Answer:
3
Step-by-step explanation:
In a slope intercept linear equation, the slope is always the number in front of the x value in an equation like y = mx + b.
So the slope is the 3 in front of the x value.
Step-by-step explanation:
4.5x-2.3=6.7 (add 2.3 so no number in the equation)
6.7+2.3 is 9
4.5x=9 (divide by 4.5 as it's 9 is divisible by 4.5
9/4.5 is 2
X=2
put it back into the equation
4.5*2 is 9
9-2.3 is 6.7
Therefore X=2
Answer:
<h2>x=3/2, y=4</h2>
Step-by-step explanation:
3y=6x+3
solve by substitution for 3y=6x+3
3y=4x+6
6x+3=4x+6
6x-4x=6-3
2x=3
<h2>x=3/2</h2>
3y=6x+3 ⇒ y=6x/3 + 3/3 ⇒ y=2x+1
y=2x+1 ( substitute x=3/2)
y=2(3/2)+1
y=3+1
<h2>y=4</h2>
Heya friend,
------------------------------------------------------
Let the digits at ones place be x. Then,
the digits at tens place = (8-x)
Original number = 10(8-x) + x
= 80 - 10x + x
= 80 - 9x
On interchanging the digits
new number obtained = 10x + 8-x
= 9x + 8
According to question,
New number - Original number = 18
9x + 8 - (80-9x) = 18
=> 9x + 8 - 80 + 9x = 18
=> 18x - 72 = 18
=> 18x = 18 + 72
=> 18x = 90
=> x = 90/18
=> x = 5
Hence, the digits at ones place is 5.
The digits at tens place = (8-5) = 3.
So, the original number is 35 and the new number is 53.
Thanks
