Answer:
Step-by-step explanation:
a(1) = -7 (given)
a(2) = a(1) + 4 = -7 + 4 = -3
a(3) = a(2) + 4 = -3 + 4 = 1
a(4) = a(3) + 4 = 1 + 4 = 5
and so on.
Answer:
17/20
Step-by-step explanation:
85% can easily be written as 85/100 and this is true, but we have to simplify to the simplest form.
An easy way to simplify is to divide the numerator and denominator by the GCF (Greatest Common Factor)
The GCF of 85 and 100 is 5.
85 ÷ 5 = 17
100 ÷ 5 = 20
We can no longer simplify 17/20 because 17 is prime so your final answer is 17/20!

Answer:
In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Step-by-step explanation:
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations, and other aspects of logical syntax. Many authors distinguish an expression from a formula, the former denoting a mathematical object, and the latter denoting a statement about mathematical objects.
You just add them together. First, you give them all the same denominator. So 2 3/4 goes to 2 6/8 and 1 1/2 goes to 1 4/8. 1 4/8 + 2 6/8 + 7/8 = 3 17/8. 3 17/8 simplified = 5 1/8. So 5 1/8 inches
