Solve for x: 2x+1/3 + 1 = x-4/6
This is my last question.
Answer:
Hence, the value of "x" is -4.
Step-by-step explanation:
[tex]\sf \leadsto \dfrac{2x + 1}{3} + 1 = \dfrac{x - 4}{6}[/tex]
[tex]\sf \leadsto \dfrac{2x + 1 + 3}{3} = \dfrac{x - 4}{6}[/tex]
[tex]\sf \leadsto \dfrac{2x + 4}{3} = \dfrac{x - 4}{6}[/tex]
[tex]\sf \leadsto 6(2x + 4) = 3(x - 4)[/tex]
[tex]\sf \leadsto 12x + 24 = 3x - 12[/tex]
[tex]\sf \leadsto 12x - 3x = -12 - 24[/tex]
[tex]\sf \leadsto 9x = -36[/tex]
[tex]\sf \leadsto x = \dfrac{-36}{9}[/tex]
[tex]\sf \leadsto x = -4[/tex]
Hence, solved!!
Answer:
x=-4
Step-by-step explanation:
[tex] \frac{2x +1 }{3} + 1 = \frac{x - 4}{6} [/tex]
[tex] \frac{2x + 1 + 3}{3} = \frac{x - 4}{6} [/tex]

What is the answer to this math question
Answer:
11
Step-by-step explanation:
1.80m + 0.6s = 12.00
[substitute the value of m into the equation]
1.80×(3) + 0.6s = 12
5.4 + 0.6s = 12
[make s the subject of the formula]
0.6s = 12 - 5.4
0.6s = 6.6
[divide both sides of the equation by 0.6]
0.6s / 0.6 = 6.6 / 0.6
s = 11
To prove that 11 is correct
[substitute the value of m and s into the equation]
1.80m + 0.6m = 12.00
1.80×(3) + 0.6×(11) = 12.00
5.4 + 6.6 = 12.00
12.00 = 12.00

convert 150.55 decimal to binary
Answer:
10010110 . 100011₂
Step-by-step explanation:
A real number consists of two parts.
That is, ( 1 ) Integer part ( 2 ) fractional part
Let us take the given number as an example.
Here, 150 . 55 ← fractional part
↑
(integer part)
So, to make such a decimal number into a binary number you have to use a method like this.
First, you have to make the integer part a binary number.For that, you have to divide the integer part by 2 until it gets zero.Important thing is you have to write the remainders in each step.After that, you have to write the remainders from bottom to top.Now, let us consider the fractional part.To convert the fractional part into a binary number you have to multiply only the fractional part in each step by two.There you'll get an integer part before the fractional part. In this step, you have to write the integer part from top to bottom.Let us solve it now.
Integer part
2 |150
2 |75 - 0
2 | 37 - 1
2 | 18 - 1
2 | 9 - 0
2 | 4 - 1
2 | 2 - 0
2 | 1 - 0
0 - 1
∴ 150 ⇒ 10010110₂
Fractional part
| . 55 × 2
1 | . 10 × 2
0 | . 2 × 2
0 | . 4 × 2
0 | . 8 × 2
1 | . 6 × 2
1 | . 2
As this fractional part not getting the zero even we multiply by 2 continuously, we have to write an approximate value for this.

a basketball team sells tickets that cost $10, $20, or for VIP seats, $30. The team has sold 3241 tickets overall. It has sold 101 more $20 tickets that $10 tickets. The total sales are $59830. How many tickets of each kind have been sold?
Answer:
x = 1,213
y = 1,314
z = 714
Step-by-step explanation:
$10 = x
$20 = y
$30 = z
10x + 20y + 30z = 59,830
____________
Solving for x:
Since there 101 more $20 tickets than $10 tickets we are making the equation of:
y = x + 101
First equation (substitute the equation above for y)
x + (x+ 101) + z = 3,241
Subtract 101 from 3,241
2x + z = 3,140
Second equation (substitute y with 'x + 101 ')
10x + 20(x + 101) + 30z = 59,830
10x + 20x + 2,020 + 30z = 59,830
Subtract 2,020 from 59,830
10x + 20x + 30z = 57,810
Add 10x and 20x
30x + 30z = 57,810
Cancel out the 30's and divide 57,810 by 30
x + z = 1,927
Now solve using the first 2 equations
2x - z =3,140 = x + z = 1,927
Subtract z
2x = 3,140 = x + 1,927
Divide x
x = 3,140 = 1,927
Subtract 1,927 from 3,140
x = 1,213
____________________
Solving for y:
y = x + 101
y + 1,213 + 101
y = 1,314
____________________
Solving for z:
1,213 + 1,314 + z = 3,241 (Overall tickets sold)
2,527 + z = 3,241
Subtract 2,527 from 3,241
z = 714
____________________
Check math:
10x + 20y + 30z = 59,830
10(1,213) + 20(1,314) + 30(714) = 59,830

