Disclaimer: Exchange rates vary almost on a constant basis, so it is best to always have an up-to-date chart from an online source. For the purposes of this problem, we don't have to worry about the rates changing.
------------------
25 U.S Dollars = 20 Euros
25/20 U.S. Dollars = 20/20 Euros
1.25 U.S. Dollars = 1 Euro
<h3>The exchange rate is 1.25 U.S. Dollars per Euro</h3>
Saying "per Euro" is the same as saying "per 1 Euro". I divided both sides of the second equation by 20 so that I could turn the "20 Euros" into "1 Euro".
8 + 11 = 40
there is a pattern. 1+4=5, the answer from the previous equation 5+2+5=12, 12+3+6=21, 21+8+11=40.
8+11=40
Question is Incomplete; Complete question is given below.
Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options. Negative 80 x + 24.5 y minus 56 Negative 80 x + 28 y minus 56 80 x + 28 y + 56 4 (negative 20 x + 7 y minus 14) Negative 4 (negative 20 x + 7 y minus 14)
Answer:
Negative 80 x + 28 y minus 56
4 (negative 20 x + 7 y minus 14)
Step-by-step explanation:
Given:

We need to find the equivalent expression for given expression.
Solution:

First we will apply distributive property for given expression.

So we get;

Hence first expression equivalent to given expression is
.
Now again evaluating the expression we get;
We will take 4 as common factor from the expression we get;

Hence second expression equivalent to given expression is
.
This expression has three terms: the variables x, y, and z. We say that the first term is x, that the second term is y, and so on. This expression also has three terms: the number 7, the function f(x), and the variable a.
