If you round me to the nearest ten, then I round up not down
Who am I?​

Answer:

the answer is 8 because when you set the equation equal to 12 and solve it you get 12

Step-by-step explanation:

Final answer:

To find the input for f(x) = 2x + 4 when the output is 12, solve the equation 12 = 2x + 4 for x, resulting in the input-value x being 4, with the ordered pair being (4, 12).

Explanation:

The question concerns finding the input for a given function when the output is known. The function provided is f(x) = 2x + 4, and we want to find the input value, or x, that produces an output, or f(x), of 12. To do this, we set up an equation where 12 = 2x + 4 and solve for x.

We first subtract 4 from both sides of the equation to get 8 = 2x. Then, we divide both sides by 2 to isolate x, resulting in x = 4.

The ordered pair representing the input-output relationship for the function when the output is 12 is (4, 12).

Answer:

$283.05

Step-by-step explanation:

first divide $244.80 by 32, to find out how much you are making hourly. in this case you are making $7.65 an hour

next, multiply $7.65 by 5, to add the 5 hours, in this case you get $38.25.

next, add $38.25 to $244.80 and you get your answer!

Final answer:

To find out how much you would receive for 37 hours of work, set up a proportion using the given information and solve for x. The result is approximately $283.98.

Explanation:

To find out how much you would receive for 37 hours of work, we can set up a proportion using the information given. Since 32 hours of work pays $244.80, we can set up the proportion: 32/244.80 = 37/x. Cross-multiplying, we get: 32x = 244.80 * 37. Simplifying, we find that x = (244.80 * 37) / 32. Calculating the result, we find that you would receive approximately $283.98 for 37 hours of work.

Step-by-step explanation:

8 5/8 + 8 7/8

=17 1/2

Answer:

17 1/2

Step-by-step explanation:

8 5/8+8 7/8=...

So, let's take away the fractions for now.

What's 8+8?

Well, 8+8=16.

Now, let's take a look at the fractions.

5/8+7/8=...

Well, when we are adding fractions, the denominator will stay the same. So let's pretend that we are adding 5+7.

5+7= 12. So our answer is 16 12/8 Right?

wrong.

you will simplify the 12/8. Since the numerator is more than eight, we will subtract 8 from 12.

12-8=4

we will make the 8/8 a 1 and add it to the 16 to make it 17 4/8. We can still simplify this. The 4/8 becomes 1/2 making the answer: 17 1/2

Answer:

3x = 6 + x

Step-by-step explanation:

We can express the product of a number and 3 as:

3x

Where x is the number that we don't know.

Now it says that that product is 6 more than the number (x) so we can write it down:

3x (The product of a number and 3) = (is) 6 + x (6 more than the number)

3x = 6 + x

The sentence 'the product of a number and 3 is 6 more than the number' can be translated into the algebraic equation 3x = x + 6.

The given statement can be translated into a mathematical equation in the following way: If we let x be the number in question, the first part of the sentence tells us that the product of the number and 3 can be modeled as 3x. The second part of the sentence tells us that this is 6 more than the number itself. This can be translated into the equation as x + 6. Thus, putting the two parts together, we get the algebraic equation 3x = x + 6.

Answer:

Second picture: y=4 and x=7

First picture: x=70 degrees y=20 degrees

Step-by-step explanation:

Second picture:

One of the given triangles is an equilateral and the other is an isosceles.

Equilateral triangle has all congruent sides and it's angles are all congruent.

Isosceles triangle has two congruent angles and the opposite sides of those congruent angles are also congruent.

This implies all the side algebraic expression-measurements given are all equal.

5y-4=y+12

Add 4 on both sides:

5y=y+16

Subtract y on both sides:

4y=16

Divide both sides by 4:

y=4

So what is the side measurement for each of the sides given in terms of algebraic expressions?

y+12

4+12

16

Each side given in terms of an algebraic explanation is 16 units.

So we have also the following equation to solve:

3x-5=16

Add 5 on both sides:

3x=21

Divide both sides by 3:

x=7

So x=7 and y=4.

There is only one side in the picture that is possibly not 16. It is the one of the sides in the isosceles, not opposite the base angles.

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

First picture:

We are given x+y=90.

