Answers

Answer 1
Answer: The answer is $103.

To determine  how much Eileen will spend on gasoline, first we need to calculate how many gallons she needs.
If she drives 850 miles and her car gets 23 miles per gallon, we can use the proportion:
850 miles : x gallons = 23 miles : 1 gallon
Crossing the products:
x = 850 miles × 1 gallon ÷ 23 miles
x = 36.96 gallons

Thus, Eileen needs 36.96 gallons of gas. If the cost per gallon of gas is$2.79, using the proportion:
36.96 gallons : x = 1 gallon : $2.79
x = 36.96 gallons × $2.79 ÷ 1 gallon
x = $103.12 
x ≈ $103

Debate this math question 3-3x6+2

Answers

For this question BODMAS should be used
BODMAS = Bracket Of Division Multiplication Addition Subtraction

SO, in 3-3x6+2. multiplication should be done first
= 3-18+2           Next addition should be done
= 3-16                And now subtraction
= -13

Answer =  -13
The answer for 3-3x6+2 is 17. For this you need to use PEMDAS (Please Excuse My Dear Aunt Sally) to solve the problem. First, M stands for multiplication so you do 3x6 which is 18. Then, A is addition so add 2 to 18 which is 20. Lastly, S stands for subtraction so you subtract 3 from 20 and you get your answer, 17.

One number is 16 more than a second number. The sum of the first number and twice the second number is 139. What is the answer ?

Answers

Answer first number  = 57  second number = 41
x= 16 + y
x + 2y = 139

16+ y + 2y =139
16 + 3y =139
16-16 +3y = 139-16
3y = 123
3/3y = 123/3
y= 41

x= 16+y
x = 16+41
x= 57
