Ken predicts that the average temperature will be -5°C in December. If he predicts the temperature will rise 6°C in
January and fall 3°C in February, which of the following equations can he use to find the sum of the temperatures for
those months? Check all that apply.
[6 + 3] + 5 = 14
0 (-5) + [3 + 6) = -4
[(-5)+(-3)] + 6 = -2
5+[(-6) + (-3)] = -4
[6 + (-5)] +(-3) = -2
D[(-5) +6] +(-3) = 4

Answer:

-39

Step-by-step explanation:

This sequence follows the pattern of subtracting 7 each time. We can prove this:

31 - 7 = 24, 24 - 7 = 17, 17 - 7 = 10

So if we were to continue to the 11th term, we would subtract 7 more times.

1. 10 - 7 = 3

2. 3 - 7 = -4

3. -4 - 7 = -11

4. -11 - 7 = -18

5. -18 - 7 = -25

6. -25 - 7 = -32

7. -32 - 7 = -39

The 11th term in the sequence would be -39.

Answer:

root3/ root2

Step-by-step explanation:

since this is a special right triangle (45, 45, 90) we can use right triangle rules. Basically, C in my photo is equal to the hypotenuse while A and B are equal to the sides. You can substitute your hypotenuse into the formula I gave you to find x.

B = C / root2

x = root3 / root2

Step-by-step explanation:

The answer of EG is 30. We can find it by Triangle Proportionality Theorem and Angle Bisector Theorem.

According to Triangle Proportionality Theorem, A triangle's other two sides are proportionately divided by a line that runs parallel to one of its sides.

So here, [tex]\frac{DN}{NG} = \frac{DM}{ME}[/tex] (Triangle Proportionality Theorem)

⇒ [tex]\frac{30}{24} = \frac{y}{12}[/tex]

⇒ 24 * y = 30 * 12

⇒ y = 15

So, we get [tex]DE = y + 12 = 15 + 12 = 27[/tex]

The angle bisector theorem states that a triangle's opposing side is divided into two halves by an angle bisector that is proportionate to the triangle's other two sides. 

Now, we can find EG by Angle Bisector Theorem,

⇒ [tex]\frac{DG}{FG} = \frac{DE}{FE}[/tex]

⇒ [tex]\frac{54}{x+10} = \frac{27}{x}[/tex]

⇒ [tex]54x= 27 x + 270[/tex]

⇒ [tex]54x-27x = 270[/tex]

⇒ [tex]27x = 270[/tex]

⇒ [tex]x = 10.[/tex]

So, [tex]EG = x + x + 10 = 2x + 10 = 20 + 10 = 30[/tex].

So, finally we get EG = 30.

Answer:

23/5

is the 4.6 fraction

The decimal 4.6 is equivalent to the fraction 23/5.

The whole number part of the decimal, which is 4, will be the numerator of the fraction.

The decimal part, which is 0.6, will be the numerator of the fraction divided by the appropriate power of 10.

In this case, the decimal has one digit after the decimal point, so we divide it by 10¹.

0.6 / (10¹)

= 0.6 / 10 = 6/10

Simplify the fraction if possible.

Both the numerator and denominator can be divided by their greatest common divisor, which is 2 in this case.

6/10 = (6/2) / (10/2) = 3/5

Therefore, the decimal 4.6 is equivalent to the fraction 4 3/5 or simply 23/5 after simplification.

Answer:

She shouldn't tip at all since that's a ridiculous concept

Step-by-step explanation:

common sense

SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP

The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so

cost = price + 0.1*price

cost = 1.1 * price

price = cost / 1.1

price = 22 / 1.1 = 20

now we need 20% of that so that's

20 * 0.2 = 4

If she's simple-minded enough to tip that would amount to $4

Answer:

x=2

Step-by-step explanation:

You have to subtract 8 from both sides.

-5x+8=-2

-8 -8

----------------

-5x= -10

now divide both sides by -5.

x=-10/-5

(And two negatives make a positive.)

x=10/5

now you have to simplify 10/5

10/5 simplified is 2

so the answer is:

x=2

Answer:

Negative

Step-by-step explanation:

Think about it this way, you cannot do something positive and then do something negative and it still be positive. You cannot do something negative and then do something positive for it to be positive. But you can do something positive and do something else positive for it to remain positive the same with negative. Therefore the answer is "negative."

Rules:

Positive ÷ Negative = Negative

Positive × Positive = Positive

Negative ÷ Negative = Positive
