3y+2/4=7 I don't understand this at all

Answers

Answer 1

Answer: Don't let the fraction confuse you.

3y + 2/4 = 7

You could multiply each side by 4 to get rid of the fraction:

12y + 2 = 28

Subtract 2 from each side:

12y = 26

Divide each side by 12 :

y = 26/12 or 13/6 or 2 and 1/6

Answer 2

Answer: Actually u want to find the value of 'y' step1:rearranging 3y=7-2/4 step2:take LCM and subract 3y=26/4 step3:simplify 3y=13/2 y=13/6

Given f(x)=x^2+3 and g(x)=x+5/x. Find (g o f)(4)

Answers

To find g(f(4)), work from the inside out.

f(4) is 4^2+3, or 16+3, or 19. Now, we must find g(19).

This is 19+5/19. This is already a mixed number, though if you want an improper fraction solution, we have:

361/19+5/19

Which simplifies to:

366/19

Therefore, 366/19 is the answer.

What are the steps to solving the inequality 3b + 8 ≥ 14

Answers

Answer:

The solution of the given inequality $3b+8\geq 14$ is: $[2, \infty)$

Step-by-step explanation:

Given the inequality equation: $3b+8\geq 14$

Subtraction property of equality states that you subtract the same number to both sides of an equation.

Subtract 8 to both sides of an equation.

$3b+8-8\geq 14-8$

Simplify:

$3b\geq 6$

Division property of equality states that you divide the same number to both sides of an equation.

Divide both sides by 3 we get;

$(3b)/(3) \geq (6)/(3)$

Simplify:

$b\geq 2$

therefore, the solution of the given inequality is: $b\geq 2$ or $[2, \infty)$

3b+8≥14
Subtract 8 from both sides
3b≥14-8
3b≥6
Divide both sides by 3
b≥6/3
b≥2

Ariel deposited $100 into a bank account. Each friday she will withdraw 10% of the money in the account to spend. Ariel thinks her account will be empty after 10 withdrawls. Do you agree explain.

Answers

Answer: Yes, I agree. $10 will be withdrawn every Friday, resulting in the $100 she deposited being completely gone after 10 withdrawals.

Step-by-step explanation: You will want to find the amount of money being taken from the $100 withdrawal first. Turn the percent into a decimal, which should result to 0.10. Take this decimal and multiply it with 100 to get the amount of money being taken out of the account each week, which should be $10. I would go about answering this by multiplying the $10 by the amount of 10 withdrawals. This would result in 100. This answers the question because we are trying to see if 10 withdrawals will completely deplete the $100 in the account.

One container holds 1 1/7 quarts of water and second container holds 5 3/4 quarts of water how many more harts of water does the second container hold then the first

Answers

Answer:

129/28 (4.6 approx.)

Step-by-step explanation:

The first hols 1 1/7 quarts, it is: 1 + 1/7

Using 7 as common denominator and summing:

1 + 1/7 = 7/7 + 1/7 = 8/7

The second holds 5 3/4 which is: 5 + 3/4. Using 4 as common denominator:

5 + 3/4 = 20/4 + 3/4 = 23/4

Now we need to know how much greater is 23/4 than 8/7. For comparing them we need to set them to a common denominator. The easiest way is use a number that is multiple of both, 4 and 7, lets us 28. We need to multiply the numerators by the number that, multiplied by denominators gives us 28. For the first is 4, and for the second 7.

8/7 = (8*4)/7*4=32/28

23/4= (23*7)/4*7 = 161/28

Now, we only have to subtract:

23/4 - 8/7 = 161/28 - 32/28 = 129/28

So, the second container has 129/28 more quarts of water (approx. 4.60) than the first.

1/3 :4= x/6
