A triangles measure = 180
45 + 35 + x = 180
80 + x = 180
x = 100
Hope this helps!
Answer:
Step-by-step explanation:
To find tax on something you multiply the base price by the tax percentage. So if something is 100 dollars and tax is 5 percent (or .05 in decimal form), you would add 5 dollars to the price. because 100*.05=5.
If we assume 6% as the tax then we multiply 22.50*.06 = 1.35, so you will add 1.35 to the price. That means the new price is 22.50 + 1.35 = 23.85.
It's just asking for what the tax is though so the answer is 1.35 at 6%. The question does say the tax is over 6% though, so that means the tax will only go up from there if the tax is over 6%
Answer:
x=20
Step-by-step explanation:
2x-25=15
2x=40
x=20
F(n) = 75*1/5n
This is because the base value would be 75 and it is divided by 5 each part of the sequence.
The summation of negative 5 n minus 1, from n equals 3 to 12 can be
expressed as
n = 3/12
substitute the value of n to the equatio
-5n – 1
-5( 3/12 ) -1
-9/4
