Answer:
Step-by-step explanation:
Equations
7x + 3y = 4z
<em>Second equation</em>
x + y = z Multiply the entire equation by 4
4[x + y = z] Now distribute the 4 through the equation
4x + 4y = 4z Both equations = 4z. Equate the lefts.
<em>Third equation </em>
7x+3y = 4x + 4y Subtract 3y from both sides
7x + 3y -3y = 4x + 4y -3y
7x = y + 4x Subtract 4x from both sides
7x - 4x = y + 4x - 4x Combine
3x = y
Answer: 3x = y
Answer:
It will
Step-by-step explanation:
A meter is about 3,3 feet so 2,1 meters is 6,8 feet meaning that yes it will fit.
Answer: y= sin x+2
Step-by-step explanation:
There would be 0.07923 probability to get 4 aces.
<h3>What is probability ?</h3>
Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Total number of cards in deck = 52
Total number of aces = 4
When 5 cards are chosen randomly,
The probability to get 4 aces
= 1/52+1/51+1/50+1/49+0
Since, at 5th time there will be no ace remains, so probability would be 0.
= 0.01923+0.01960+0.0200+0.0204
=0.07923
