Answer:

m∠Q = 121°

m∠R = 58°

m∠S = 123°

m∠T = 58°

Step-by-step explanation:

The sum of the interior angles of a quadrilateral = 360°

Create an expression for the sum of all the angles and equate it to 360, then solve for x:

      ∠Q + ∠T + ∠S + ∠R = 360

⇒ 2x + 5 + x + 2x + 7 + x = 360

⇒ 6x + 12 = 360

⇒ 6x = 360 - 12 = 348

⇒ x = 348 ÷ 6 = 58

So now we know that x = 58, we can calculate all the angles:

m∠Q = 2x + 5 = (2 x 58) + 5 = 121°

m∠R = x = 58°

m∠S = 2x + 7 = (2 x 58) + 7 = 123°

m∠T = x = 58°

Answer: $112

Step-by-step explanation:

o get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 560 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 560 is 100%, so we can write it down as 560=100%.

4. We know, that x is 20% of the output value, so we can write it down as x=20%.

5. Now we have two simple equations:

1) 560=100%

2) x=20%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

560/x=100%/20%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 20% of 560

560/x=100/20

(560/x)*x=(100/20)*x       - we multiply both sides of the equation by x

560=5*x       - we divide both sides of the equation by (5) to get x

560/5=x

112=x

x=112

now we have:

20% of 560=112

Answer:

806 ketchup packets

Step-by-step explanation:

5000-1779=3221

3221-2415=806

The restaurant has 806 ketchip packets left

Answer:

5,806

Step-by-step explanation:

Because they got there 5,000 packets they subtracted 1,779 packets

5,000-1,779=3,221

Next remember they get 5,000 packets each week so then you add 5,000 to 3,221

3,221+5,000=8,221

next 2,415 packets were used so subtract 8,221 bu 2,415

8,221-2,415=5,806  so there's your answer

Step-by-step explanation:

Hi there!

We are given the following system:
x-2y=8

8x+6y=42

And we want to solve it by substitution

Substitution is where we solve one of the equations in the system for a variable for an expression containing the other variable, then substitute that expression into the other equation, then solve the equation for that variable, then use the value of the solved variable to find the value of the first variable.

It's easier to solve a system for a variable if the leading coefficient in front of a variable is 1, like with x in x-2y=8

So let's solve the equation for x.

add 2y to both sides

x-2y=8
 +2y +2y
________________
x=2y+8
Now substitute 2y+8 as x in 8x+6y=42

8(2y+8)+6y=42

Multiply

16y+64+6y=42

Subtract 64 from both sides

16y+6y=-22
Add 16y and 6y together

22y=-22

Divide both sides by 22

y=-1

Substitute -1 as y into x=2y+8 to solve for x

x=2(-1)+8

Multiply

x=-2+8

x=6

The answer is x=6, y=-1, or as a point, (6, -1)
Hope this helps!

Answer:

  right triangle

Step-by-step explanation:

I find it convenient to answer questions like this by computing a "form factor" that subtracts the square of the long side from the sum of the squares of the shorter sides. The sign of this value is the sign of the cosine of the largest angle in the triangle.

  f = a² +b² -c²

  f = 11.2² +21² -23.8²

  f = 125.44 +441 -566.44 = 0

The cosine of the largest angle is 0, so that angle is 90° and the triangle is a right triangle.

Answer:

Here we have a problem with translations, where we define a translation as an operation that moves the graph of a function in a given direction.

We will see that the correct option is A.

"The graph of f is shifted 3 units up to create the graph of g."

To get this, we first need to describe vertical translations.

For a function f(x) we define a vertical translation (or vertical shift) of N units as:

g(x) = f(x) + N

If N is positive, the translation is upwards

if N is negative, the translation is downwards.

So here we have:

g(x) = f(x) + 3

So we can see that this is a translation of 3 units upwards, then the correct option is A, the graph of f(x) is shifted (or translated) 3 units up to greater the graph of g(x).

And the graphs of g(x) = x + 3 and f(x) = x can be seen below, where you can see this, where the grey line is g(x).

We are asked to find, how much Carlos owns and how much they have together.

Explanation :-

At first, we just need to multiply 45 by 5, and then we will divide the value by 9, so we find that:

[tex]\qquad[/tex][tex] \bf \longrightarrow 45 \times 5 = 225[/tex]

[tex]\qquad[/tex][tex] \bf \longrightarrow \dfrac{225}{9} = 25[/tex]

Now to find out how much they have together. We have to add Paul's amount to Carlos' amount for that.

Answer:

2.1

Step-by-step explanation:

Here we will simplify the ratio 30:15 for you and show you how we did it.

To simplify the ratio 30:15, we find the greatest common divisor of 30 and 15, and then we divide 30 and 15 by the greatest common divisor.

The greatest common divisor that you can use to simplify 30:15 is 15. Which means the answer to ratio 30:15 simplified is: 2.1
