If m1=2x° and m3=3x° what is m1

olga_2 [115]

Answer:

Step-by-step explanation:

Using the angle addition postulate

angle 1+angle 2+angle 3=180

Angle 2 is 90 degrees,

Angle 1 is 2x degrees

Angle 3 is 3x degrees

Plug this into equation

$2x + 90 + 3x = 180$

$5x + 90 = 180$

$5x = 90$

$x = 18$

Plug 18 into 2x

$2(18) = 36$

What value of x is in the solution set of 3(x – 4) ≥ 5x + 2? –10 –5 5 10

emmasim [6.3K]

Answer:

The value of x is in the solution set of 3(x – 4) ≥ 5x + 2 is -10

Solution:

Need to determine which value of x from given option is solution set of 3(x – 4) ≥ 5x + 2

Lets first solve 3(x – 4) ≥ 5x + 2

3(x – 4) ≥ 5x + 2

=> 3x – 12 ≥ 5x + 2

=> 3x – 5x ≥ 12 + 2

=> -2x ≥ 14

=> -x ≥ 7

=> x ≤ -7

All the values of x which are less than or equal to -7 is solution set of 3(x – 4) ≥ 5x + 2. From given option there is only one value that is -10 which is less than -7

Hence from given option -10 is solution set of 3(x – 4) ≥ 5x + 2.

Molly's town voted on a new speed limit. Out of 38 votes, 19 were in favor of the new speed limit. What percentage of the votes

RUDIKE [14]

Answer:

Percentage of votes in favour of new speed limit=50%

Step-by-step explanation:

There was a voting in Molly's town to set a new limit for the speed attained by a vehicle.

In Molly's town,

Number of votes recorded=38

Number of votes in favour of the new speed limit=19

We have to find the percentage of votes in favour of the new speed limit.

For that,the percentage of votes in favour= $\frac{votes in favour of new speed limit×100}{total votes}$

Percentage of votes in favour= $\frac{19*100}{38}$

Percentage of votes in favour=50%
