During Raul’s exercise program, he recorded how much weight he lost or gained each week. After 5 weeks, Raul had collected the d

ata shown in the chart. He
thought, “I can use the Inverse Property and the Identity Property to help me find out how much my weight has changed.”


Week l Weight lost or gained (In pounds)
---------l-------------------------------------------
1 l -3
2 l -2 1/2
3 l +1
4 l -1 1/2
5 l+1

A. The total of Raul’s numbers is not 0.
B. Raul’s list of numbers does not include 0.
C. Raul’s list of numbers includes opposites.

Solve the systems by the addition method x - 2y = - 4 2x + y = 7
vfiekz [6]
<h2>x - 2y = -4</h2><h2>2x + y = 7</h2><h2 />

To solve this system of equations by addition, our first goal is to cancel

out one of the variables by adding the two equations together.

However, if we add these two equations together right away, nothing

will cancel so we need to set things up so a variable will cancel.

Notice that we have an 2x in our second equation.

If we had a -2x in our first equation, then the x's would cancel out.

In order to create a -2x in the first equation, we simply

multiply both sides of the first equation by -2.

So we have (-2)(x - 2y) = (-4)(-2) which can be rewritten as -2x + 4y = 8.

Now rewrite both equations, as shown below.

<h2>-2x + 4y = 8</h2><h2>2x + y = 7</h2><h2 />

Now when we add the equations together, the x terms

will cancel out and we're left with 5y = 15.

Dividing both sides by 5, <em>y = 3</em>.

To solve for x, plug a 3 in for y in either one of our 2 original equations.

So let's go with our second equation.

Plugging a 3 in for y, we get 2x + (3) = 7.

Now subtract 4 from both sides to get 2x = 4.

Dividing both sides by 2, we fid that <em>x = 2</em>.

Since x = 2 and y = 3, our answer is the ordered pair (2, 3).

Answer:

21 boxes of books

Step-by-step explanation:

guy= 140 lbs

each box= 40lbs                       elevator can only weigh up to 1010

i took 1010- 140 and got 870lbs left for the books

then i took 870 divided by 40 (to see how many boxes of books can be put on the elevator) and got 21.75

so 21 boxes could go on the elevator at a time

In a pre algebra class containing 40 students, there are 18 freshmen, 19 sophomores, and 3 juniors. What fraction of the class a
dezoksy [38]

\frac{9}{20} of the class consists of freshmen.

Step-by-step explanation:

Given,

Total number of students = 40

Number of freshmen = 18

Number of sophomores = 19

Number of juniors = 3

Fraction of freshmen = \frac{Number\ of\ freshmen}{Total\ number\ of students}

Fraction of freshmen = \frac{18}{40}

Fraction of freshmen = \frac{9}{20}

\frac{9}{20} of the class consists of freshmen.
