The sum of six times a number and six more than the number is the same as the difference between -30 and twice the number what is the number

Answer:

12.5 hours

Step-by-step explanation:

[tex]115 - 15 = 100 \\ \frac{100}{8} = 12.5[/tex]

The student worked for 12.5 hours.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

A student earns $8 per hour plus a $15 bonus each weekend day worked.

Now, let the student works for h hours.

So, the earning would be= 15+ 8h

As, he earned $115

So, 15+ 8h= 115

8h = 100

h = 12.5 hours

Hence, the student worked for 12.5 hours.

Answer + Explanation:

1. you want to rearrange the equation ( don't change the actual value ) to put it in the form y = mx + b. in this form, m represents the slope and b represents the y-intercept.

this is how you would do that:

4x - 3y = 12

subtract 4x from both sides

-3y = -4x + 12

divide both sides by -3

y = 4/3x - 4

this means the slope is 4/3 and the y-intercept is -4

2. do the same thing, rearranging into y = mx + b form

2y = 6x - 12

divide both sides by 2

y = 3x - 6

this means the slope is 3 and the y-intercept is -6

Answer:

  a) S gets tends to infinity

  b) S tends to zero

Step-by-step explanation:

As you know, dividing by larger numbers makes a quotient smaller. The converse is also true: dividing by smaller numbers makes the quotient larger.

b) The area of the label will get smaller as r gets larger. It will tend toward zero.

Answer:3,312.50

Step-by-step explanation:1. We assume, that the number 2500 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 2500 is 100%, so we can write it down as 2500=100%.

4. We know, that x is 3.25% of the output value, so we can write it down as x=3.25%.

5. Now we have two simple equations:

1) 2500=100%

2) x=3.25%

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:

2500/x=100%/3.25%

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

Answer:

See image

Step-by-step explanation:

An equation is really like a scale with two equal things on both sides. You could use the idea of a scale and lift off the same amount from both sides to keep it balanced. But I will show you the algebra version. When we subtract the same thing from both sides that's how we work back to our answer while keeping the scale balanced.

The total number of students is 50

The number of students that named lacrosse as their favorite sport is given as:

[tex]Lacrosse = 19[/tex]

From the circle graph, 38% chose lacrosse.

So, the proportion of students that represent lacrosse is:

[tex]Lacrosse = 38\% \times Students[/tex]

Substitute 19 for lacrosse

[tex]19= 38\% \times Students[/tex]

Multiply both sides by 100

[tex]1900 = 38 \times Students[/tex]

Divide both sides by 38

[tex]50 = Students[/tex]

Rewrite as:

[tex]Students = 50[/tex]

Hence, the total number of students is 50

Answer: dont even know tbh

Step-by-step explanation:?

The smallest integer from the given set {-17, -7, -12, 2} is -17, making option D the right choice.

An integer is a whole number that can be positive, negative, or zero and is not a fraction.

The integer values are in the following order: negative, zero, then positive.

The real value of a negative integer decrease as the number increases.

For positive integers, the real value increases as the number increases.

In the question, we have been asked for the integer with the smallest value in the set {-17, -7, -12, 2}.

As discussed above, we know the order for negative and positive integers.

Thus, arranging the set in ascending order, we get:

-17 < -12 < -7 < 2.

Thus, the smallest integer from the given set {-17, -7, -12, 2} is -17. Hence, option D is the right choice.
