I would say read it well and then write down an equation or expression to represent the data so its easier for you to understand and/or solve.
Answer:
X = 4
Step-by-step explanation:
x2 + 1 = 9
We have to cross 1 over to the other side so that x becomes a value on its own. Because we are it over, the addition sign changes to subtraction which makes the expression,
x2 = 9- 1
x2 = 8
For x to stand alone we have to divide both sides by 2
x 2/2 = x
and 8/2 = 4
Therefore x=4 (Answer)
Answer:
2.5x-y=0
Step-by-step explanation:
You will have to understand this question before solving
According to the question 2.5 teaspoon of sugar is required for making one candy
Then y teaspoon of sugar is required to make y candy
Let's start
2.5 sugar=1 candy
y sugar=x candy
Let's cross multiply
y=2.5×x
y=2.5x
Which can also be written as
2.5x-y=0
Therefore the final answer is 2.5x-y=0
Answer: 69.3
Explanation: So if the height is 13.1, that means that the length is 2.3. And to find volume, you do length times width times height. So the width would be 2.3 because it is a even square if that makes since. Now 2.3 times 2.3 is 5.29. Now we multiply 5.29 by 13.1. The answer is 69.299. Now we round this to the nearest tenth, so the answer would be 69.3.
