Let's say that s=spoons and f=forks.
According to this, we can say that:
{4s+3f=15
{4s+f=13
This is a system.
We can then use elimination to solve and isolate the variable:
(4s-3f=15)
- (4s+f=13)
We can then subtract and conclude that:
-4f=2
-f=1/2
f=-1/2
Angle 5x+7 is equal to the the sum of its remote interior angles, which we are given as x+15 and 6x-26. Therefore, 5x+7=x+15+6x-26. We will combine like terms to get 5x+7=7x-11. Move the 7x over to the other side by subtraction and the 7 to the other side by subtraction to get -2x = -18. That leaves us with an x value of 9. There you go!
Answer:
4.17% (nearest hundredth)
Step-by-step explanation:
percent change = [ (difference between initial value and final value) ÷ initial value] x 100
⇒ percent change = [ (50 - 48) ÷ 48 ] x 100 = 4.17% (nearest hundredth)
The two possible values are 1 and 0
