22  True  For all real Numbers A and B,  A  -   B   =    -B   +  A

23  True   For all real Numbers  P, Q, and R, P  -  Q  - R  =  P - R  - Q

24) True For all real Numbers  X, Y, Z and (X   +  Y )  +  Z  =  Z   +  (X  +  Y)

25) False  For all real Numbers M and N,  M/M * N = N/N ==> Example: 5/5  *  3  ≠   3/3  *  5

26) Examples:

Counterexamples =====>   5  - 0  = 5;   5/1   =  5  

5   -  3   ≠  3    -   5;   (5 -  3 )  -    2  ≠   5  -  (3   -  2 );    

6/3    ≠   3/6;   (24/6 )/2   ≠   24/ (6/ 2 )



Hope that helps!!!!                                         : )

Dan saved twice as much as Brett. Maria saved $60 more than Brett. If they saved $600 altogether, how much did Maria save?
givi [52]
Setting it up, we have Dan + Bret + Maria all saving 600.00
Dan = 2B
Bret = B
Maria = B+60

2B + B + B + 60 = 600
4B = 540
B = 135

Dan = 2(135) = 270
Brett = 135
Maria = 135 + 60 = 195

Can someone please help me on e and f i dont understand it and pls explain
Lemur [1.5K]
For parts A, B, C, and D you most likely created a line. What question E is asking is for you to create a line that is perpendicular to the line you already created that also passes through the point (1,1). What is important to understand here is that the slope of the perpendicular line is the negative reciprocal of the original line's slope... if the original slope is (-4/3) than the perpendicular slope is (3/4)... then you should just plug that new slope into point-slope form or slope-intercept form to get your equation... y-y1 = m(x-x1) ... y-1= (3/4)(x-1) ... so it would be y=(3/4)x + 1/4 then for part f just convert into standard form which is just manipulating the variables... look up standard form equation on Google and manipulate the variables from there.
