How to:
a+b-mx=0
a+b=mx
(a+b)/x=m
Its is two since you take out the decimals then divide regularly
Answer:
Henry is short of gravel
Step-by-step explanation:
Here, we are to identify which of the ingredients Henry is short of.
To identify this ingredient, what is needed to be done is to share the 180kg of concrete appropriately to get which of the material does not meet its ratio and thus allowing us know which is insufficient.
The total ratio is 1 + 4 + 7 = 12
For cement, we have ;
1/12 * 180 = 15 kg
For sand, we have
4/12 * 180 = 60kg
For gravel, we have
7/12 * 180 = 105 kg
From the values in the question, we can see that all the values we have are greater what is shared in the ratio except in the case of gravel. So we can confidently say he is short of gravel
Answer:
B. 12
x = 12
Also you can use mathpapa to help you with math.
You must figure out what is 60% of 125
to find the answer all you need to do is multiply 125 by 0.6
