Answer:
here a1=-14
d=a2-a1
d=-25-(-14)
d=-25+14
d=-11
as
an=a1+(n-1)d
a60=-14+(60-1)(-11)
a60=-14-59(11)
a60=-14-649
a60=-663
Step-by-step explanation:
Answer:
A. 5400-8x
B. $600
Step-by-step explanation:
5400-8x=600
8x=5400-600
x=4800/8=600
2 x - 5 y = 18 / * 4
3 x + 4 y = 4 / * 5 ( we will use the addition method )
--------------------------
8 x - 20 y = 72
+
15 x + 20 y = 20
-----------------------
23 x = 92
x = 92 : 23
x = 4
8 - 5 y = 18
- 5 y = 18 - 8
- 5 y = 10
y = 10 : ( - 5 )
y = - 2
Answer:
( x, y ) = ( 4, - 2 )
24 is the answer to your question
