Given :
Two equations :
-8x + 3y = -17 ....1)
3x - y = 7 ....2)
To Find :
The solution of the system.
Solution :
Multiplying equation 2) by 3 and adding with equation 1), we get :
(-8x + 3y) + 3(3x - y) = -17 + 21
x = 4
Putting above value of x equation 2) we get :
12 - y = 7
y = 5
Therefore, solution of system is ( 4,5 ).
Answer:
82
Step-by-step explanation:
You are looking for the hypotenuse.
c = ?
a = 80
b = 18
c^2 = a^2 + b^2
c^2 = 18^2 + 80^2
c^2 = 324 + 6400
c^2 = 6724
sqrt(c^2) = sqrt(6724)
c = 82 inches
Answer:
this should be the answer

Answer:
$4.00
Step-by-step explanation:
75% of 4
75% × 4 =
75/100 × 4 =
(75 ÷ 100) × 4 =
75 × 4 ÷ 100 =
300 ÷ 100 =
= 3
Hope this helps.
Answer:
It would be 55,200
Step-by-step explanation:
If she assumes her raise goes up by 5 % each year, her raise i n. 4 years will be 20%. So, 46,000x0.2= 9200. 9200+ 46,000 = 55,200.
