Answer: B, C, D
Step-by-step explanation:
6x + 1 - (3x -1)
=> 6x + 1 - 3x + 1
=> 3x + 2
So Answers: B, C, D
The expression that should be equivalent to 6x + 1 - (3x - 1) is option B, C, D.
Calculation of the expression:Since the equation is 6x + 1 - (3x - 1)
So,
6x + 1 - (3x -1)
6x + 1 - 3x - (-1)
6x + 1 -3x + 1
And, 3x + 2
Therefore, we can conclude that The expression that should be equivalent to 6x + 1 - (3x - 1) is option B, C, D.

solve the simultaneous Equation
3/x- 4/y= 1/3
Answers
Answer:
a simultaneous equation is a set of equations. you need at least another equation.
Answer:
Step-by-step explanation:
Let's solve for x.
3x−4y= 1/ 3
Step 1: Add 4y to both sides.
3x−4y+4y= 1/ 3 +4y
3x=4y+ 1/ 3
Step 2: Divide both sides by 3.
3x/ 3 = 4y+ 1/ 3
3 x= 4/ 3 y+ 1/ 9
Answer:
x= 4/ 3 y+ 1/ 9
Let's solve for y.
3x−4y= 1/ 3
Step 1: Add -3x to both sides.
3x−4y+−3x= 1/ 3 +−3x
−4y=−3x+ 1/ 3
Step 2: Divide both sides by -4.
−4y/ −4 = −3x+ 1/ 3
−4 y= 3/ 4 x+ −1/ 12
Answer:
y= 3/ 4 x+ −1/ 12

Answers
24 is 3/4% of what number
Answers
Answer:
32
Step-by-step explanation:
Alright, so think of the "what number" as x in this case. (Or any number/symbol you choose.)
So our simple equation looks something like this:
[tex]24= x *\frac{3}{4}[/tex]
So, to find out what the "what number" would be we'd flip the fraction around/find the reciprocal and multiply 24 by it. That gives us "x" or the number we're missing.
So: [tex]24 * \frac{4}{3} = x[/tex]
Doing the simple math we get:
[tex]24 * \frac{4}{3} = 32[/tex].
32 is your answer.
Hope this helps and have a nice day! Sorry I'm not great at explaining it!

Raju covers a certain distance in 1 hour and sham covers the same distance in 2 hours , who travels in a higher speed?
Answers
Answer: Raju travels at a higher speed.
Step-by-step explanation:
[tex]Speed =\dfrac{Distance}{Time}[/tex]
Speed inversely proportional to time.
As time taken to cover a particular distance decreases the speed will increase.
Raju covers a certain distance in 1 hour.
Sham covers the same distance in 2 hours.
1< 2
Thus Raju travels at a higher speed.

Step-by-step explanation:
Number 1 is going to be
[tex]a^{2} + b^{2} = c^{2}[/tex] because it's a right triangle
So
[tex]24^{2}[/tex] + [tex]7^{2}[/tex] = [tex]c^{2}[/tex]
625 = [tex]c^{2}[/tex]
c = 25 mile
Number 2 uses the same process, but changing to using C instead of A
a^2 = c^2 - b^2
a^2 = 625 - 225
a = \sqrt(400)
a = 20m

We need to find an answer for the "no taxi" section. And we have the total and the "yes taxi" section. So, the "yes taxi" section + the "no taxi" section gives you the total. Another way of saying this is total - "yes taxi" = "no taxi"125 - 30 = 95No Bus Column:
We need to find the total of the "yes taxi" section and the "no taxi" section. So, if we add those two sections together, we'll get the total90 + 185 = 275Total column:
So, this column is really simple to fill out. All we're doing it adding our answers above to get one answer in each section."Yes Taxi" section: 30 + 90 = 120"No Taxi" section: 280Total section: 125 + 275 = 400We could have also done the total section by adding together 120 and 280, but we would get the same answer, anyway.I hope this helps!
