Answer:
Let Tom's cards = x
Equation:
Neils Cards = x + 83 (Neil has 83 more cards)
x + 83 = 517 (Tom has 83 cards less than Neil)
x = 434
Answer:
1/4
Step-by-step explanation:
To find the roots of the expression, factor the expression by GCF.

The roots are the factors set equal to 0 and solved for x.
2x = 0
x=0
4x-1 = 0
x = 1/4
The sum is the addition of the two roots 0 + 1/4 = 1/4
Answer:
x =6
Step-by-step explanation:
17x + 8 + 66 + 74 +110 = 360
17x + 258 =360
17x = 360 -258
17x =102
x =6
Answer:
Time at which the hammer reaches the ground is 2.3 seconds.
Step-by-step explanation:
We are given the formula as,
.
It is known that, when height i.e.
meter, then velocity
m/sec.
So, we get the formula as,
.
Now, when the hammer hits the ground, the height
meter.
Thus, we have,

⇒ 
⇒ 
⇒ 
i.e. t= ±2.3 sec
Since, time cannot be negative.
So, t= 2.3 sec
Hence, the time at which the hammer reaches the ground is 2.3 seconds.
