I need help finding the values

Answers

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x------> the number of minutes

y------> the depth in feet

In this problem the relationship between the variables, x, and y, represent a proportional variation

Remember that

A proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

step 1

Find the value of k

Let

$A(2,3)$ ------> see the given table

$k=y/x$ ----> substitute the values

$k=3/2=1.5$

The direct variation equation is equal to

$y=1.5x$

step 2

Complete the table

For $x=3\ min$

substitute the value of x in the equation and solve for y

$y=1.5(3)=4.5\ ft$

step 3

Complete the table

For $y=6\ ft$

substitute the value of y in the equation and solve for x

$6=1.5x$

$x=6/1.5=4\ min$

In the last basketball game, the panthers scored 63 points. This was seven times the number of points that Reilly scored. Write and solve an equation to find the number of points Reilly scored

Answers

9
In this question all you have to do is divide 63 by 7.

you would first have to do the opposite of seven times which would be division, this would lead to being 63÷7, with this your answer would be 9, you can also check your work by doing 7×9 and getting 63.

[120 + (12 ÷ 3 • 30)] ÷ 20 + 102

Answers

$([120 + ( (12.30)/(3) )])/(20) +102 ==> \n \n \n (120+(120))/(20) +102==> \n \n (240)/(20) +102=12+102==> \n \n 114 \n \n \framebox[1.1\width]{Good Luck !} \par$

You would take 12 divided by 3 to get 4. Take 4 times 30 to get 120. 120+120 is 240. 240 divided by 20 is 12. 12+102 is 114. 114 is your answer
