Answer:

you have #5 correct and that is how I would do it.

you could also figure out the number of flowers and put 6 in each vase.

7x12= 84

84/6= 14.

I still think your way is best.

So...the way you did it you probably flipped the fraction and multiplied by the reciprocal.

You COULD have done it in the complete opposite way... instead of turning 1/2 into 2/1...do 1/7 instead of 7/1. This would get you to 1/14 and if you flip that, you get 14/1.

I will place 0 on the right side.

2x^2+3x+4 = 0

2 times 4 = 8.

What two numbers yield a product of 8 but when added produce a sum of 3, the middle term's coefficient?

There is no such number.

So, gotta use the quadratic formula.

I will set it up and let you do the math.

See attachment for the set up.

Solve the following: a) -5/4 [8/7+16/5]

Otrada [13]

Answer:

-38/7

Step-by-step explanation:

We are given $-\frac{5}{4}(\frac{8}{7}+\frac{16}{5})\\$ . First find the sum of the fractions in the parentheses. The greatest common multiple is 35 so we have $\frac{8}{7}+\frac{16}{5}=\frac{40}{35}+\frac{112}{35}$ .

The sum of $\frac{40}{35}+\frac{112}{35}$ is $\frac{152}{35}$ .

Now we multiply it by $-\frac{5}{4}$ so we have

$\\-\frac{5}{4} \cdot \frac{112}{35}\\=-\frac{1}{7}\cdot \frac{38}{1}\\=\boxed{-\frac{38}{7}}\\$

I need help please i

balandron [24]

Answer:

2 7/24

Step-by-step explanation:

First we have to add the gallons of two cow of each owner:

Hank's cows: 4 3/4 + 4 1/8

Add the whole numbers:

4 + 4 = 8

Now for 3/4 and 1/8

Find common

6/8 + 1/8

= 7/8

Put together :

8 7/8

Debra's cows: 5 1/2 + 5 2/3

Add the whole number

5 + 5 = 10

Now for 1/2 and 2/3

3/6 + 4/6

1 1/6

10 + 1 1/6

= 11 1/6

Since now we know that:

Hank - 8 7/8

Debra - 11 1/6

we can solve the question:

How many more gallons of milk did Debra's two cows produce on that compared to Hank's two cows?

Solution:

11 1/6 - 8 7/8

Subtract whole number

11 - 8 = 3

Now for 1/6 and 7/8

4/24 - 21/24

4-21/24

-17/24

2 7/24

Rao Construction recently reported $20.50 million of sales, $12.60 million of operating costs other than depreciation, and $3.00

NemiM [27]

Answer:

The correct option is e) $4.90

Step-by-step explanation:

Consider the provided information.

It is given that the Sales is $20.50 million

Operating costs excluding depreciation $12.60 million

Depreciation $3.00 million

Operating income (EBIT) = Net Earnings - Operating costs - Depreciation

Operating income (EBIT) = $20.50 - $12.60- $3.00

Operating income (EBIT) = $ 4.90

Hence, the correct option is e) $4.90

3 * 150 / 12

the second, you add the number of beads, so 20 beads, and put them into a fraction with how many beads the red and green are, so 8+6= 14
