I really need help on geometry

Answers

Answer 1

Answer: For example, exc. 15.

x + y = 10 and 6/x = 9/y; You need y!

=> x = 10 -y and 9x = 6y => 9(10-y) = 6y => 90 - 9y = 6y => 15y = 90 => y = 6.

The scatter plot shows a hiker's elevation above sea level during a hike from the base to the top of a mountain. The equation of a trend line for the hiker's elevation is y equals=9.069.06xplus+651651, where x represents the number of minutes and y represents the hiker's elevation in feet. Use the equation of the trend line to estimate the hiker's elevation after 175 minutes.

If the 6 in 4,563 was changed to 9 by how much would the value change

Answers

If the 6 was changed to a 9, then the value of 60 would be changed to a value of 90, since the 6 is in the 10's column.

That an increase in value of 30.

Julia enjoys shooting paper balls into the wastebasket across her office. She misses the first shot 50% of the time. When she misses on the first shot, she misses the second shot 20% of the time. What is the probability of missing two shots in a row

Answers

First, convert the percentages into fractions. Since Julia misses 50% of her first shots, she misses 1/2 of her first shots. Since she misses 20% of her second shots (after missing the first one), she misses 1/5 of her second shots.

To find the probability of missing two shots in a row, multiply the two fractions together:

1/2 x 1/5 = 1/10

1/10 correlates to 10%. So, Julia has a 10% probability of missing two shots in a row.

Answer:

10%

5x – 4 = x - 16
solve the equation

Answers

Answer:

x = - 3

Step-by-step explanation:

Given

5x - 4 = x - 16 ( subtract x from both sides )

4x - 4 = - 16 ( add 4 to both sides )

4x = - 12 ( divide both sides by 4 )

x = - 3

Answer:

$\huge{ \fbox{ \sf{x = -3}}}$

Step-by-step explanation:

$\star{ \sf{ \: 5x - 4 = x - 16}}$

$\text{Step \: 1 \: : \sf{ \: Move \: x \: to \: left \: hand \: side \: and \: change \: its \: sign.}}$

$\hookrightarrow{ \sf{5x - x - 4 = - 16}}$

$\text{Step \: 2 \: : \sf{ \: Move \: 4 \: to \: right \: hand \: side \: and \: change \: its \: sign.}}$

$\hookrightarrow{ \sf{ 5x - x = - 16 + 4}}$

$\text{Step \: 3 \: : \sf{Collect \: like \: terms}}$

$\hookrightarrow{ \sf{ 4x = - 16 + 4}}$

$\text{Step \: 4 \: : \sf{Calculate}}$

$\text{ \underline{Remember! : }} \sf{ \: The \: \: negative \: and \: positive \: integers \: are \: always \: subtracted \: but \: posses \: the \: sign \: of \: the \: bigger \: integer.}$
