Answer:
Step-by-step explanation:
a(20ft)
b(46ft)
c(72.6mm)
Y = 2x/x-7
x = 2y/y-7
xy - 7x = 2y
-7x = 2y - xy
-7x = y(2-x)
y = -7x / 2-x
y = 7x / x-2
f-¹(x) = 7x / x-2
There are 2001 items in that set.
So n(A) = 2001
We can individually count them all out, which is very slow and tedious, or we can use the formula
n-m+1
where,
m = starting value
n = ending value
In this case,
m = 0
n = 2000
So,
n-m+1 = 2000-0+1 = 2001
This formula only works if we increase the number by 1 each time (eg: 6, 7, 8, etc)
Answer:
y=9
Step-by-step explanation:
First we need to solve al addition and subtraction by performing the inverse operation. In this case, we need to add to reverse the subtraction
y/3 -4= -1
y/3= 3
Now we solve all multiplication and division again using the inverse operation, which in this case is multiplication, because the variable is being divided.
y/3=3
y=9
Thus we get that the value for y is 9.
Hope this helped!
Btw you're very pretty! <3
