A+a+3=a+13
2a+3=a+13
From here you want the variables on the same side, so you would subtract the a from a+13 and move it to 2a+3
2a+3=a+13
-a -a
a+3=13
Now you want the numbers on the same side
a+3=13
-3 -3
a=10
Answer:
.0065
Step-by-step explanation:
You move the decimal backwards 3 times
The unknown vertex is on the perpendicular bisector of the opposite side. So the x coordinate is the same as that of the midpoint, x=(18+52)/2=35.
Answer:
90
Step-by-step explanation:
add them, then divide the answer by 5, because there are 5 numbers
in the f(t) = 15000(1.08)ᵗ, which is a form of a compounded interest formula, t = years, so
f(t) = 15000(1.08)¹⁰ , is the value of it when t = 10, after 10 years.
