Answer:
5x + 4
Step-by-step explanation:
-five times a number would be 5x
-adding four would by +4
(3/7)-(1/14)=(6/14)-(1/14)=5/14
use LCD to get a like denominator, then just subtract
1) "Subtract -7a+1 from 7+a" means -7a+1 is getting taken away from 7+a, so this can be mathematically expressed as:
Starting expression: (7+a)-(-7a+1)
Distributive property with negatives: 7+a+7a-1
Combine like terms: 6+8a
So the answer for the first one is 6+8a
2) "Subtract -4v-2 from -2-5v" means -4v-2 is getting taken away from -2-5v, so this can be mathematically expressed as:
Starting expression: (-2-5v)-(-4v-2)
Distributive property with negatives: -2-5v+4v+2
Combine like terms: -v
So the answer for the second one is -v
Hope these explanations are clear.
Answer:
PERIMETER=Y+2Y+11+-3Y-9+Y^2+5Y-1+6Y^2
=7Y^2+4Y+1
Compose an equation
2/5x=3/20
Then solve
8/20x=3/20
8x=3
x=3/8
I might be wrong
