Answer:
(-6+y)-3y=28
-2y-6=28
-2y=34
y=-17
Then,
x=-6-17
x=-23
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
because 2/4 can be reduced to 1/2
To find the percent decrease from Saturday to Tuesday, you will find the difference between the number of customers on those days and divided by the total number of customers on Saturday.
By dividing this you will get a decimal, which then can be converted to a percent.
80-17= 63
63/80 = 0.7875
0.7875 = 78.75%
There was a 78.75% decrease from Saturday to Tuesday.
Answer:
8 years
Step-by-step explanation:
Compound interest formula

A(t) is the final amount 55000
A_0= 40000, r= 4% = 0.04, for quarterly n=4

divide both sides by 40000


Take ln on both sides

divide both sides by ln(1.01)

Divide both sides by 4
t=8.00108
So it takes 8 years
