14% of 120

Answers

you do 120 x .14 which gives you 16.8%. this is because you convert 14% to 0.14 so 1.00 is 100 percent. ex 28% is .28 and. 5% is .05 (remeber to put in hundredths place) and then just multiple that percent diver by the original number.

(–4, 3)
(–3, –4)
(–3, 4)

Answers

I took a photo of my work and if you don’t understand how I got something just tell me

Answer - (-3, -4)

The solution to the linear equations will be ( -3, -4 ).

What is linear equation?

The equation whose highest degree of the variable used in the equation is 1 is called linear equation.

For example 12x+5y=19 is a linear equation.

We have,

- 4x + y = 8     .....(i)

x - 5y = 17     .....(ii)

Now,

Rewrite equation (ii) ,

x - 5y = 17  

⇒ x = 5y + 17     .....(iii)

Now substitue  this value of x in equation (i) i.e. - 4x + y = 8

We get,

- 4(5y + 17) + y = 8

- 20y - 68 + y = 8

- 19y - 68 = 8

- 19y = 8 + 68

-19y = 76

⇒ y = - 4

So, we have a value of y now substitute this equation (iii),

We get,

x = 5(-4) + 17

x = - 20 + 17

x = - 3

So,

The solution to the given linear equations is ( -3, -4 ).

A. 20/25
B. 41/51
C. 20/10
D. 8/25
E. 50/40
F 39/49

Answers

Answer:

A

Step-by-step explanation:

You can divide 40 by 2.....this gives you 20.

Whatever you do to the top, do to the bottom.

Divide 50 by 2.....this gives you 25.

Your answer is 20/25

Answer:

A

Step-by-step explanation:

You can actually use simple division to help you solve this problem. The ratio given is 40/50. Well, divide the two numbers of the ratio. You will then get, 4/5 (.8 as a decimal). You can then do the same to all of the answer choices and see which one gets you the same decimal or fraction.

1)The average height of 4 boys is 1.65m. One boy is 1.68m tall. Find the average height of the other 3 boys.
2) Ian, John and Juan shared a sum of money in the ratio 4:7:9. What percentage of the sum of money did John receive?
3) The usual price of a refrigerator is $800. It is sold at a discount of 15%.find the selling price.

Answers

1)
If the average height of the 4 boys is 1.65m that means the total of their heights is 6.6m

To get the average height of the other 3 boys you have to take away the one boys height from the total and divide that number by 3

6.6-1.68 = 4.92
4.92/3 = 1.64

Therefore the average height of the other three boys is 1.64m

2)
To do this you first find the total of the parts of the ratio so
4+7+9 = 20

Next you find what percentage each part is worth so
100/20 = 5
This means that each part of the ratio is worth 5% of the total sum

Because John received the 7 in the 4:7:9 ratio you times 7 by 5
7x5 = 35

Therefore John got 35% of the total sum of the money

3)
The formula for finding the discounted price using the percentage discount is
Discounted Sale price = (100% - %Discount) x Regular Sale Price

Using this formula to find the discounted sale price you do

(100% - 15%) x 800
= 85% x 800
= 680
Therefore the selling price of the refrigerator is $680

Write a procedure that explains how to use a number line to add integers and counters to subtract integers. Include diagrams and examples.

Answers

We can use the number line as a model to help us visualize adding and subtracting of signed integers. Just think of addition and subtraction as directions on the number line. There are also several rules and properties that define how to perform these basic operations.

To add integers having the same sign, keep the same sign and add the absolute value of each number.

To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.

Subtract an integer by adding its opposite.

Examples:

4+(-8)=?   Add a negative interger by moving to the left. Start at 4 and move 8                                units to the left. 4+(-8)=-4

-4-(-3)=?   To subtract an integer, add its opposite. Add the opposite of -3 , or 3.   -4-(-3)= -4+3=-1

Sam is 8 years younger than his brother Steve. He is also half as old as Steve.

Select two equations of a system that can be solved to find both ages.

Answers

Answer:

Step-by-step explanation:

B and A

Let his sam’s age = y
And his brothers age = x
If y = x*(1/2)
And y = x - 8
x - 8 = x/2
Cross multiply
2(x - 8) = x
2x - 16 = x
Collect like terms
2x - x = 16
x = 16
Hence, if y = x/2
y = 16/2
y = 8
Check:
y = x/2
8=16/2
8 = 16

What are like terms? How do you combine them? Whats an example
I NEED HELP ASAP PLEASE

Answers

Answer:

like terms are terms that have the same variable

Step-by-step explanation:

when combining like terms we add their coefficients for example 4x + 5x = (4+5)x=9x

Examples of like terms are:
5d & 7d
3x & 2x
10 & 4
7 & -6

You combine them by simply doing what the equation tells you:
For example:
4d + 6 - 2d + 10
This would simplify to:
2d + 16

This is because I took the like terms, 4d & -2d, and 6 + 10.

4d - 2d = 2d
6 + 10 = 16

So the answer would be:
2d + 16

Answer:

B. y = 1/2x - 2

Step-by-step explanation:

The slope-intercept form is:

y = mx + b

According to the table, point (0, -2) we see:

y-intercept is - 2

And using two points (4, 0) and (8, 2) we can find the slope:

m = (2 - 0)/(8 - 4) = 2/4 = 1/2

So the line is:

y = 1/2x - 2

Correct option is: B

Given the graph below write the equation of the line.
y = 2 + 2
y = -2x
y = 2x + 8
y = 0x + 8

Answers

Answer:

y = 2x+8

Step-by-Step Explanation:

The equation should be in the form of y=mx+b

So you already know it's not A. Also you already know it's not D because the line goes at an angle, if "m"(slope) was 0 then the line would be straight horizontal or straight vertical. So that leaves B and C. And finally you know it's not B because the line is going in the positive direction not negative, so the slope has to be positive, also "b" in the equation is the y-intercept, and that's where the line intersects with the y-axis, and you can see that the line intersects at 8 on the graph. Therefore, the answer is C, y=2x+8

Hope this helps!! :)

y=2+2, y=-2x, y=2x+8, and y=0x+8
