Answer:
1. 32,
2. 160,
3. 5,
4. 5, and
5. 15.
Step-by-step explanation:
<em>Algebraic expressions</em> include both <u>alphabet </u>and <u>number</u> so that the value of the <u>alphabet</u> is to be <em>determined</em>. Thus the steps taken by Tyler are correct if x = 22.
ii. Tyler made no mistake.
<em>Algebraic expressions</em> include both <u>alphabet</u> and <u>number</u> so that the <em>value</em> of the <u>alphabet</u> is to be determined. The <u>value</u> of the <u>alphabet</u> in the <em>expression</em> would be determined by applying <em>mathematical operations</em> appropriately.
To solve the <u>question</u> given to Tyler, we have:
= -5
<u>square</u> both <em>sides</em> of the equation to have;
(x + 3) = 
x + 3 = 25
collect <em>like terms</em> to get;
x = 25 - 3
= 22
x = 22
1. Thus the equation is true if x = 22.
2. <u>Tyler</u> did not make any <u>mistake</u> in solving for x.

#SPJ 1
Answer:
franchise fast-food restaurant located in the Northeast specializing in halfpound hamburgers, fish sandwiches, and chicken sandwiches. Soft drinks and French fries are
also available. The planning department of Bun-and-Run Inc. reports that the distribution of
daily sales for restaurants follows the normal distribution and that the population standard
deviation is $3,000. A sample of 40 showed the mean daily sales to be $20,000. Find the 95%
confidence interval for the population mean.
Answer : 1618
Step-by-step explanation: add 128 and 254 together and you get 382. subtract that from 2000.
Final answer : 1618
