During a science experiment, your teacher does a demonstration. She takes a
small piece of rope, weighs it to find its starting weight, burns it, and then
weighs it again. The final mass of the product is different from the starting
weight of the reactant.
Why is the final mass different? Does this mean that the product has less
mass? Why or why not?

Answer: 5x - 1 = -6

Step-by-Step Explanation:

We have this diagram here showing numbers and symbols. Just a remainder, "X" is a variable which can be found through and equation of Algebra. Alright, so we have 5 boxes with the symbol "X". Alright, that's a start, so we have 5x as a start of the equation. We have -1 on the same side as well.

Alright, so on the other side- we have Six symbols of "-1".

That concludes to... -6. Alright, notice how all of the symbols are on a Scale, so we can heavily imply that the "=" symbol will take place between the two sets of symbols. Alright, combining them we get.. 5x - 1 = -6.

Answer:

10 cars

Step-by-step explanation:

he can vacuum 3 cars in 17 minutes

so in 1 hour its (60/17) x 3

Or you can do 17/3 for how long it takes to clean 1 car

then divide 60 by that number, you round down for both since you don't complete the car if its a decimal

Answer:

f = [tex]\frac{1}{9}[/tex] [C - 4(h - p)] grams

Step-by-step explanation:

Given that:

   C = 4h + 9f + 4p

where: C is the calorie count contained in the serving, h is the number of grams of carbohydrate contained in the​ serving, f is the number of grams of fat contained in the​ serving, and p is the number of grams of protein contained in the serving.

To solve for the number of grams of fat, then;

C - 4h - 4p = 9f

C - 4(h - p) = 9f

Divide through by 9, so that:

[tex]\frac{C - 4(h - p)}{9}[/tex] = [tex]\frac{9f}{9}[/tex]

[tex]\frac{C - 4(h - p)}{9}[/tex] = f

∴     f = [tex]\frac{1}{9}[/tex] [C - 4(h - p)]

The number of grams of fat, f, contained in a serving of food is [tex]\frac{1}{9}[/tex] [C - 4(h - p)]

Answer:

t=(a+by)/(y-1)

Step-by-step explanation:

(t-b)y =t+a

ty-by = t+a

ty-by=t+a

ty-by=a+by

t(y-1)=a+by

thus,

t=(a+by)/(y-1)

Answer:

7. Yes as far as I know it always is

8. It is possible but not always

9. 159.9 ft

Step-by-step explanation:

Answer:

10°

Step-by-step explanation:

It's a right angle so

90° - 52° = 38°

38 - 8 = 30

30 ÷ 3 = 10

check the work

3 × 10 = 30

30 + 8 = 38

38 + 52 = 90

Answer:

57 is the least out of the 4 numbers or integers here

Step-by-step explanation:

57,58,59,60

hope this helps ;)

[tex]x + 85 + x + 64 + 45 = 180°[/tex]

[tex](x + x) + (85 + 64 + 45)= 180[/tex]

[tex]2x + 194= 180[/tex]

[tex]2x = 180 - 194[/tex]

[tex]2x = - 14[/tex]

[tex]x = \frac{ - 14}{ \: \: \: \: 2} [/tex]

[tex]x = - 7[/tex]

Answer:

x-6 + 2x-8 = 10

Step-by-step explanation:

ST + TU = SU

x-6 + 2x-8 = 10

Combine like terms

3x - 14 = 10

Add 14 to each side

3x-14+14 = 10+14

3x = 24

Answer:

x=2.5

Step-by-step explanation:

2x+3x-4=x+6

5x-4=x+6

4x=10

x=10/4

x=5/2

x=2.5

Answer:

4x=10 or x= 10/4 or x= 5/2 or x= 2 and 1/2 or also E

Step-by-step explanation:

You can combine like terms by adding 2x and 3x, as they have the same variable with no extra additions onto them. You get 5x.

The current equation should look like 5x-4=x+6

Then you can subtract 1x from both sides, to get rid of the x on the right side to get 4x-4=6

Then you can do a similar operation to add 4 on both sides to get 4x=10.

Finally you can divide both sides by 4 (simplifying to get unit rates of x)

You get x = 10/4

You simplify to get 5/2 and it can simplify to a mixed number if needed which is 2 and 1/2

Answer:

1)A.{2,3,5,7,11,13}

2) A.{t| t>4}

Step-by-step explanation:

Choose the correct solution in roster form.

1. S is the set of prime numbers that are less than 15

The Definition of a prime number is given as follows:

A prime number can be defined as the number number that can only be divisible of divided by 1 and itself

Hence the list of prime number below 15 is given as:

2, 3, 5, 7, 11 and 13

Hence, option A.{2,3,5,7,11,13} is correct

2. Write the solution to the inequality in set-builder notation.

9t-4>32

Solving for the given inequality

9t > 32 + 4

9t > 36

t >36/9

t > 4

Therefore, the solution to the inequality in set-builder notation is:

Option A.{t| t>4}
