The temperature of a substance is -29.9 F. The temperature decreases by 8.7 and then again by 17.8"

i want to say 8,16 24 or it could be 3,2,1 or 4,5,6

Answer:

-2, 1, 4, (4 + d) , (4+d+d) , (4+d+d)

We have to first get the common difference

[tex]d = a _{2} - a_{1} \\ d = 1 - ( - 2) \\ d = 1 + 2\\ d = 3[/tex]

Therefore sequence is:

-2, 1, 4, (4 + 3) , (4+3+3) , (4+3+3+3)

Answer: -2, 1, 4, 7 , 10 , 13

Answer:

-8 , -3 , 2

Step-by-step explanation:

f(x) = x-8

f(0) = 0 - 8 = -8

f(5) = 5-8 = -3

f(10) = 10 - 8 = 2

Answer: 800 calories

Step-by-step explanation:

Let us set this up as a fraction

Firstly, convert 3/4 into a decimal

[tex]3 \div 4 = 0.75[/tex]

Now we can set up the fraction

Make sure to put the calories on the same side and hours on the same side as well. So it should be: [tex]\frac{200}{0.75}=\frac{x}{3}[/tex]

Then, solve

[tex]\frac{200}{0.75}=\frac{x}{3}[/tex]

The fractions are supposed to be proportional meaning, if the denominator is a certain number when solved, the numerator should be the same, if solve likely. let me show you:

Divide 3 by 0.75

[tex]0.75 \div 3 = 4[/tex]

Now since the number isn't found yet, we will use the opposite operation, which is multiplication, in this case.

Multiply 200 to 4

[tex]200 \times 4 = 800[/tex]

Therefore, she will burn 800 calories in a 3-hour workout.

Answer:

N____M____O

NO= NM + MO

(5x+2)=25 + (3x-5)

5x+2=3x +20

5x– 3x = 20 – 2

2x= 18

x=18/2

x=9

If you want (NO , MO )this is the solution

NO= 5x+2=5(9)+2=45+2=47

MO= 3x-5=3(9)-5=27-5=22

I hope I helped you^_^

Answer:

18

Step-by-step explanation:

9 ÷ [tex]\frac{1}{2}[/tex]

leave 9, change ÷ to × and turn fraction upside down

9 × [tex]\frac{2}{1}[/tex] = 9 × 2 = 18

Answer:

18

Step-by-step explanation:

If you meant, what is the quotient of 9 ÷ 1/2 we get:

[tex]9/\frac{1}{2}=\\\\9*\frac{2}{1}=\\\\\frac{18}{1} =\\\\18[/tex]

Answer:

600000

Step-by-step explanation:

Cuz it is in the 100000 spot

Answer:

600000

Step-by-step explanation:

Based on the place value system, the digits are ordered from the right to left. So the 6th digit is 6 located in the hundreds of thousands column. The value of the 6th digit is obtained by multiplying the digit by the value of it's place value column

i.e 6 * 100,000 = 600, 000

Ans: 600,000

Answer:

No

Step-by-step explanation:

note [tex]\frac{7}{5}[/tex] = 1.4

and  sinA is defined for - 1 ≤ sinA ≤ 1

Thus sinA ≠ [tex]\frac{7}{5}[/tex]

Answer:

3

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

f(x) = 2x + 4

f(6) = 2(6) + 4

=> f(6) = 12 + 4

=> f(6) = 16

Answer:

x=30

Step-by-step explanation:

Let's solve your equation step-by-step.

3x−40=12x+35

Step 1: Subtract 1/2x from both sides.

3x−40−12x=12x+35−12x

52x−40=35

Step 2: Add 40 to both sides.

52x−40+40=35+40

52x=75

Step 3: Multiply both sides by 2/5.

(2/5)*(5/2 x)=(2/5)*(75)

x=30

Answer:

2x^2 + 5x^2 - x - 6

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Halving the side of the square, results in the perimeter being halved.

new perimeter = [tex]\frac{1}{2}[/tex] original perimeter

Answer:

1. Alternate.

2. cointerior.

3. corresponding.

hope this will help u :)

Fig. 1: Alternate angle

Angles in ' Z ' shape are called alternate angle

Fig. 2: Interior angle

Angles facing each other on the inside are called interior angle

Fig. 3: Corresponding angle

Angles in ' F ' shape are called corresponding angle

6x + 9

I hope this helps!

Answer:

= 6x +9

Step-by-step explanation:

1. you need to multiply -3 by x² + 2x - 3

so you got -3x² -6x + 9

2. Then, you need to multiply 3 by (x²+4x)

= 3x² + 12x

3. -3x² - 6x + 9 + 3x² + 12x

4. then you need to solve with the same

= - 3x² + 3x²

= 0

= - 6x + 12x

= 6x

5. lastly you will got the answer.

# = 6x +9

Answer:

Answer:

B. Going up the elevator 14 floors

Step-by-step explanation:

Choice A can't be right because you are going below sea level (negative).

Choice C can't be correct either because the word "losing" let's you know that it's negative.

Choice D isn't right because if you are taking $20 from your checking account, it would be a negative number.

Hope this helps!
