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:
18x + 20 + x = 10x -3
Combine like terms
19x + 20 = 10x -3
Subtract 20 to both sides because whatever you do on one side you have to do it on the other side:
19x = 10x -23
Subtract 10x
9x = -23
Divide 9 to isolate x:
x = -23/9
Simplify to get a mixed number:
x = -2 5/9
I would say kilograms, becauee kilograms would be the best metric unit for the mass of a television.
$750 / $30 = 25 maths teaching kids
$350 / $25 = 14 maths starter kits
if you wanted to see if it was right, you would just do 14*25 and you would get $350
hope I helped!!
