NEED HELP WITH THIS MATH QUSTION

Answer:

20,9

Step-by-step explanation:

this is how I did=x=1st, y=2nd; x=4y-16 and x+y=29; thus 4y-16+y=29; 5y-16=29; 5y=45; y=45/5=9, once you know y=9, put in equation, 4y-16=×, (4*9)-16=x, 36-16=x, 20=x

The system of equations are x + y = 29 and y = 4x - 16

The two numbers are 9 and 20 respectively

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first number be x

Let the second number be y

Now , the equation will be

One number is 16 less than 4 times the second number

So , y = 4x - 16   be equation (1)

And , Sum of the numbers is 29

So , x + y = 29   be equation (2)

And , y = 29 - x  be equation (3)

Substituting the value of y from equation (3) in equation (1) , we get

29 - x = 4x - 16   be equation (4)

On simplifying the equation , we get

Adding x on both sides of the equation , we get

5x - 16 = 29

Adding 16 on both sides of the equation , we get

5x = 45

Divide by 5 on both sides of the equation , we get

x = 9

Substituting the value of x in equation (2) , we get

y = 20

Therefore , the two numbers are 9 and 20

Hence , the equations are solved

Hi there!

How are you?

Answer:

[tex]\boxed{y = - x - 7}[/tex]

Step-by-step explanation:

⇒ First add 3x to both sides.

[tex]-3x - 3y + 3x = 21 + 3x[/tex]

[tex]-3y = 3x + 21[/tex]

⇒ Second divide both sides by -3.

[tex]\frac{-3y}{-3} = \frac{3x + 21}{-3}[/tex]

[tex]y = - x - 7[/tex]

Step-by-step explanation:

Answer:

Olivia is 24 years old

step by step

because Olivia is 20 years old and Mike is 4 years older than her so Olivia is 24 years old

Answer: Olivia is 8 years old.

Step-by-step explanation:

"O" stands for Olivia

O+4 = M

O + O+4 = 20

2O +4=20

2O=16

2O/2 = 16/2

O = 8

Mike is 4 years older, so Mike is 12 years old

12+8 = 20

Answer:

$104.70

Step-by-step explanation:

The equation would be set up like this: 80.45 + 20.50(3) - 37.25. You started off with $80.45 in your bank account and deposited, or added, $20.50 every day on Tuesday, Wednesday and Thursday. That would mean you added $20.50 three times. Adding $80.45 + $20.50 + $20.50 + $20.50, simplified to $80.45 + $20.50(3)  would get you $141.95 in total. Then, on Friday, you withdraw $37.25, getting the equation $141.95 - $37.25, leaving $104.70 for the weekend.

Answer:

$104.70.

Step-by-step explanation:

If you started with $80.45, and then deposited $20.50 3 times, one for Tuesday, Wednesday, and Thursday, that would get you up to $141.95. Then, if you withdrew $37.25 on Friday, that leaves you with $104.70 for the weekend.

Answer:

$46

Step-by-step explanation:

Let each pair of jeans cost $x.

Total sum of money= cost of 5 pairs of jeans +amount left

[tex]240 = 5x + 10[/tex]

-10 on both sides:

[tex]5x = 240 - 10[/tex]

Simplify:

[tex]5x = 230[/tex]

Divide by 5 on both sides:

[tex]x = \frac{230}{5} \\ x = 46[/tex]

Thus, each pair of jeans cost $46.

Answer:

$46

Step-by-step explanation:

240-10=230 divided by 5= 46

Answer:

Step-by-step explanation:

You basically just move three places forward from the last number which is 7.

