Answer:

x=20

Step-by-step explanation:

Ques5) x value is 20 because 3x+6x=180

=>9x=180

=> x=180/9

=> x=20

Ques6) 6x= 6*x which is equal to 6*20=120

Ques7) 3x=3*x which is equal to 3*20=60

This is correct because 120+20=180 which is a straight angle given in the question. Hope this helped, Thank you.

Write an eqation pf the line that passes through (-2,3) and is perpendicular to the line y= 2x - 1
Romashka [77]

Answer: x=1

Step-by-step explanation: Look at highlight_red%28+3%2Ax+%29-highlight_red%28+x+%29%2B2=4.

Eliminated similar terms highlight_red%28+3%2Ax+%29,highlight_red%28+-x+%29 replacing them with highlight_green%28+%283-1%29%2Ax+%29

It becomes highlight_green%28+%283-1%29%2Ax+%29%2B2=4.

Look at %28highlight_red%28+3+%29-highlight_red%28+1+%29%29%2Ax%2B2=4.

Added fractions or integers together

It becomes %28highlight_green%28+2+%29%29%2Ax%2B2=4.

Look at highlight_red%28+%28highlight_red%28+2+%29%29%2Ax+%29%2B2=4.

Remove unneeded parentheses around factor highlight_red%28+2+%29

It becomes highlight_green%28+2+%29%2Ax%2B2=4.

Look at 2%2Ax%2B2=highlight_red%28+4+%29.

Moved these terms to the left highlight_green%28+-4+%29

It becomes 2%2Ax%2B2-highlight_green%28+4+%29=0.

Look at 2%2Ax%2Bhighlight_red%28+2+%29-highlight_red%28+4+%29=0.

Added fractions or integers together

It becomes 2%2Ax%2Bhighlight_green%28+-2+%29=0.

Look at 2%2Ax%2Bhighlight_red%28+-2+%29=0.

Removed extra sign in front of -2

It becomes 2%2Ax-highlight_green%28+2+%29=0.

Look at highlight_red%28+2%2Ax-2+%29=0.

Solved linear equation highlight_red%28+2%2Ax-2=0+%29 equivalent to 2*x-2 =0

It becomes highlight_green%28+0+%29=0.

Result: 0=0

This is an equation! Solutions: x=1.

Calculate 12 x 15 by changing the numbers into friendlier numbers as we saw in the videos. Show how you work it out – write out
kondor19780726 [428]

Answer:

The product 12 × 15 in friendlier numbers is (10 + 2) × (10 + 5) = 180

Step-by-step explanation:

The parameter given are;

To 12 × 15 by changing the numbers into friendlier numbers

The product in 12 × 15 written with friendlier numbers (or in a simplified format can be given as follows;

12 × 15 = (10 + 2) × (10 + 5)

Which gives;

(10 + 2) × (10 + 5) = 10² + 10 × 5 + 2 × 10 + 2 × 5

From which we have;

10² + 10 × 5 + 2 × 10 + 2 × 5 = 100 + 50 + 20 + 10 = 180

Therefore;

12 × 15 = 180.

Blanca runs 8 laps around the track each day to train for an endurance race. She times each lap to practice her pacing for the r
Artist 52 [7]

Answer:

A graph shows lap time (seconds) labeled 82 to 98 on the horizontal axis and the number of laps on the vertical axis. 1 lap was 82 to 84 seconds.  4 laps were 84 to 86 seconds. 2 laps were 86 to 88 seconds. 4 laps were 88 to 90 seconds. 6 laps were 90 to 92 seconds. 5 laps were 92 to 94 seconds. 2 laps were 94 to 96 seconds. 0 laps were 96 to 98 seconds

Step-by-step explanation:

The given table is presented as follows;

\begin{array}{ccc}Day \ 1 \ lap \ times \ (seconds)&Day \ 2 \ lap \ times \ (seconds)&Day \ 3 \ lap \ times \ (seconds)\\83&87&85\\92&90&86\\91&92&91\\89&91&93\\94&92&91\\93&95&89\\88&90&88\\84&85&84\end{array}The number of laps in the range 82 to 84 seconds = 1

The number of laps in the range 84 to 86 seconds = 4

The number of laps in the range 86 to 88 seconds = 2

The number of laps in the range 88 to 90 seconds = 4

The number of laps in the range 90 to 92 seconds = 6

The number of laps in the range 92 to 94 seconds = 5

The number of laps in the range 94 to 96 seconds = 2

The number of laps in the range 96 to 98 seconds = 0

Therefore, the histogram that represents Blanca's lap times for the three days of practice is described as follows;

A graph shows lap time (seconds) labeled 82 to 98 on the horizontal axis and the number of laps on the vertical axis. 1 lap was 82 to 84 seconds.  4 laps were 84 to 86 seconds. 2 laps were 86 to 88 seconds. 4 laps were 88 to 90 seconds. 6 laps were 90 to 92 seconds. 5 laps were 92 to 94 seconds. 2 laps were 94 to 96 seconds. 0 laps were 96 to 98 seconds
