Create a proportion using the form %/100 = is/of to represent the following word problem. 15 is 1 1/2% of what number?
Tema [17]
Let the required number be x, then to create a proportion using the form
\frac{\%}{100} = \frac{is}{of}

Thus, let 15 be 1 \frac{1}{2} \% of x, then
\frac{1 \frac{1}{2}}{100} = \frac{15}{x}  \\  \\  \frac{ \frac{3}{2} }{100} =\frac{15}{x} \\  \\ \frac{3}{2}x=1,500 \\  \\ x= \frac{1,500\times2}{3} =1,000

Therefore, 15 is <span>1 \frac{1}{2} \% of</span> 1,000

I don’t know how to do this, please explain :(
IrinaK [193]

Answer:

1. Adjacent and formed a linear pair

2. Adjacent and formed a linear pair

3. Adjacent

4. Not adjacent

Step-by-step explanation:

In essence, adjacent angles are two angles side by side. Two adjacent angles can form a linear pair when they are created by two lines intersecting. So, in broad terms, they are adjacent on a flat plane (or a straight line), and together they make a 180° angle.

7 times the difference between m and 8​
aniked [119]

Answer:

7(m-8)

Step-by-step explanation:

We are given: 7 times the difference between m and 8

We want to write an expression. Let’s begin with “the difference between m and 8”.

Difference means subtraction. Therefore, we must subtract m and 8.

(m-8)

Now, let’s add on “7 times”

Times means multiply. Therefore, we must multiply 7 and the expression we just wrote.

7(m-8)

Therefore, 7 times the difference between m and 8 can be written as: 7(m-8)