how do i solve xk=v-w solve for x
Answer:
x = (v-w)/k
Step-by-step explanation:
Step 1: Isolate x by dividing both sides of the equation by k.
[tex]\frac{xk}{k} = \frac{v-w}{k}[/tex] [tex]x = \frac{v-w}{k}[/tex]Therefore, the answer is [tex]x = \frac{v-w}{k}[/tex].
Answer:
x = [tex]\frac{v-w}{k}[/tex]
Step-by-step explanation:
xk = v - w ( isolate x by dividing both sides by k )
x = [tex]\frac{v-w}{k}[/tex]

7x – 2y = 18
—4x + 3y = –14
• (-2, 2)
• (1, 6)
• (4, 5)
• (2, - 2)
Answer:
(2, -2)
Step-by-step explanation:
Solve 7x - 2y = 18 for x:
[tex]7x - 2y = 18[/tex] [tex]7x - 2y + 2y = 18 + 2y[/tex] (Add 2y to both sides)[tex]7x = 2y + 18[/tex] [tex]\frac{7x}{7} = \frac{2y+18}{7}[/tex] (Divide both sides by 7)[tex]x = \frac{2}{7}y+\frac{18}{7}[/tex]Substitute 2/7y+ 18/7 for x in -4x + 3y = -14
[tex]-4x + 3y = -14[/tex] [tex]-4(\frac{2}{7}y+\frac{18}{7})+3y=-14[/tex] [tex]\frac{13}{7}y-\frac{72}{7}=-14[/tex] (Simplify both sides of the equation) [tex]\frac{13}{7}y-\frac{72}{7}+\frac{72}{7} =-14+ \frac{72}{7}[/tex] (Add 72/7 to both sides)[tex]\frac{13}{7}y=\frac{-26}{7}[/tex] [tex]\frac{13}{7}y*\frac{7}{13}=\frac{-26}{7} * \frac{7}{13}[/tex] [tex]y = -2[/tex]Substitute -2 for y in x = 2/7y + 18/7
[tex]x = \frac{2}{7}y + \frac{18}{7}[/tex] [tex]x = \frac{2}{7}(-2) + \frac{18}{7}[/tex] [tex]x = 2[/tex] (Simplify both sides of the equation)Given that x = 2 and y = -2, the point is: (2, -2)
Therefore, the solution is (2, -2).

A worker has job offers from two companies. The information below summarizes the job offer from each company.
Company A:
Starting salary of $31,000
Raise of $3000 each year
Company B:
Starting salary of $38,000
Raise of $2000 each year
Part A: Write an equation in terms of n years that can be used to determine the number of years when the salaries would be the same for both companies.
Part B: Use the equation you wrote in part A to determine the number of years it would take for the salaries to be the same for both companies. Use mathematics to support your answer.
Answer:
Part A: 31000 + 3000x = 38000 + 2000x; Part B: 7 years.
Step-by-step explanation:
x = number of years since start
For Company A, we have that salaryA(x) = 31000+3000x,
For Company Part B: salaryB(x) = 38000+2000x
We want x such that salaryA(x) = salaryB(x).
Thus,
31000 + 3000x = 38000 + 2000x (Answer to part A)
Subtracting 31000 from both sides of the equation implies that:
3000x = 7000 + 2000x.
Subtracting 2000x from both sides implies that:
1000x = 7000.
Then, dividing both sides of the equation by 1000 yields:
x = 7 years (Answer to part B)

can you add fractions with unlike denominators? if so what do you have to do.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.
To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
A bag contains
18
red balls and
4
blue.
What percentage of balls are red?
Answer:
81% of the balls are red
Step-by-step explanation:
If you want to find the percentage of balls that are red you will have to divide it by the total number of balls in the ball
18 red + 4 blue = 22 balls part (a)
18/22 = 9/11 part (b) simplify
9/11 * 100 part (c) multiply the fraction by a hundred to get the percentage
81.81 ~ 81% part (d) solve
Answer:
81 9/11%
Step-by-step explanation:
First add the number of red and blue balls together. 18 + 4 = 22
What is the number of red balls? It’s 18
We have to begin by writing this information as a fraction. 18 balls would be the numerator and the total of red and blue balls together, 22 will be the denominato. Now, we have the fraction, 18 (red) / 22 (total). To find the percentage, divide the numerator by the denominator. 18 divided by 22, which is 9/11. Now multiply 9/11 by 100, which gives you 81 9/11%.
Therefore, the answer is 81 9/11%.

→ 3p = 6
→ p = 6 ÷ 3
→ [ p = 2 ]
Hence, the value of p is 2.
