Answer:

<u><em>T=1 if i can have brainliest that would be great</em></u>

Step-by-step explanation:

16-2t=t+4t+9

16-2t=5t+9

16-2t-16=5t+9-16

-2t=5t-7

-2t-5t=5t-7-5t

-7t=-7

{-7t/-7}={-7/-7}

t=1

Answer:

t=1

Step-by-step explanation:

16-2t=t+9+4t

Combine like term

16-2t = 5t+9

Add 2t to each side

16-2t +2t= 5t+2t+9

16 = 7t+9

Subtract 9 from each side

16-9 = 7t+9-9

7 = 7t

Divide each side by 7

7/7 = 7t/7

1=t

-43/100 I think, since 43 doesn’t have any factors other than 1 and itself

Hope this helps :)

Polly buys 14 cupcakes for a party. The bakery puts them into boxes that hold 4 cupcakes each.

Temka [501]

Answer:

Part a) The number of boxes needed will be 4

part b) The fraction of the box that is empty is $\frac{1}{2}$

Part c) Are needed 2 cupcakes to fill the last box

Step-by-step explanation:

Part a) How many boxes will be needed for Polly to bring all the cupcakes to the party?

To find out the number of boxes needed, divide the total number of cupcakes by 4 (maximum number of cupcakes that fit in each box).

$\frac{14}{4}=3.5\ box$

Round up

The number of boxes needed will be 4

Part b) If the bakery completely fills as many boxes as possible, what fraction of the last box is empty?

we know that

The maximum number of cupcakes per box is 4

The first three boxes have 4 cupcakes

The last box has

$14-3(4)=2\ cupcakes$

The fraction of the box that is empty is equal to the number of cupcakes missing to fill the box divided by the cupcake capacity of the box

$\frac{2}{4}=\frac{1}{2}$

Part c) How many more cupcakes are needed to fill this box

Subtract the number of cupcakes in the box from the cupcake capacity of the box

The last box has 2 cupcakes

The cupcake capacity of the box is 4

$4-2=2\ cupcakes$

therefore

Are needed 2 cupcakes to fill the last box

Find the slope of the line perpendicular to the line graphed below. MUST BE IN ITS SIMPLEST FORM.

NNADVOKAT [17]

The slope of the line perpendicular to the line seen in the picture is - 2 / 3.

<h3>How to determine the slope of a line perpendicular to another line</h3>

The slope of a function is determined by the secant line formula and is defined by the following expression:

m = Δy / Δx (1)

Where:

Δx - Change in the independent variable.
Δy - Change in the dependent variable.
m - Slope of the line.

Besides, by analytical geometry, the slope of a line perpendicular to another line is equal to:

m' = - 1 / m

If we know that Δx = 2 and Δy = 3, then the slope of the line perpendicular to the line seen in the picture is:

m = 3 / 2

m' = - 1 / (3 / 2)

m' = - 2 / 3

The slope of the line perpendicular to the line seen in the picture is - 2 / 3.
