Answer 1

Answer:

Answer:

see below

Step-by-step explanation:

The two marked points are equidistant from their average, which is ...

(-3 +9)/2 = 6/2 = 3

The distance they are from that average is 9-3 = 3 -(-3) = 6.

So, you want an expression that is equivalent to ...

|x -3| = 6

Subtracting 1 from both sides of this equation gives you the one seen in choice B:

|x -3| -1 = 5

area = length x width

x² + 12x = l * x

A.

First, you factor x from x² + 12x

$x^(2) +12x=x(x+12)$

area = x (x+12)

area = (x+12) * x

Length = x + 12

B.

If x = 10,
l = x + 12 = 10 +12 = 22
length = 22
and
Area = x² + 12x = 10² + 12(10) = 100 + 120 = 220
area = 220

Hope this helps :)

If you get 12 how many do you have to get wrong to get an 58%

Answers

Answer:

I'm gonna take some liberty. I assume you mean if there is 12 questions. if so that means you would need to get 5 wrong.

Step-by-step explanation:

Here are step-by-step instructions showing you how we calculated 7 out of 12 as a percentage: The first step is to divide 7 by 12 to get the answer in decimal form: 7 / 12 = 0.5833. Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.5833 * 100 = 58.33%

Emma has 16 crackers she eats some could she still have 16 left?

Answers

The inequality equation is A < 16 , where A is the number of crackers

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the number of crackers be represented as A

Now , the inequality equation will be

The initial number of crackers = 16 crackers

Emma eats some of the crackers

So , the remaining number of crackers is less than 16

And , the relation will be

The number of crackers A is always less than 16

Substituting the values in the equation , we get

A < 16

Hence , the inequality relation is A < 16
