 1/2 * long leg = 10
-2nd longest leg = short leg * √3 = 10√3
Answer:
2
Step-by-step explanation:
Hey There!
When it ask for the scale factor its asking for what did you have to multiply the side length by of figure a to get the similar side length of figure b
for example in figure A the base length is 7
to get the the base length of figure B (14) they multiplied the base length of figure A by 2
7x2=14
therefore the scale factor is 2
Answer:
7.86 is the answer
Step-by-step explanation:
30% of 24.50 is 7.35.
