I need the answers immediately! Please please help! There are 12 equations! I think you like- solve the equations on each side of the = sign and see if they are equal..? I'm confused- so could someone please answer them all? I have to have them turned in by 10pm at the latest, and I'm running out of time Worksheet name: Equivalent expressions practice

1) 5(m+6)/5 = m + 6
2) X + 10 = 2x+20/2
3) -9(8 + 4w) = 72 - 4w
4) 3w + 2(-7w + 5) = -11w + 10
5) -2(-7 + 8) - 3x = 11x + 16
6) X + 2 = 30+15x/15
7) 15x + 9 - 12x - 3 = 27x + 12
8) 70 - 4 ÷ 2 • 5 + 7 = 172
9) 41 + 4² • 4 - (6 - 2) = 93
10) 7 + (8 - 4 • 2) = 0 + (15 - 1) ÷ 2
11) (10 ÷ 5) • 4 - 3 = 4 - 2 + 9 ÷ 3
12) 1 + 3 • 4 - 3 = (7 - 4) • 3 + 1

I am also low on points, so I will try to reward the person with the answers more after they get the points I am able to give out. (I'm also really sorry for wasting everyone who has to do these problems time, I was having an anxiety attack in class and so I couldn't pay attention well and I had to leave class to sit in the bathroom until the attack was over; which made me not understand anything) :(

step-by-step explanation:

i took the test: )

3030 ur welcome

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