Answer:

The other endpoint is (7, -5)

Step-by-step explanation:

We can use the formula for the midpoint to find the coordinates of the other endpoint of the segment BC:

xm = x1 + (x2 - x1)/2

ym = y1 + (y2 - y1)/2

For our case, replacing the given coordinates and solving for x2 and y2 (the coordinates of the other endpoint) we get:

For x2:

xm = x1 + (x2 - x1)/2

5 = 3 + (x2 - 3)/2

5 - 3 = (x2 - 3)/2

2 = (x2 - 3)/2

4 = x2 - 3

x2 = 4 + 3 = 7

For y2:

ym = y1 + (y2 - y1)/2

-2 = 1 + (y2 - 1)/2

-2 -1 = (y2 - 1)/2

-3 = (y2 - 1)/2

-6 = y2 - 1

y2 = -6 + 1 = -5

Therefore the other endpoint is (7, -5)

Answer:

1200 mcg

Step-by-step explanation:

Formula = mg multiply by 1000

1.2 mg × 1000

= 1200 mcg

How to Convert Milligrams to Micrograms

1 milligram (mg) is equal to 1000 micrograms (μg).

1 mg = 1000 μg

The mass m in micrograms (μg) is equal to the mass m in milligrams (mg) times 1000:

m(μg) = m(mg) × 1000

1.2 milligrams is equal to 1200 micrograms.

We have,

The prefix "milli-" in milligrams indicates a thousandth (1/1000), and the prefix "micro-" in micrograms indicates a millionth (1/1,000,000).

To convert from milligrams to micrograms, we need to multiply the value in milligrams by a conversion factor of 1000, as there are 1000 micrograms in 1 milligram.

In this case,

We have 1.2 milligrams (1.2 mg) that we want to convert to micrograms.

We can set up the conversion as follows:

1.2 mg x (1000 mcg/1 mg)

By multiplying 1.2 mg by the conversion factor (1000 mcg/1 mg), the milligram units cancel out, leaving us with the desired unit of micrograms. The calculation is:

1.2 mg x (1000 mcg/1 mg) = 1200 mcg

Therefore,

1.2 milligrams is equal to 1200 micrograms.

The conversion factor of 1000 was used because there are 1000 micrograms in 1 milligram.

Answer:

The fish is approximately 81.35 feet down

Step-by-step explanation:

Notice that the 200 ft chord at a 24 degrees angle of depression means that you are dealing with a right angle triangle, where the chord is the hypotenuse, and the fish's depths is the side opposite the 24 degree angle. So you can use the definition of the sine function in a right angle triangle:

[tex]sin(\theta)=\frac{opposite}{hypotenuse} \\sin(24^o)=\frac{x}{200} \\x = 200 \,*\,sin(24^o)\\x \approx 81.35\,\,ft[/tex]

Answer:

[tex]f(x)=\frac{3}{2}x+4[/tex]

Step-by-step explanation:

The Slope-Intercept Form equation is f(x)=mx+b

m= slope

b= y-intercept

you are already given the slope ([tex]\frac{3}{2}[/tex]), so you only have to find the y-intercept.

first, plug in the x of the point given (-6) into the equation

[tex]\frac{3}{2}[/tex](-6)=-9

then you find the difference of the answer and the y of the given point (-5)

-5-(-9)

-5+9=4

b=+4

==============================================

Explanation:

Let's add the lengths across the top

(2x+7)+(2x-1)

2x+7+2x-1

(2x+2x)+(7-1)

4x+6

The total horizontal length of the two rooms combined is 4x+6

Multiply this with the vertical length (x+3) getting

(4x+6)(x+3)

y(x+3) .... see note below

y*x + y*3

x(y) + 3(y)

x(4x+6) + 3(4x+6)

4x^2+6x + 12x + 18

4x^2+18x+18

which is the total area of both rooms combined

Note: I replaced (4x+6) with y in step 2 above. That helps with distribution though it's not mandatory. You could also use the FOIL rule or the box method as alternative options.

Another alternative option is to find the area of each individual room and then add up the two smaller areas to get the larger total area.

Answer:

r = 1

Step-by-step explanation:

Step 1: Write equation

-3r + 18 = 15r

Step 2: Solve for r

Step 3: Check

Plug in r to verify it's a solution.

-3(1) + 18 = 15(1)

-3 + 18 = 15

15 = 15

Step-by-step explanation:

- 3r - 15r = -18 .... Moved variables to one side and constants to the other

- 18r = - 18 ..... Simplified

r = 1 ..... Divided to isolate the r

Check:

Plug in 1 for r

-3(1) +18 = 15(1)

- 3+18 = 15

15 = 15 .... Therefore 1 is correct

Answer is 1
