Let’s start with Y
Y= -2x+4. Which is positive 2x
Now 3(2x)=x-2
We still don’t know the numeral of X
3(2x)=6x
6x= x-2
Therefore your answer would be 6x=x-2
Answer:
2 gallons
Step-by-step explanation:
25% of 4 gallons is 1 gallons, which means that 75% of the hand sanitizer is not alcohol, and is 3 gallons. since that is the amount of not alcohol, and we want it to be 50% solution, it has to be 3 gallons of alcohol in total, and 3-1=2.
You need subtract 3z from both sides equal
2 = 5
This answer is have many solution so the answer is
2=5
Many solution
Answer:
The correct statements are A & C.
Step-by-step explanation:
<u>Standard deviation:</u>
Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value.
- A low standard deviation means that most of the numbers are close to the average.
- A high standard deviation means that the numbers are more spread out
Statement A is correct, City A's heights are more spread than City B's, because. City A's standard deviation is greater than City B.
Statement C is correct, because city A's mean is lesser than City B.
Answer:
18.75
Step-by-step explanation:
Remark
For this question, you need to set up a proportion. The ratio on each side of the equal sign is dollars over pounds.
Proportion
15/8 = x / 10 Cross Multiply
Solution
8x = 15 * 10 Combine
8x = 150 Divide by 8
x = 150/8
x = 18.75
