Somebody tell me the answer to this please

When using the box method, it's really helpful to write equations. For example in this equation, let's set the value on top of the top left box (left of the "1") as x.

So,

k * x = 5k²

Divide both sides by k

x = 5k

Set the other unknown factor (the one below "k") as y.

So,

y * 1 = -7

y = -7

Now, solve for the missing products:

k * 1 = k

5k * (-7) = -35k

I hope this helps! Feel free to ask any questions!

Answer:

300K

Step-by-step explanation:

T = t + 273 °C

T is absolute temperature

t = given temperature (27°C in this case)

Hence T = 27 °C + 273 °C (standard temperature)

T = 300K (since absolute temperature is measured in K from the question's preamble)

Answer:

A) 3/50

Step-by-step explanation:

2 + 5 + 3 = 10

Probability of drawing red = 2/10 = 1/5

Probability of drawing blue = 3/10

[tex]\frac{1}{5} *\frac{3}{10}[/tex]

3/50

Answer:

B. 6 hours and 40 mins

Step-by-step explanation:

Create a proportion where x is the amount of time to hike the entire 8 miles.

Represent the time in minutes:

[tex]\frac{130}{2.6}[/tex] = [tex]\frac{x}{8}[/tex]

Cross multiply and solve for x:

2.6x = 1040

x = 400

Convert this to hours:

400/60

= 6.67 (6 hours and 40 mins)

So, the correct answer is B. 6 hours and 40 mins

Answer

The blue one, the purple one, and the green one that's in the bottom right hand corner

Step-by-step explanation:

The rectangle and Parallelogram has pair of parallel sides.

Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions

Rectangle is a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.

and a parallelogram is a simple quadrilateral with two pairs of parallel sides.

In the given figures, The rectangle which is in blue color has pair of parallel lines and Parallelogram which are pink and in green color at corner has pair of straight lines.

Hence, the rectangle and Parallelogram has pair of parallel sides.

Answer:

y=6x+3

Step-by-step explanation:

1.6x-y=1  solve for y

-y=-6x+1 divide bot sides by -1

y=6x-1

slope is 6

the slopes of parallel lines are equal

y-(-3)=6(x-(-1))

y+3=6(x+1)

y+3=6x+6

y=6x+6-3

y=6x+3

Answer:

(0,3)

Step-by-step explanation:

The total number of students in the school will be 675.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that sixty-eight per cent of valley creek school students attend this year's homecoming dance if 459 students attend the dance.

The number of students will be calculated as,

68% ⇒ 459

1% ⇒ 459 / 68

100% ⇒ (459 x 100 ) / 68

100% ⇒ 675 students

Therefore, the total number of students in the school will be 675.

Answer:

2.6

Step-by-step explanation:

Answer:

baseball cap = $28

t-shirt =  $25

Step-by-step explanation:

Olivia: t +5b = 165

Marco: t + 4b = 137

isolate t in Olivia's equation

t = 165 - 5b

plug t into Marco's equation

165 - 5b + 4b = 137

165 - b = 137

b = 28

plug b into either equation

t + 4b = 137

t + 4(28) = 137

t + 112 = 137

t = 25
