PLS HELP ASAP!

Masha bought red, green, and yellow balloons for a party. She bought 40 red balloons. The number of green balloons Masha bought is 3/5 of the number of red balloons. The number of green balloons is also 2/3 of the number of yellow balloons. while being inflated, 1/20 of the red balloons, 1/12 of the green balloons, and 1/36 of the yellows balloons popped. The remaining balloons were used as decoration. What part of all the balloons Masha purchased to decorate the party?

Answer:

[tex]\frac{35}{2}[/tex] - [tex]7n[/tex]

Step-by-step explanation:

7/1 − 3( 7/3n − 7/2 )

Anything divided by one gives itself.

7 - 3 ( [tex]\frac{7}{3}n - \frac{7}{2}[/tex])

Use the distributive property to multiply −3 by  [tex]\frac{7}{3}n - \frac{7}{2}[/tex])

7 - 3 × ([tex]\frac{7}{3}[/tex][tex]n[/tex] - 3 (-[tex]\frac{7}{2}[/tex])

Multiply −3 times [tex]\frac{7}{3}[/tex]

7 - 7n - 3 (-[tex]\frac{7}{2}[/tex])

Express -3 (-[tex]\frac{7}{2}[/tex]) as a single fraction.

7 - 7n + [tex]\frac{-3(-7)}{2}[/tex]

Multiply −3 and −7 to get 21.

7 - 7n + [tex]\frac{21}{2}[/tex]

Convert 7 to fraction [tex]\frac{14}{2}[/tex]

[tex]\frac{14}{2}[/tex] - 7n +  [tex]\frac{21}{2}[/tex]

Since [tex]\frac{14}{2}[/tex] and [tex]\frac{21}{2}[/tex] have the same denominator, add them by adding their numerators.

[tex]\frac{14 + 21}{2} - 7n[/tex]

Add 14 and 21 to get 35.

[tex]\frac{35}{2} - 7n[/tex]

Answer:

B: 0.50x + 3 = 4.50

Step-by-step explanation:

James needed an additional 3 scoops so the x would have to be on $0.50. the $3 is what the cone cost so it has to be with the scoop price. $4.50 is the total price of the ice cream so that would be on the other side of the equal sign, resulting in 0.50x + 3 = 4.50

Answer:

a. [tex]4^2[/tex]

b. 16

Step-by-step explanation:

The area of a square is equal to the side length squared. Normally, the area of a rectangle is length times width but since all sides are equal in a square it is just the side times the side. This can be simplified to side length squared.

Since the side length is 4 the exponent form of the area is simply 4 squared or [tex]4^2[/tex].

Then, compute this by multiplying 4*4. This equals 16 cms square.

I'm pretty sure the answer to y=−x. Write equation for (8,2) is y=x-6. The opposite of the x is -8, hence, (-8,2) is y=-x-6 is the answer

1. The equation of the line which is parallel and goes through the point (-8, 2) is,

y = x + 10

2. The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

What is Equation of line?

The equation of the line in slope-intercept form is expressed as:

y - y₁ = m(x - x₁)

where: m is the slope.

and (x₁, y₁) is the point on the line.

1. Given that;

Equation of the line as y = -x

Get the slope of the line,

y = -x

m = -1

Since, The required line is parallel to this line,

So, the required slope will be -1

Now, Get the required equation as,

y - y₁ = m(x - x₁)

y - 2 = 1 ( x - (-8) )

y - 2 = x + 8

y = x + 8 + 2

y = x + 10

Hence, The equation of the line which is parallel and goes through the point (-8, 2) is,

⇒ y = x + 10

2.  Given that;

Equation of the line as y = -x

Point as (8, 2)

Get the slope of the line,

y = -x

m = -1

Since, The required line is parallel to this line,

So, the required slope will be -1

Now, Get the required equation as,

y - y₁ = m(x - x₁)

y - 2 = 1 ( x - 8 )

y - 2 = x - 8

y = x - 8 + 2

y = x - 6

Hence, The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

Thus,

1. The equation of the line which is parallel and goes through the point (-8, 2) is,

y = x + 10

2. The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

Answer:

(1,2)

Step-by-step explanation:

6 km/h going north for 20 mins would be 1/3 of an hour so 1/3 of 6. This would mean they walked 2 kilometers north. That's your y-coordinate. They walked 6 kilometers an hour going east for 10 mins. 10 mins is 1/6 of an hour and 1 is 1/6 of 6. So 1 is your x-coordinate. You put the numbers in as (x, y).

If the swimming pool is at the origin (0, 0) then the position of the ice cream shop is (1,2) and this can be determined by using the unitary method and also by using the formula of speed.

Given :

The following steps can be used in order to determine the position of the ice cream shop:

Step 1 - Remember 1 hour is equal to 60 minutes.

Step 2 - If one hour is equal to 60 minutes then in 20 minutes there are:

[tex]\rm \dfrac{20}{60}=\dfrac{1}{3}\;hour[/tex]

Step 3 - If one hour is equal to 60 minutes then in 10 minutes there are:

[tex]\rm \dfrac{10}{60}=\dfrac{1}{6}\;hour[/tex]

Step 4 - Determine the distance travel in the north which gives the y-coordinate.

[tex]\rm Distance = 6\times \dfrac{1}{3}=2\;Km[/tex]

Step 5 - Determine the distance travel in the east which gives the x-coordinate.

[tex]\rm Distance = 6\times \dfrac{1}{6}=1\;Km[/tex]

So, the position of the ice cream shop is (1,2).

?

Step-by-step explanation:

Expressions are used to show relationships between variables and constants

The expression is given as:

[tex]\mathbf{\frac a8 + 6b}[/tex]

In the above expression, a/8 and 6b are added.

So, the expression [tex]\mathbf{\frac a8 + 6b}[/tex] is a sum

In [tex]\mathbf{\frac a8 }[/tex], a is divided by 8.

So, the term [tex]\mathbf{\frac a8}[/tex] is a quotient

Lastly, in 6b; 6 is multiplied by b.

So, the term 6b is a product.
