Answer:
x=7.5
Step-by-step explanation:
To solve this, cross multiply
3/4=x/10
4*x=3*10
4x=30
Divide by 4 on both sides
Hope this helps! :)
3/4 is 75% so therefore x/10 has to be the same
75% of 10 is 7.5
So therefore x=7.5
13.5
?=4
?*(3+2)=12+8
?(5)=20
20/5=4
4*(5)=20
20=20
Please refer to the above attachment
m = -7
1) expand: 2/9m-16/9=2/3m+4/3
2) add 16/9 to both sides:
2/9m-16/9+16/9=2/3m+4/3+16/9
3) simplify: 2/9m=28/9+2/3m
4) subtract 2/3 m from both sides:
2/9m-2/3m= 28/9+2/3m-2/3m
5) simplify: -4/9m=28/9
6) m=-7