Since that one triangle is an isosceles we know that x+x+(180-40)=180

So let's solve the second equation for x then go back and solve for y in the first equation.

2x+140=180

Subtract 140 on both sides:

2x=40

Divide both sides by 2:

x=20

First equation:

x+y=90

So y=90-x=90-20=70.

Answer:

The cost of a shirt is $16 and the cost of a sweater is $33

Step-by-step explanation:

Let

x -----> the cost of a shirt

y -----> the cost of a sweater

we know that

[tex]3x+2y=114[/tex] -----> equation A

[tex]2x+4y=164[/tex]----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both graphs

The solution is the point (16,33)

see the attached figure

therefore

The cost of a shirt is $16 and the cost of a sweater is $33

Answer:

The cost of each shirt is 16$ and the cost of each sweater is 33$

Solution:

Let us consider “x” as the cost of each shirt and “y” as the cost of each sweater.

From question, Andrea has bought 3 shirts and 2 sweaters for 114$. Hence we form equation as,

3x + 2y = 114 ------  eqn 1

Similarly, Andrea has bought 2 shirts and 4 sweaters for $164. Hence we form equation as,

2x + 4y = 164 ----- eqn 2

By solving equation 1 and equation 2, we get the value of “x” and “y”.

On multiplying equation 1 by 2,we get  

6x + 4y = 228 -------- eqn 3

Now solving eqn 2 and eqn 3

6x + 4y = 228                      

-2x - 4y = -164      

4x + 0y = 64

4x = 64

[tex]x =  \frac{64}{4}[/tex]

x = 16

Substituting the value of x in eqn 1, we get

3(16) + 2y = 114

48 + 2y = 114

2y = 114 - 48

2y = 66

[tex]y = \frac{66}{2}[/tex]

y = 33

Thus the values of x and y are 16 and 33. So the cost of each shirt is 16$ and the cost of each sweater is 33$

The coordinates of the point is (-5,3)

Let the initial coordinate be:

Initial = (0,0)

5 units to the left of the x-axis represents a horizontal translation left by 5 units.

So, we have:

New = (0 - 5,0)

3 units above the y-axis represents a vertical translation up by 3 units.

So, we have:

New = (0 - 5, 0 + 3)

Evaluate

New = (-5, 3)

Hence, the coordinates is (-5,3)

Answer:

x = 121

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 7, thus

sum = 180° × 5 = 900°

Sum the given angles and equate to 900

x + 125 + 119 + 117 + 145 + 133 + 140 = 900, that is

x + 779 = 900 ( subtract 779 from both sides )

x = 121

Answer: 320

Step-by-step explanation:

there are 16 tablespoons in one cup so 20*16=320

To calculate the calories in one cup of chocolate chips, you multiply the number of calories per tablespoon (20) by the number of tablespoons in a cup (16), resulting in 320 calories per cup.

To determine how many calories are in 1 cup of chocolate chips, knowing that there are 20 calories in 1 tablespoon, we first need to understand the conversion between tablespoons and cups. There are 16 tablespoons in a cup.

Therefore, to find out how many calories are in a full cup, you would simply multiply the number of calories in one tablespoon by the number of tablespoons in a cup:

20 calories / tablespoon × 16 tablespoons / cup = 320 calories / cup.

Thus, there are 320 calories in 1 cup of chocolate chips.

Answer:

512 in³

Step-by-step explanation:

Given the volume (V) of a cube is calculated using

V = s³ ← s is the side length

When s = 8, then

V = 8³ = 8 × 8 × 8 = 64 × 8 = 512 in³

Answer: 512 in.³

Step-by-step explanation: To find the volume of a cube, first start with writing down the formula for the volume of a cube which is as followed.

Volume = Length × Width × Height

In this problem, our prism is a cube. Since the length, width, and height of a cube are all equal, we can find the volume of a cube by simply multiply side times side times side or s³.

Volume = Length x Width x Height

Volume = (8) (8) (8)

Volume = 512 in³.

Therefore, the volume of the cube is 512 in.³.

Answer: Hello mate!

our equation is y - 5 = 6(x + 1), and we want to rewrite it in the slope-intercept form.

First lets distribute the parenthesis.

y - 5 = 6(x+1) = 6x + 6

y-5 + 5 = 6x + 6 + 5

y = 6x + 11
