Simplify −3√27−2√2−3√45−√18 Work Needed

Answers

Answer 1

Answer:

Step-by-step explanation:

27 = 3 * 3 * 3

-3√27 = -3*3√3 = -9√3

Index of the radical is 2. So, after prime factoring, for each two of same number, pull one outside.

-3√45= -3√3*3*5 = -3*3√5 = -9√5

-√18 = -√2*3*3 = -3√2

-3√27 - 2√2 - 3√45 - √18 = -9√3 - 2√2 -9√5 -3√2

Now combine like terms

         = -9√3 - 9√5 -2√2 - 3√2

        = -9√3 - 9√5 - 5√2

Answer 2

Answer:

-9√3 - 5√2 - 9√5

Step-by-step explanation:

-3√27 = -3√9x3 = -3x3√3 = -9√3

2√2 = 2√2

3√45 = 3√9x5 = 3x3√5 = 9√5

√18 = √9x2 = 3√2

-9√3 - 2√2 - 9√5 - 3√2 = -9√3 - 5√2 - 9√5

Write a unit rate for the situation.
$12.50 for 5 ounces

Also if you can, with your answer can you tell me how to find unit rate?

Answers

Answer:

$2.50 for 1 ounce

Step-by-step explanation:

I hope this helps

Answer:

The correct answer is $2.50.

Step-by-step explanation:

The unit rate is what we use to determine the price of a single unit, when something is sold in a group, as in this case 5 ounces.

We have been told that $ 12.50 is the price for 5 ounces, but what we want to know is how much 1 ounce costs.

To determine this, what we must do is divide the total price by the quantity of ounces, in order to determine the unit price:

12.50 / 5 = 2.50

In this way we can verify that the unit price of 5 ounces

Answers

Answer:

y=

[tex] \frac{2}{15} [/tex]

x+10

Step-by-step explanation:

we know the y-intercept : (0,10)

picking another point on the line, (2,25)

finding slope is

[tex] \frac{y2 - y1}{ x2 - x1} [/tex]

so inserting that together is:

[tex] \frac{2 - 0}{25 - 10} [/tex]

that equals to,

[tex] \frac{2}{15} [/tex]

and since we already have the y-intercept you take the 10 to replace the b in the equation y=x+b

meaning x = slope and b = y-intercept

equation all together

y =

[tex] \frac{2}{15} [/tex]

x + 10

1675/3890 you are dividing 1675 by 3890 so it equals 0.43059...=0.4 simplified to the first decimal

If you want to divide it in long division then the answer would be, 0.430591

but if you want to simplify the fraction the answer would be

[tex] \frac{335}{778} [/tex]

or if u want it in percent form it would be, 43.059126%

and in decimal form it would be, 0.430591.

Answers

Answer:

C

Step-by-step explanation:

If we know that x is greater than or equal to 4, then we should substitute 4 in place of x in each possible solution.

A 4 + 3 ≥ 1   True, it's greater, but it can't be equal to.

B 3(4) ≥ 1     It's greater once again, can't be equal to.

C 4 - 3 ≥ 1     If x can also be greater than 4, then it works both ways. Equal and greater than.

Number 8 is A. 4, when a letter/variable is right beside number you multiply it. So since n=4, the equation should be 7 x 4 + 14= 42...also keep in mind the answer has to be less than 56

So A.4
