Answers

Answer 1

Answer: 129,407
12 ten thousands is 120,000
8 thousand is 8,000
14 hundreds is 1,400
there are no tens
7 ones is 7
so 120,000+8,000+1,400+7=129,407

Tyler is thinking of a number that is divisible by 2 and by 3. By which of the following numbers must Tyler's number also be divisible?

Answers

Tyler's number also divisible of multiples of 6.

What is division?

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Tyler is thinking of a number that is divisible by 2 and by 3.

Co-prime numbers include the numbers 2 and 3.

As a result, if a number can be divided by 2 and 3,

it must also be divided by their product, or 6, which is 6.

All the multiples of 6 can be divided by 2 and 3.

Therefore, all the multiples of 6 can be divided by 2 and 3.

What is the equation of the line that passes through the point (3, 0) and is perpendicular to the line 2x – y = 5?

Answers

Answer:

$\large\boxed{y=-(1)/(2)x+(3)/(2)}$

Step-by-step explanation:

$\text{Let}\ k:y=_1x+b_1\ \text{and}\ l:y=m_2x+b_2.\n\nl\ \perp\ k\iff m_1m_2=-1\to m_2=-(1)/(m_1)\n============================\n\n\text{We have}\ 2x-y=5.\n\n\text{Convert to the slope-intercept form y = mx + b:}\n\n2x-y=5\qquad\text{subtract 2x from both sides}\n\n-y=-2x+5\qquad\text{change the signs}\n\ny=2x-5\to m_1=2\n\n\text{Therefore}\ m_2=-(1)/(2).$

$\text{The equation of the searched line:}\ y=-(1)/(2)x+b.\n\n\text{The line passes through }(3,\ 0).\n\n\text{Put the coordinates of the point to the equation.}\ x=3,\ y=0:\n\n0=-(1)/(2)(3)+b\n\n0=-(3)/(2)+b\qquad\text{add}\ (3)/(2) \text{to both sides}\n\nb=(3)/(2)$

The ratio of boys to girls of a class is 3 to 4. If there are 42 students, how many of them are boys? Show your work.

Answers

Answer:

There would be 18 boys.

Step-by-step explanation:

If the ratio of boys to girls is 3:4 that means in a classroom of 7 people there would be 3 boys and 4 girls. So all you do is multiply 3 boys by 6 (18) and 4 girls by 6 (24) cuz 7*6=42 which means that there would be a total of 42 students with 18 boys and 24 girls.

HOPE I HELPED!!!

well if x = 3y - 2, then everywhere u see and x remember it equals 3y - 2
so (3y - 2) - 4y = 5 then u distribute
-3y + 2 - 4y = 5 then combine the y's
-7y + 2= 5 then subtract 2 from each side
-7y = 3 then divide -7 on both sides
y = 3/-7
x = -3.28
