Answer:
1/5 is left.
Step-by-step explanation:
Portion remaining after the bar was eaten by his brother = 1 - 1/5 = 4/5.
Portion remaining after John ate 3/4 of this = 4/5 - 3/4* 4/5 = 4/5 - 3/5
= 1/5.
Answer
Step-by-step explanation:
Both 1 and 2 equel up to 90 degrees
so to find x for 1 and 2 you would simplify the equations
90 = 6x - 3
and
90= 3x - 6
simplify them and you wil get the answers you want
another way to do it is combining the two and solve.
90 = 9x - 9
Just simplify :)
Answer: 4
Step-by-step explanation:
Set them equal to each other since they're both equal to y
3x-5=.5x +5
add 5 to both sides
3x=.5x+10
subtract .5x from both sides
2.5x=10
divide both sides by 2.5
x= 4

Answer:
-2018
Step-by-step explanation:
The n-th term is ...
an = a1 +d(n -1)
So, the given terms are ...
-53 = a1 +12d
-128 = a1 +37d
Subtracting the first from the second gives ...
(a1 +37d) -(a1 +12d) = (-128) -(-53)
25d = -75
d = -3
The 668th term will be ...
a668 = a1 +d(668 -1) = a1 +667d = (a1 +37d) +630d
a668 = -128 +630(-3) = -128 -1890 . . . . substitute for a38
a668 = -2018
