Answer:
Three times the difference of two times a number and five is equal to 24, what is x?
Step-by-step explanation:
To write any equation in word problems, it is important to identify all your parenthesis operations by their technical names. Subtraction is a difference. So since we are multiplying it by 3, it becomes three times a difference.
Hello there, and welcome to Brainly!
In the following question, you are solving for the variable, x. Note the equal sign, what you do to one side of the equation, you do to the other.
Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction

First, add 2 to both sides of the equation:
10x - 2 (+2) = 38 (+2)
10x = 38 + 2
10x = 40
Next, divide 10 from both sides of the equation:
(10x)/10 = (40)/10
x = 40/10
x = 4
x = 4 is your answer.

2.5x1.30=3.25
4x4.50=18
2x3.75=7.5
3.25+18+7.5=$28.75 total price
2.5+4+2=8.5lb. total weight
28.75/8.5= 3.38 dollars per pound.
Answer:
The mean amount of time it takes people in her town to travel to work and towns= (t₁+t₂)/2
Step-by-step explanation:
Total population is 150000
Adult population is 90,000
The population for the old and kids will be 15000-90000=60000
Assume distance to town is D
Assume the speed taken by adults to travel to town is S₁ and that of the remaining group is S₂, then the time taken for travel will be;
Adults=D/S₁=t₁
Others =D/S₂=t₂
The mean amount of time it takes people in her town to travel to work and towns= (t₁+t₂)/2
Know the values for D, S₁ and S₂ to get the average time.
