Answer:
Not exactly sure if you are asking to simplify, but that is all I can do with the information you have given.
Here is the simplified version:
−2.3d + 4.7h − 15
Step-by-step explanation:
Combine Like Terms:
=8h+−6.3d+−15+4d+−3.3h
= (−6.3d+4d) + (8h+−3.3h) + (−15)
= −2.3d+ 4.7h − 15
Answer: x = 34
Explanation:
x/8.5 = 16/4
x/8.5 = 4
x = 4 x 8.5
x = 34
Okay, here we have this:
Considering the provided information, we are going to calculate the requested value, so we obtain the following rule of three:

Solving for x:

Finally we obtain that 87.5mL of water should be used for 250g of plaster.
Answer:
25%
Step-by-step explanation:
X=(18.75*100)/75
I am sorry but it is just an example !
Question ) A university has 30,330 students. In a random sample of 270 students, 18 speak three or more languages. Predict the number of students at the university who speak three or more languages.
Answer ) 2,022 students will speak three or more languages
Here's why:
Using proportions.
18. x
--- =. ----
270. 30,330
Cross multiply
18 x 30,330 = 545,940
270 multiply x = 270x
545,940 divided by 270 = 2,022
x = 2,022 students
