Step-by-step explanation:

Answer:

No, 16t -3t equals 13t while 3t - 16t equals -13t

Answer:

No,

16t= 16x2=32

3t=3x2=6

32-6=26

3t=3x2=6

16x2=32

6-32=-26

Answer:

36

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

<A+ <B+ <C = 180

2x+6x+2x = 180

10x = 180

Divide by 10

10x/10 = 180/10

x = 18

We want to find <C

<C = 2x

     = 2*18

    = 36

Answer:

12m,

Step-by-step explanation:

Answer:

4.2 ft

Step-by-step explanation:

We can assume that the truck is vertically straight, so this will make up the vertical side of the triangle.

This means that the triangle is a right triangle since a right angle will be formed with the ground and the 3 ft side.

Next, we have the ramp length which is 5.2 ft long. This will be the hypotenuse of the right triangle since the ramp is slanted.

We want to find the length of the horizontal leg of the right triangle, which will give us the horizontal distance the ramp reaches.

We can use the Pythagorean Theorem since this is a right triangle:

Substitute these values into the equation and solve for b.

The horizontal distance the ramp reaches is 4.2 ft, parallel to the ground.

Answer:

2/7

Step-by-step explanation:

Since the denominators are the same, we need to add the numerators and place it over the common denominator

-4+6 = 2

so

-4/7 + 6/7 = 2/7

2/7

Answer:

10.3

Step-by-step explanation:

The question is asking to find the length of the hypotenuse of the triangle. This requires us to use the Pythagorean theorem. The legs measure 9 and 5, so we use these to solve for c.

[tex]9^{2} + 5^{2} =c^{2} \\81 + 25 = c^{2} \\106 = c^{2} \\[/tex]                            

We find the square root of both sides to find the value of c.

10.295 ≈ c

Rounded to the nearest tenth, c ≈ 10.3. The answer is 10.3

Answer:

[tex]f(x)=600(0.09)^x[/tex]

Step-by-step explanation:

Since f(x) decreases by 9% for every one unit increase in x, it means that f(x) is an exponential decay function. An exponential function is given by:

f(x) = [tex]ab^x[/tex]; where a is the value of f(x) at x = 0, b is the multiplier and is less than 0 for a decay.

Therefore since at x = 0, f(x) = 0. Hence a = 600. Also, b = 9% = 0.09.

The function f(x) can hence be represented as:

[tex]f(x)=600(0.09)^x[/tex]

Answer:

This is a ratio table,so therefore there is always a pattern.

Step-by-step explanation:

In order to solve,you have to find the constant in the question,such as 30,40,50,and 60.The constant in this example is 10.When the constant is not even,or the numbers are not even,that's the time you pull out your notebook multiplication chart.Look at the numbers,and see if those numbers are on the chart.If all of them are on the chart,then see if one or both of the multiplicable numbers fall under the category of your variables.If all are under one number,then that number is your answer.

Answer:

$583 :)

Step-by-step explanation:

well we know the sales tax is %6 and to find out how much money it is equal to we have multiple $550 x 0.06. after that we get $33. Add $33 to $550 and you get $583!

77*22=    1694                     2*22=44

Step-by-step explanation:

22w + 44 = 77 is the equation which represents the situation and the price of a bottle of water is $1.5.

Two or more expressions with an Equal sign is called as Equation.

Let w be the price of a bottle of water.

The coach is buying 22 bottles of water and 22 energy bars, which cost a total of $77.

The cost of 22 energy bars is $2 x 22 = $44.

So the total cost of 22 bottles of water and 22 energy bars is:

22w + 44 = 77

We can simplify this equation by first subtracting 44 from both sides:

22w = 33

Then, we can solve for w by dividing both sides by 22:

w = 1.5

Therefore, 22w + 44 = 77 is the equation which represents the situation and the price of a bottle of water is $1.5.
