Answer:

per hour=$11.53

then

10 hour=$11.53×10

=$115.3

and

the week= 7×$115.3

=$807.10

so that the correct answer is $807.10.

5. y = 2x + 6<br> 2x - y=2

Crank

Step-by-step explanation:

$y = 2x + 6$

$2x - y = 2$

To solve this system of equations, let's first add the equations together:

$(y) + (2x - y) = (2x + 6) + (2)$

$2x = 2x + 8$

$2x - 2x = 8$

$0 = 8$

There are no values of $x$ that will make this equation true, so the lines never intersect, and therefore there are no solutions to this system of equations.

Translate the following words into an algebraic expression.

olganol [36]

Answer:

You've learned how to work with variables and how to evaluate algebra expressions, now we are going to translate words into algebraic expressions.

This skill will come in handy when working with word problems or real life situations. Pay close attention to the "key words" that represent mathematical operations.

You are probably very used to translating words into numerical expressions. Think about this...

We are used to seeing the words, plus, sum, difference, minus, product ...

The good news is that these very same words that we use to write numerical expressions are going to be used to write algebra expressions.

The difference between a numerical expression and an algebra expression is that we will be using variables when writing an algebraic expression. Instead of "8 plus 9" (with two given numbers), you would see, "a number plus 9".

We don't know exactly "what number", so we would use a variable to indicate that it can be any number.

Key words for each operation are indicated in bold. This will help you to easily translate the expression.

As, you can see from the red, bold words, the key words for addition are: sum, more than, plus, increase, add, older than.

Please also remember that addition is commutative; therefore, you can reverse the digits and you will end up with the same answer.

Now, let's take a look at the key words for subtraction.

(x + y + 2)(y + 1)<br> Solve

RideAnS [48]

Hello there! We are given the following equation and want to simplify it:

$(x+y+2)(y+1)$

First, let's use the Distributive Property:

$(a+b)(c)=ac+bc$

For this step, we are going to let:

$a=y$

$b=1$

$c=(x+y+2)$

After applying this version of the Distributive Property, we are given the equation:

$(y)(x+y+2)+(1)(x+y+2)$

We're going to use the distributive party again, but a slightly different version that's almost the same as first:

$(a)(b+c+d)=ab+ac+ad$

Using this on both terms of the equation changes the equation to:

$(xy+y^2+2y)+(x+y+2)$

Now, we just remove the parenthesis and combine like terms

$y^2+3y+xy+x+2$

This should be your answer. Let me know if you need any clarifications, thanks!

yawa3891 [41]

Describe the sample space for this problem: 1200 students at a certain school, all with equal probability of being selected on a random draw.

Which outcome (or outcomes) of the sample space compose the event?

Sophie wins the bike. The chances that that will happen are 1/1200, or 0.00083...
