Answers

Answer 1
Answer: muliply 2×2
your answer will be 3=4+b
subtract the 4 from both sides.
b=-1
if im correct..
Answer 2
Answer:

3 = (2)(2)+b

Simplify both sides of the equation

3 = (2)(2)+b

3 = 4+b

3 = b+4

Flip the equation

b+4=3

Subtract 4 from both sides

b+4-4=3-4

b= -1


I hope that's help !

7e−4=31 solve for e.

Answers

solve your equation step-by-step.

7x−4=31

Add 4 to both sides.

7x−4+4=31+4

7x=35

Divide both sides by 7.

7x/7 = 35/7

x=5
7e-4=31 add 4 to both sides = 7e=35 then divide 7 on both sides then you get the answer of e=5

How do you solve substitution to solve the sytem
x+y=2
-2x+y=2

Answers

so you want to make one of the equations equal to one of the placeholders exg y=x+3

so we have
x+y=2 and
-2x+y=2

I chose to make -2x+y=2 equal to y so
-2x+y=2
add 2x to both sides
y=2+2x

subsitute 2+2x for y in x+y=2
x+2+2x=2
add like terms
3x+2=2
subtract 2 from both sides
3x=0
x=0

subsitute x=0 in x+y=2
0+y=2
y=2

x=0
y=2
separate one variable in either equation, so for example:

x=-y+2
-2x+y=2 

 (if you dont know how to do that, tell me)

now that you have the variable separated, you can substitute the top equation in for the x in the second equation like this

-2(-y+2)+y=2

and now use the distributive property to get:

2y-4+y=2

and just combine like numbers.....

3y-4=2

and if you dont know how to solve it from here, comment to tell me but the rest of the problem would go like this:

3y-4=2
   +4 +4

3y=6
 /3  /3

y=2

and then you take this y and plug it back into one of the original two equations waaayy up at the top like this:

x+2=2

and solve...

x+2=2
  -2 -2 

x=0

so your final answer is (0,2)! Hope this helps!

Step-by-step explanation:
the answer would be C :)

Which property justifies this r(s + t) = rs + rt
statement

Answers

r(s+t) = rs + rt represents Distributive Property because r is multiplying s and t
i.e. ( r*s + r*t ) 
    = rs + rt

So correct answer is Distributive Property.

hope this helps  :)
