4x + 23x - 54x + 7
What is the answer?

Answers

Answer 1

Answer:

−27+7

Step-by-step explanation: First add 23x + 4x=27x

                                             Then subtract 54x gives you -27x

                                               You can't add a regular number with x's so your                                final answer is -27x+7

Answer 2

Answer:

−27x+7

The answer is 14 because -2 x -7 = 14. If you didn’t already know a sum is the value given when two or more numbers are multiplied together and the reason -2 and -7 multiply to get 14 is because the negatives cancel each other out to create a positive.
it’s just -9 since 2 + 7 is 9, but they’re opposite signs so it’ll be (-2) + (-7) = -9. The signs don’t change since both numbers are negative

After sales tax, A $96 watch costs $101.28. what is the sales tax percentage?

Answers

Answer:

i think it's 5.5 percent

Answer: The answer is 5.5% sales tax percentage

Step-by-step explanation:

First, subtract the total amount by the original amount

$101.28-$96= 5.28

Next, you would divide 5.28 by 96

5.28/96 = 0.055

The final part in which to get the answer is to multiply 0.055 with 100%

0.05·100= 5.5%

The X is equal to 1.75

Step-by-step explanation:

Answer: x=1.75

Step-by-step explanation:

rearrange the term: 3.5 (2.25 + x) = 14

the new term: 3.5 (x + 2.25) = 14

Combine multiplied terms into a single fraction, then distribute.  

x = 1.75

The gasoline consumption of a bus is 30l/100km and of a car is 9l/100km. To go on a 250 km trip, 30 people can either go by car with 5 people in each car or take one bus for all 30 people. Which method of transportation uses less gasoline, and how much less?

Answers

Answer:

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Case 1: Bus

Consumption/ 100Km= 301

and, for 250 Km= 301 /100 x 250

                          = 751

Case 2: Car

Total = 80 people

Total cars= 30/5 = 6

Consumption/ 100Km= 91

and, for 250 Km= 91 /100 x 250

                          = 22.51

Consumption by 6 cars = 6 x 22.51 = 1351

Difference between Gasoline Consumption = 1351-751 = 601

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ - 3.5 = - 4.6x - 5.1

Now,

Solve the expression as;

The expression is,

⇒ - 3.5 = - 4.6x - 5.1

Solve for x as;

⇒ - 3.5 + 5.1 = - 4.6x

⇒ 1.6 = - 4.6x

⇒ -4.6x = 1.6

⇒ x = 1.6 / - 4.6

⇒ x = - 16/46

⇒ x = - 8/23

Thus, The solution of the expression will be;

⇒ x = - 8/23
