Consecutive odd integers are separated by 2. The 3 consecutive odd integers are

n + 2

(n + 2) + 2 = n + 4

Given:

n + (n + 2) + (n + 4) = 51

3n + 6 = 51

n = (51 - 6)/3 = 15

n + 2 = 15 + 2 = 17

n + 4 = 15 + 4 = 19

so your final numbers are 15, 17, and 19

When factoring x2 – 3xy + 2y2 by grouping the first step can be:

blagie [28]

Answer:

x^2 – 3xy + 2y^2

Step-by-step explanation:

Factor the following:

x^2 - 3 x y + 2 y^2

Hint: | Factor the quadratic x^2 - 3 x y + 2 y^2.

The factors of 2 that sum to -3 are -1 and -2. So, x^2 - 3 x y + 2 y^2 = (x - 1 y) (x - 2 y):

Answer: (x - y) (x - 2 y)

A group of friends were working on a student film. They spent all their budget on props and costumes. They spent $693 on props,

sergeinik [125]

Answer:

The total budget is $1260

Step-by-step explanation:

Given

$Props = \$693$

$Costumes = 45\%$

Required

Determine the total budget

Since all budgets was spent on Props and Costumes only.

We have that.

$\%Props + \%Costumes = 100\%$

$\%Props + 45\%= 100\%$

$\%Props= 100\% -45\%$

$\%Props= 55\%$

In other words, 55% was spent on Props

Let the total budget be x, we have:

$55\% * x = \$693$

Make x the subject

$x = \$693/55\%$

$x = \$1260$

Hence, the total budget is $1260

A pharmacist has 80 milileters of a 25 percent saline solution. Which expression can be used to find the percentage of the conce

Thepotemich [5.8K]

Answer:

Step-by-step explanation:

Final concentration % = [grams of salt / mililiters of solution] * 100

grams of salt = grams of salt from solution 1 + grams of salt from solution 2

grams of salt from solution 1 = mililiters * %/100 = 80 mililiters * 0.25 g/mililiters = 20 g

grams of salt from solution 2 = mililiters *%/100 = x*0.10 g/mililiters = 0.1x

mililiters of final solution = mililiters from solution 1 + mililiters from solution 2

mililiters of final solution = 80 mililiters + x mililiters

=> Final concentration, % = [0,10x + 20 g] / [x + 80 mililiters] * 100
