what is the21st term of -3,2,7​

Answers

Answer 1

Answer:

102

Step-by-step explanation:

The first step is to find out how to find the next number in the term.

In this we can see that to get to the next number in the term we need to add 5.

The easiest way to figure out the 21st term of this, would be to multiply 5×21. This is equal to 105.

But since we started at three less than 5, we need to subtract 3 from 105. 105-3=102.

The 21st term is 102.

help!! Find the equation of the line shown ​

Answers

Answer:

[tex]\boxed{\bold{\huge{\boxed{y = 2x}}}}[/tex]

Step-by-step explanation:

Slope(m):

To find the slope , we need to take any two coordinates from the line.

The coordinates are (0,0) and (5,10)

Slope = [tex]\sf \frac{rise}{run}[/tex]

Slope = [tex]\sf \frac{y2-y2}{x2-x1}[/tex]

Slope = [tex]\frac{10-0}{5-0}[/tex]

Slope = [tex]\frac{10}{5}[/tex]

Slope = 2

Y-intercept(b):

Y-intercept is the point where x = 0 and that point is the origin.

So, y-intercept = 0

Slope-intercept equation:

[tex]\sf y = mx+b[/tex]

Where m = 2 and b = 0

[tex]\sf y = 2x+0[/tex]

[tex]\sf y = 2x[/tex]

M is the midpoint of segment AB and M (-4,-5) and A (-2,-9) find the endpoint B.
(-6, -1) b) (4,-1) c) (-2,4) d) (4,2)

The midpoint of a line segment divides a line segment into two equal parts. (T/F).

Answers

Answer:

(-6, -1)

Yes, the midpoint of a line segment divides the segment into two equal parts.  True.

Step-by-step explanation:

Going from A(-2, -9) to M(-4, -5), x decreases by two units from -2 to -4; if we now go from M(-4, -5) to B, we expect that x will decrease by two more units, from -4 to -6.  Thus, the x-coordinate of B is -6.

y increases by 4 from -9 to -5 (4 units) under the same circumstances.  To find the y-coordinate of B, we add 4 to -5, obtaining y = -1.

The endpoint B is thus (-6, -1).

2/5 as a decimal show all work

Answers

Answer:

0.4

Step-by-step explanation:

to convert from a fraction to a decimal, we first have to make the denominator 100

we know that 5 goes into 100 20 times ;

100 ÷ 5 = 20 ;

then we have to multiply the numerator by 20 as well because we have multiplied the bottom by 20 ;

[tex]\frac{2}{5}[/tex] [tex](\frac{20}{20})[/tex]

2 x 20 = 40 ;

= [tex]\frac{40}{100}[/tex]

then to convert this into a decimal, divide the numerator by the denominator

40  ÷ 100 = 0.4

If LMP = (6x+5), NMP = (4x +18) and NML = 163°, find the measure of PMN. im sorry i dont understand geometry at all can someone help?

Answers

Answer:

PMN = 74°

Step-by-step explanation:

1. 6x + 5 + 4x + 18 = 163°

2. Combine like terms

3. 10x + 23 = 163°

4. Subtract 23 from both sides.

5. 10x = 140°

6. Divide 10 from both sides.

7. x = 14°

8. Now substitute the x in the equation for PMN with 14.

9. 4(14) + 18

10. Simplify

Go with B I did the problem

Answer:

what is the answer?

Step-by-step explanation:

Please I need help....

Answers

Answer:

1. D

"n" represents the figure. For example, the equation for figure 3 would be [tex]\frac{3(3+1)}{2}[/tex] which is equal to 6 (the amount of blocks in the figure).

2. D

In the sample equations, the 9 represents figure 9. There are consistently 3 blocks in each row with an additional block at the top of the figures. So, the equation for figure 4 would be 1+(3x4) which is equal to 13. Therefore, the equation for figure 9 would be 1+(3x9).

3. A

P represents the perimeter and the n represents the figure number (like in question 1). The correct equation for the pattern would be P=4n+8. To check it, we can plug the numbers from figure 2. The equation would look like this: 16=4(2)+8

4. B

To find the answer to this problem, we just have to work backwards. We must "divide a number by 5" so we start out with [tex]\frac{n}{5}[/tex]. "n" represents the number that we do not know yet. Then we must "add 4 to the result" so the equation will now look like this: [tex]\frac{n}{5} + 4[/tex]. The problem also states that the answer is 9. Now, the final equation looks like this: [tex]\frac{n}{5} + 4=9[/tex].

If you need to, guess and check is a good way to complete multiple choice questions (until you're able to get help). I recommend asking your teacher for a more in depth explanation if you still don't understand.

Answers

Answer:

I think number 1=209

number 2=120

number 3=89

Step-by-step explanation:

x= 1st aircraft

y=2nd aircraft

z=3rd aircraft

x=y+89

y=z+31

z=y-31

x+y+z=418

y+89+z+31+y-31=418

2y+89+z=418

2y+z=329

2y+(add z)

2y+y-31=329

3y=360

y=120

x=120+89=209

z=120-31=89

what is the least common denominator of 8 and 12

Answers

Answer:

The least common denominator of 8and 12 is 24

The least common denominator of the numbers 8 and 12 is 4.

The given numbers are 8 and 12.

When two or more fractions have the same denominators, they are termed as the common denominators. The least common denominator (LCD) refers to the smallest number that is a common denominator for a given set of fractions.

Here, the factors of the given numbers are

8 = 2×2×2

12 = 2×2×3

So, the common factor is 2×2=4

Therefore, the least common denominator of 8 and 12 is 4.
