Answer:
m∠XMN = 80°
Step-by-step explanation:
you know that:
4x + 5 + 6x - 10 = 145
solve for x:
10x - 5 = 145
10x = 150
x = 15
Use this information to solve for m∠XMN
6(15) - 10
90 - 10
80
m∠XMN = 80°
Answer:
1. x=2
2. x= 0.33
Step-by-step explanation:
1.So to start off you have a coefficient for 2 so you have to find what 2 to the power of 2 is =4 so then you have your new problem 4x+5=13 next you need to get 4x by itself so
-5 -5
then you have 4x=8. you divide by 4 on both sides
4. 4
so then you get x=2
2.So same here find what 3 to the power of 2 is =9
New equation 4x-1=9x+4x-4. Then combine like terms on the right you cant do it on the left because that is a separate part and those dont merge like terms so
9x+4x = 13x
new equation. 4x-1=13x-4
next subtract 4x on both sides
13x-4x=9x
new equation. -1=9x-4
next add 4 to both sides
-1+4= 3
new equation. 3=9x
so then divide 9 on both sides
3÷9= 0.33
x= 0.33
Hope this made sense and helps
Answer:
512 meters
Step-by-step explanation:
the rate or speed given to you is 32 meters per second
the time given to you is 16 seconds
to find the distance, you multiply your rate and time (not add)
multiplying would get you to 512 m/s
A) ( 25 / 100 ) * 100 = 25 m ;
b) ( 30 / 100 ) * ( 1205 / 100 ) = 36150 / 10000 = 3615 / 1000 = 3,615 km ≈ 3,62 km ;
c) ( 40 / 100 ) * 60 = ( 4 / 10 ) * 60 = 4 * 6 = 24 m^2 ;
d) 3 1 /3 = 10 / 3 ;
( 32 / 100 ) * ( 10 / 3 ) = 320 / 3 = 106,66 kg;
e) ( 1 / 10 ) ÷ 100 * 10 = ( 1 / 10 ) * ( 1 / 100 ) * 10 = 1 / 100 = 0,01 l ;
Good luck !
