F + R = 2.75
2.125 + R = 2.75
R = 2.75 - 2.125
R = .625
Hope this helps :)
After attempting to determine the mass of a few objects, Lashandra realizes there must be something wrong with her formula. What is Lashandra's error? She should have multiplied by 2 instead of dividing by 2. She should have multiplied by K equals StartFraction one-half EndFraction m v squared.!!
Let the tickets be x and the snacks be y.
2x + 3y = 25 .... equation(1) *3 => 6x+9y = 75... (3)
3x + 4y = 35 ....(2) *2 => 6x + 8y= 70....(4)
on (3) - (4)
we get,
6x + 9y = 75
6x + 8y = 70
(-) (-) (-)
___________
y = 5
on putting value of y in (1),
2x + 3*5 = 25
=>2x= 25-15 => 2x = 10 =>x= 10/2 => x= 5
<span>hence , a movie ticket is $5 as well as a snack is $5</span>
Step-by-step explanation:
I don't see any numbers, so I just give you an example :
<u>1</u>1
every position in a number is worth 10 times the value of the position to its very right.
so, in e.g. 11
the left 1 is worth 10 times the value of the right 1.
x = 8, --- 12
I hope this helped :))))))))))))))))))
