Ok so you got -30+2r=4(4r-4)
You distribute and get -30+2r=16r-16
Then you subtract 16r on both sides to get -30-14r=-16, then you add 30 on both sides and get -14r=14 then divide both sides by -14 to get r by itself, so the answer is r=-1
(x)(2)+(x+20)(4)=3502x+4x+80=3506x+80=3506x+80-350=2706x+270/6=45 rate of bus45+20 = rate of train
Answer:
x =0
Step-by-step explanation:
Solve for x over the real numbers:
sqrt(x) = 0
Square both sides:
Answer: x = 0
a) algebraic expression

b) Solve and find value of x
x=47
Step-by-step explanation:
We need to translate the following verbal phrase into an algebraic equation
The quotient of three more than a number and five is ten
Let the number be x
three more than a number is written as: 3+x
Since quotient is 10 so,
The algebraic expression will be:

Now, <u>solving to find value of x</u>

Multiplying both sides by 5

Now Subtract -3 from both sides

So, value of x=47
