Find x when y=3 in the literal equation 3x+6y=24

Answers

Answer 1
Answer: when you plug in 3 in for y the equation is 3x + 6(3) = 24

3x + 18 = 24

subtract 18 from both sides

3x = 6

Isolate the x by dividing both side by 3

x = 2
Answer 2
Answer: 6x3=18
24-18= 6
so 3x=6 therefore x=2

What is 6 times 2/3 (two thirds)?

Answers

4. 6 times 2 is 12 and 12 divided by 3 is 4

Final answer:

The answer to the mathematical problem 6 times 2/3 is 4. This is solved by turning the whole number 6 into a fraction (6/1), multiplying the numerators together (6 times 2 equals 12), multiplying the denominators together (1 times 3 equals 3), and putting the new numerator over the new denominator (12/3), which simplifies to 4.

Explanation:

The question is asking you to multiply 6 by 2/3. Let's follow the steps to solve this multiplication problem.

  1. Turn the whole number, in this case 6, into a fraction by putting it over 1. This gives you 6/1.
  2. Multiply the top numbers (the numerators) together to get the new numerator. 6 * 2 = 12.
  3. Multiply the bottom numbers (the denominators) together to get the new denominator. 1 * 3 = 3.
  4. Put the new numerator over the new denominator to get your answer. 12/3 = 4.

So, 6 times 2/3 equals 4.

Answer: (B)35

Step-by-step explanation: the ratio of the lengths of the first rectangle compared to the length of the second is 30:25, or 6:5. Do the same for the width. the first rectangle has a width of 42. divide it by 6, (according to the ratio) which is 7. then multiply it by 5 (also according to the ratio) and you get 35.

Find the nth term of this sequence -4,-3,-2,-1,0

Answers

In order to find the nth term in a linear sequence, you simply find the difference between any two consecutive numbers, then subtract that number from the first sequence. 

-4 - -3 = -1
-4 - -1 = -3

The nth term is -n - 3

Monica’s school band held a car wash to raise money for a trip to a parade in New York City. After washing 125 cars, they made $775 from a combination of $5.00 quick washes and $8.00 premium washes.Let x represent the number of quick washes and let y represent the number of premium washes. Which system of linear equations represents the situation?
5x + 8y = 775 and x + y =125
5x – 8y = 125 and x + y = 775
5x + 8y = 775 and x – y = 125
5x – 8y = 125 and x – y = 775

Answers

Let x represent the number of quick washes and let y represent the number of premium washes.

1. One quick wash costs $5, then x quick washes cost $5x.

One premium wash cost $8, then y premium washes cost $8y.

They made $775 from a combination of quick and premium washes, then in total they made $(5x+8y) that is $775. The first equation is

5x+8y=775.

2. They had washed 125 cars, x cars by quick wash and y cars by premium wash, that is x+y in total. Then tha second equation is

x+y=125.

Only option A represents the situation.
Given:
quick washes = x ; $5
premium washes = y ; $8

x + y = 125
5x + 8y = 775

Correct answer is the 1st option.

x = 125 - y
5(125 - y) + 8y = 775
625 - 5y + 8y = 775
3y = 775 - 625
3y = 150
y = 150/3
y = 50 number of premium washes

x = 125 - 50
x = 75 number of quick washes
