NEED HELP ASAP!!!! PLEASE HELP!!!!

Answer:

Step-by-step explanation:

and I'll explain why so when when we're

looking into combining fractions

positive negative fractions the main

important thing we need to make sure we

have is like denominators

all right common dinar common

denominator the easiest the easiest way

to find a common denominator is to

multiply the denominators right that's

the easiest way to go ahead and find one

just multiply three times eight which is

24 that's gonna give you your comments

and on there does that make sense so

make sense multiply the denominator but

that's not always going to be the least

common denominator so an easy way to

always check to find the least common

denominator is choose the largest

denominator which would be 8 and then

kind of list out the multiples so is and

sitting determine it does 3 divide into

any of those multiples before we get to

24 so just 3 to buy an 8 no so 8 is not

the least common denominator then we go

to 16 just 3 divided into 16 No

24 yes it does so actually end up 3

times 8 is gonna equal 24 and it's okay

lays knowing if you always want to

multiply your denominators you can

always do that but that just because

you're multiplying you're not always

gonna get the least common denominator

and the problem with that is you're

gonna have to simplify your fraction a

little bit more at the end all right but

it is also a way to always get a common

denominator so my lcd is 24 and what I

like you guys to do is always like write

that down so you can always kind of

remember it and basically when we have

an LCD of 24 what we want to be able to

do is say alright what do I need to

multiply now both of my denominators by

to get to 24 well to get 3 forget about

the negative sign per second for do get

3 we need to multiply by 8 right but

there's a problem if you have a fraction

and you only multiply the denominator by

it you've now changed the fraction think

about 1/2 if you have 1/2 and you

multiply the denominator by 3 you now

have 1/6 right is 1/6 equal to 1/2

no so we need to multiply the numerator

and the denominator by 8 think about

again 1/2 times 3 over 3 equals 3 over 6

is 3 over 6 equivalent to 1/2 yes so

when you're multiplying your fraction we

want to make sure we

keep equivalent fractions for 3/8 we

need to multiply by five over five and

then when I multiply fractions I just

simply multiply across numerator times

numerator denominator times denominator

therefore I get negative 8 over 24 plus

I don't know 3 right thank you I don't

know I was like off in my own world I

guess there you go

sorry so therefore now I have negative 8

24 plus 9 over 24 and now when we need

to add combined fractions we need to

combine fractions as long as they have

common denominators we just add or

subtract our numerators so just think

about negative you owe eight dollars you

have nine dollars in your pocket

therefore you're gonna have one dollar

left right and you keep the denominator

the same question okay letting it

internalize

Answer:

The answer is -6x + 6

Step-by-step explanation:

For us to have an infinite number of solutions, then, what we have on the right hand side will be exactly what we have on the left hand side

Since we have -6x + 6 on the left hand side

To have infinite number of solutions, what we have on the right hand side will be the same

Thus, we have -6x + 6 on the second side

Answer:

The temperature was;

6 °C

Step-by-step explanation:

Here, we want to know the temperature at 5 pm

For the first 6 hours, we have an increase of 3/4 degree per hour

so the temperature increase in the first 6 hours will be;

6 * 3/4 = 4.5 degrees

Then we had an increase of 1 1/2 degrees per hour for 5 hours

The increase after these 5 hours will be;

3/2 * 5 = 15/2 = 7.5 degrees

Total increase is 7.5 + 4.5 = 11 degrees

We subtract the initial -5 from here

So the present temperature will be;

-5 degree + 11 degree = 6 degrees celsius

Answer: B

Step-by-step explanation:

Each month, the person seems to grow taller. So, there IS a positive association between height and age.

Answer: Length = 10cm

Width = 6cm

Step-by-step explanation:

First and foremost, we should note that

1 meter = 100 cm.

Therefore,

Length = 5m = 500 cm

Breadth = 3m = 300 cm.

Since Elena wants to make a scale drawing of 1 to 50, then

Length = 500 cm / 50 = 10 cm

Breadth = 300 cm / 50 = 6 cm.

Therefore, the length of the scale drawing will be 10 cm and the width of the scale drawing will be 6cm.

Answer:

2.666666666666666666666666 ( repeating decimal )

Step-by-step explanation:

It says a 45 foot slide casts a 30 foot shadow.

We notice that 30 is exactly 2 / 3 of 45.

A easier way to notice that is like 30 + (half of 30 which is 15)

so 30 + 15 is 45 which is exactly the height of the water slide.

The we take the 4 foot child. It is 4 foot.

Then we do 4 times 2 / 3 which we got earlier.

which will be 2.66666666666666666666666666666666666

repeating decimal don't know how to write it here

Answer:

x = 5.75ft/2.3ft

Step-by-Step:

34ft/13 [tex]\frac{3}{5}[/tex]   =  5.75ft/x

34x = 13 3/5 · 5.75

34x ÷ 34 = 78.2 ÷ 34

34ft/13 3/5ft = 5.75ft/2.3ft

Answer:

There are 15 Black tokens.

Step-by-step explanation:

If the ratio is 8:5 we divide 24 by 8 to get 3. We then do 5 x 3 for the black tokens and get 15.

The number of black tokens in the bag are 15.

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

In the bag, there are 24 green tokens in the bag.

And, The ratio of green tokens to black tokens is 8 to 5.

Now,

There are 24 green tokens in the bag.

And, The ratio of green tokens to black tokens is 8 to 5.

So, Number of green tokens = 8x

And,  Number of black tokens = 5x

Hence, We can formulate;

⇒ 8x = 24

⇒ x = 3

Thus, Number of black tokens = 5x

                                               = 5 × 3

                                               = 15

Therefore, The number of black tokens in the bag are 15.

Answer:

Use the two ordered pairs to find the slope, m.

Then substitute one set of ordered pairs and m into y = mx + b to solve for b

Step-by-step explanation:

If we are given two ordered pairs of a function and we need to write an equation that represents the linear function, first, what we need to do is to use the two ordered pair to find the slope, m, using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex].

After getting the slope (m), find the value of the y-intercept (b), by substituting the value of one of the ordered pairs and the slope value (m) into y = mx + b.

Once the value of m and b is known, plug in the value of m and b into y = mx + b to derive the equation of the linear function.

Use the 2 ordered pairs to find the slope, m .

Then substitute m and one set of ordered pairs into y = mx + b to solve for b.

If given the 2 ordered pairs for a function, the ordered pairs can be first used to find the slope of the function.

For example

(x₁, y₁)(x₂, y₂)

m = slope = y₂ - y₁ / x₂ - x₁

The slope(m) is then substituted in the slope intercept form equation.

y = mx + b

where

m = slope

b = y-intercept

And one set of the ordered pairs is also substituted in the equation to get the value of the y-intercept(b).

Answer: 58.5 mg

Step-by-step explanation:

Given: Recommended daily allowance(RDA) for a certain vitamin = 45 mg

To find : Quantity of this vitamin in drink

Amount of vitamin new drink has = 130% of  (RDA)

= (130% of 45) mg

=  (1.3 x 45  mg  [ To convert percentage to decimal , we divide a number by 100]

=  58.5 mg

Therefore, Quantity of vitamin in drink = 58.5 mg
