the sum of a number and -43 is 102.what is the number ​

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.

Answer:

600m

Step-by-step explanation:

-200 + 200 = 0, 0 to 400 need 400, 400 + 200 = 600 i guess lol

Answer:

The answer is not greater because it is a negative. If you mean less than it is exactly 400 less than 400 m.

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

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.

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

Answer:

(4,3)

Step-by-step explanation:

To get from the fire pit to the tree, you have to go up 6 and over 6. 1/3 of each of those distances is 2 (6*1/3). So to get 1/3 of the distance, you have to go up to and over 2 from the fire pit. That would land at the point (4,3)

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]

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).

5x+8=x

Step 1: Subtract x from both sides.

5x+8−x=x−x

4x+8=0

Step 2: Subtract 8 from both sides.

4x+8−8=0−8

4x=−8

Step 3: Divide both sides by 4.
