if x:y = 2:5, find the value of (x + y) : (2x-3y)

Answers

Answer 1

Answer:

(x + y) : (2x-3y) = - 7/11

Step-by-step explanation:

The ratio is denoting:

x = 2

y = 5

Substitute your values into the equation's variables (x and y). Then solve.

(x + y) : (2x-3y)

(2 + 5 ) : [2(2) - 3(5) }

7 : [4-15]

7: -11

ratios can be turned into fractions.

7: -11 is the same thing as - 7/11

Activity 1: rewrite me!

1. write the equation 2x+3y=12into y=mx+b
Solution
2x+3y=12
2x + (____) + 3y = 12+(-2x)
(____)3y=(-2x+12)(____)

y= - ⅔x +4

Given:


Simplified as y= mx+ b

2.write the linear equation y= -2x -1 into Ax + By = C.

solution
y = -2x-1
y +(____) = - 2x + (___) - 1

2x + y = -1

Given:



Questions:
1. how did you write the linear equation y = mx + b to the form Ax + By = C?

2. how did you write Ax + By = C?

3. what mathematical concepts or principles did you apply to write each linear equation to standard form?
to y=mx+b form?

1) The equation 2y + 3x = 12 in the y = mx + b form is [tex]y = -\frac{2}{3} x + 4[/tex]

2) The linear equation y = -2x - 1 in the Ax + By = C form is 2x  +  y  =  -1

The point-slope form of the equation of a line is y = mx + b

where m represents the slope

b represents the y-intercept

The given equation is:

2x  +  3y  =  12    (Given)

Subtract 2x from both sides

2x  +  (-2x)  +  3y   =  12  +  (-2x)

3y   =  12 - 2x  (Equality property of addition)

3y   =  -2x  +  12 (Commutative property of addition)

Divide both sides by 3

[tex]\frac{3y}{3} = -\frac{2}{3} x + \frac{12}{3} \\\\y = -\frac{2}{3} x + 4[/tex](Equality property of division)

2) Write the linear y = -2x - 1 into Ax + By = C

y   =   -2x  -  1  (Given)

Add 2x to both sides

y  +  2x  =  -2x  + 2x - 1 (Equality property of addition)

y   +  2x   =  -1

2x   +   y   =   -1   (Commutative property of addition)

Your boss sends you to the hardware store to buy tie down rope. He tells you to buy the best deal. What is the savings per unit between the best deal and worst deal?

A) $50.00

B) $25.00

C) 5 cents

D) 14 cents

Answers

Answer:

D. 14 cents

Step-by-step explanation:

At 10 feet for $7, that is 70 cents for every foot

At 20 feet for $13, that is 65 cents for every foot

At 50 feet for $28, that is 56 cents for every foot

At 100 feet for $57.50, that is 58 cents (rounded) for every foot

The best deal is 50 feet at 56 cents

The worst deal is 10 feet at 70 cents

So we do 70 - 56 = 14

So the answer is the savings per unit between the best deal and worst deal is 14 cents

what is the average hourly pay of someone making $45,000per year. Assuming wage growth of 5% a year, how much would he make the second year

Answers

Answer:

When it’s time for annual performance reviews, if you plan on including pay raises, you need to know the simple math behind calculating pay increases correctly. Raises can be based on any number of things including a worker’s piers, standard industry rates, length of time on the job, the amount of work to do, and even whether or not the boss likes the employee or not. There are few, if any, laws that govern how and when increases are granted, so it’s up to you to determine what you’re willing to give.

Answer:

See below

Step-by-step explanation:

Assume the person works 40 hours a week and 52 weeks a year.

The hourly pay would be:

$45000 ÷ (40*52) = $45000 ÷ 2080 =$21.63

The yearly income the second year:

$45000 + 5% = $45000*1.05 = $47250

Answer:

X=12.75

Y=12

Step-by-step explanation:

4X+8°+31°=90°

4X=90-39/4°

X=12.75°

3Y+86=8Y+26

86-26=8Y-3Y

60=5Y

Y=60/5

Y=12

Answer:

x = 12.75

y = 12

Step-by-step explanation:

To solve for x, we can see that it makes up a right angle when placed next to the 31 degrees.

We also know that the corner should equal 90 degrees, so we can set this up:

4x+8+31=90

Group like terms:

4x=51

Divide:

x=12.75

To solve for y, we can see that two expressions equal the same length, so:

8y+26=3y+86

Group like terms:

5y=60

y=12

You can also plug in x and y in to see if they match up

4(12.75)+8+31=90

51+8+31=90

90=90

and

8(12)+26=3(12)+86

96+26=36+86

122=122
