Answer:
2y-x-1
Step-by-step explanation:
use zero property
(-2x. +2x) =0
=6y-x+5-4y-6
collect like terms
6y-4y=2y
=2y-x+5-6
calculate the difference
+5-6=-1
=2y-x-1
good day :)
Answer:
30 and 40
Step-by-step explanation:
That L-shaped sidewalk and the shortcut through the grass form a triangle, a rectangle triangle.
The shortcut represents the hypotenuse, and the two other sides sum up to 70 yards.
What's the relationship between the hypotenuse of a rectangle triangle and the other sides?
c² = a² + b²
So, we have here:
50² = a² + b²
50² = 2500
What are 2 numbers that are square numbers and added together make 2500? (think 25 it's easier and same principle)
How about 1600 and 900?
So, 2500 = 1600 + 900, or 50² = 40² + 30²
so the two sides legs of the sidewalk measure 30 and 40 yards.
Answer:
-1.81 is the least and 1 3/4 is the greatest
Step-by-step explanation:
1 3/4 is also 1.75 -1 4/5 is also -1.8
Ordered from least to greatest:
-1.81, - 1 4/5, -1.3, 1 3/4
Answer:
a) $170
b) 12
Step-by-step explanation:
A = 250 - 20t
where A is Jina's account balance and t is the number of trips she takes.
a) If Jina takes 4 trips, then t = 4.
Substitute t = 4 into the given equation:
A = 250 - (20 x 4)
= 250 - 80
= 170
So Jina has $170 left in her account after 4 trips.
b) The calculate the maximum number of trips Jina can take without running out of money, set A to zero and solve for t:
when A=0: 0 = 250 - 20t
Add 20t to both sides: 20t = 250
Divide both sides by 20: t = 12.5
Therefore, Jina can take 12.5 trips. However, she can't take a half-trip so we should round the number down to 12 trips (as after 12 trips she will only have enough money left for half a trip).
So, the largest number of trips Jina can take without running out of money is 12.
