Find the sum of the multiples of 9 from 1 to 300

Answer:

Explanation:

An inequality is used to represent unequal expressions or numbers. An inequality with the solution set [tex]n \ge -2[/tex] is: [tex]2n - 6 \ge -10[/tex]

Given that:

[tex]n \ge -2[/tex] --- the solution

To generate an inequality with the above solution, we do the following:

Subtract 3 from both sides of the inequality

[tex]n - 3 \ge -2 - 3[/tex]

[tex]n - 3 \ge -5[/tex]

Several operations can be carried out. The most important thing to note is that, whatever operation is done on the right-hand side of the inequality must be done on the left-hand side.

We can also multiply both sides by 2

[tex]2 \times (n - 3 )\ge -5 \times 2[/tex]

[tex]2n - 6 \ge -10[/tex]

Hence, an inequality with the solution set [tex]n \ge -2[/tex] is:

[tex]2n - 6 \ge -10[/tex]

Answer:B

Step-by-step explanation:

Answer:

B would be the answer

Step-by-step explanation:

If you reflect the triangle ABC onto EDC then you will see that they are congruent and equal.  

this means that <ABC ~ <EDC

The AA postulate states that if two corresponding angles of two or more triangles are congruent then the triangles are similar.   If you translate ABC onto EDC you can see that all of the angles let alone two are all congruent thus proving that ABC = EDC

Pls mark brainliest if I helped.. Thanks:)

Option (B) is the correct answer.

According to the AA postulate, triangles are comparable if two matching angles of two or more triangles are congruent.

Given that,

∠ABC = 45° and ∠ECD = 45°

Angle-Angle or AA similarity postulate,

When triangle ABC reflect onto EDC, then triangle will be congruent and equal.  

Implies that ΔABC ≅ ΔDEC.

Hence, option (B) is the correct answer.

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

its 62

Answer:

Yes 372 is divisible by 6.

Step 1:

Start by setting it up with the divisor 6 on the left side and the dividend 372 on the right side like this:

Step 2:

The divisor (6) goes into the first digit of the dividend (3), 0 time(s). Therefore, put 0 on top:

Step 3:

Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.

Step 4:

Subtract the result in the previous step from the first digit of the dividend (3 - 0 = 3) and write the answer below.

Step 5:

Move down the 2nd digit of the dividend (7) like this:

Step 6:

The divisor (6) goes into the bottom number (37), 6 time(s). Therefore, put 6 on top:

Step 7:

Multiply the divisor by the result in the previous step (6 x 6 = 36) and write that answer at the bottom:

Step 8:

Subtract the result in the previous step from the number written above it. (37 - 36 = 1) and write the answer at the bottom.

Step 9:

Move down the last digit of the dividend (2) like this:

Step 10:

The divisor (6) goes into the bottom number (12), 2 time(s). Therefore put 2 on top:

Step 11:

Multiply the divisor by the result in the previous step (6 x 2 = 12) and write the answer at the bottom:

Step 12:

Subtract the result in the previous step from the number written above it. (12 - 12 = 0) and write the answer at the bottom.

Answer:

y=-0.2x+5. Correct choice: A)

Step-by-step explanation:

Modeling With Equations

Let's call x the number of minutes and y the distance from home. The correct model should meet both conditions:

After 5 minutes, Ye is 4 miles from home. This is the ordered pair (5,4)

After 15 minutes, Ye is 2 miles from home. This is the ordered pair (15,2)

A) y=-0.2x+5. Testing the first point (5,4): y=-0.2*5+5=4. Correct

Testing the second point (15,2): y=-0.2*15+5=2. Correct

This is the correct choice.

B) y=11/7x-27/7. Testing the first point: (5,4) y=11/7*5-27/7=4. Correct

Testing the second point (15,2). y=11/7*15-27/7=138/7. Incorrect

Incorrect choice.

C) This equation is equal to the choice B), thus this one is incorrect.

D) y=5x-0.2. The first point (5,4) yields to:

Answer:

n = -7

Step-by-step explanation:

Solve for n:

-3 n - 5 = 16

Hint: | Isolate terms with n to the left-hand side.

Add 5 to both sides:

(5 - 5) - 3 n = 5 + 16

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

-3 n = 16 + 5

Hint: | Evaluate 16 + 5.

16 + 5 = 21:

-3 n = 21

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 n = 21 by -3:

(-3 n)/(-3) = 21/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

n = 21/(-3)

Hint: | Reduce 21/(-3) to lowest terms. Start by finding the GCD of 21 and -3.

The gcd of 21 and -3 is 3, so 21/(-3) = (3×7)/(3 (-1)) = 3/3×7/(-1) = 7/(-1):

n = 7/(-1)

Hint: | Simplify the sign of 7/(-1).

Multiply numerator and denominator of 7/(-1) by -1:

300 divided by 6

Step-by-step explanation:

Given that;

Number of crates of apple owned by fruit seller  = 3 crates

Number of apples in each crate  = 100 apples

He packed 6 apples in 1 box;

Unknown:

Number of boxes needed to pack all the apples = ?

This problem is pretty straight forward;

  Number boxes needed to pack all apples  = [tex]\frac{Number of crates owned by fruit seller x number of apples per crate}{Number of apples per box}[/tex]

Input the parameters and solve;
