This is true. The numbers being arranged differently in this does not mean it'll not equal each other.
5x-2+x=9+3x+10
6x-2=3x+19
3x=21
x=21/3
x=7
Answer:
Sorry need points for help
Step-by-step explanation:
400 = 45x + 30x
400 = 75x
5.333 = x
Lets test
45mph for 5.333 hours = 240 miles
30mph for 5.333 hours = 160 miles
240 + 160 = 400 miles apart.
The given proportion is expressed as
y/5 = 7/8
If we crossmultiply, it becomes
y * 8 = 7 * 5
8y = 35
y = 35/8
y = 4.375
Rounding to the nearest tenth,
y = 4.4
