Answer 2

Step-by-step explanation:

For no. 3

x - 3 = 3 - x

x + x = 3 + 3

2x = 6

x = 6 / 2

x = 3

For no. 4

3(x + 4) = 3x + 4

3x + 12 = 3x + 4

3x - 3x = 4 - 12

0 = - 8

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:

If 1 1/2 (3/ 2) sections are 3/4 mile long.

So, in one section = 3/4 ÷ ( 3/2)

= 3/4 x 2/3

= 2/3

Hence, In each section 2/3 miles is covered.

A salesman at T-Mobile earns $12 for each phone he sells as well as an hourly salary of $18. Write and solve an inequality to determine the number of phones he must sell to earn $1000 in a 45-hour week.

Answers

He needs to sell 33 , your welcome :)

Answer is 16
P= (1000-18 times 45) divided by 12
So 1000-810 = 190 divided by 12 equals 15.8
But you can’t sell 15.8 phones so he has to sell 16, I’m bot very good at fighting inequalities so the inequality that I wrote might not be right

A $400 suit is marked down to $260. Find the percent of markdown.
A.0.35%
B.35%
C.65%
D.154%

Answers

The answer is B. -$140

Answer:

35%

Step-by-step explanation:

i dont know which letter it is bc a and b are the same answer and technically they are both right.

We can automatically assume that the answer isn't c or d because the suit didn't get marked down more than halfway.

We can't figure which letter is the correct one tho because answers a and b are the same.

Maya has 120 caramel apples to sell. Each caramel apple is covered with one topping. 1/5 of the caramel apples are covered with peanuts. 1/3 are covered with chocolate chips. 3/10 are covered with coconut. The rest are covered with sprinkles. How many of the caramel apples are covered with sprinkles? *

Answers

Answer:

20 caramel apples

Step-by-step explanation:

First we should make all of these have a common denominator. We could make these be 1/5 = 6/30, 1/3 = 10/30, 3/10 = 9/30. Now we can add them all up. 6 + 10 + 9 = 25/30. Now, to figure out how many apples is 1/30. 120 divided by 30 = 4. Now we can do 4*25 because that's how many non-sprinkle apples there are. This is 100. 120 - 100 = 20. You could have also done 4*5 because there were 5/30 sprinkle apples, and gotten the same answer.

3. 26:45
4. 45:26

Answers

Answer:

1. 19:26

Step-by-step explanation:

To solve you will first need to subtract like so;

90 - 38 = 52

so there are 52 females the ratio of male to females would be 38:52 then you would have to reduce the ratio.

If you divide both sides by two you get 19:26

Hope this helps and have a great day!

the answer is 19:26
