3(6-4x)-27x=10x-31

18-12x-27x=10x-31

18-39x=10x-31

-49x=-49

Therefore, x=1.


s/6-s/2+1=45/2.

s-3s+6=135

-2s=129

Therefore, s=-\frac{129}{2}.


2(b+5)=3(4-b)

2b+10=12-3b

5b=2

b=\frac{2}{5}

dsp73

Answer:

Correct answer is : $220

Step-by-step explanation:

Here, cost price = $66

Let the selling price be $x.

According to the statement given in problem,

Selling price - cost price = 70% of selling price

i.e.  x  - 66 = 70% * x

x - 70x/100 = 66

30x / 100 = 66

x = 6600 / 30 = $220

i.e Selling price = $220

Math help what is the answer will give brainliest.
artcher [175]
The two equations are
x + y = 7
and
4x + 2.5y = 22
the first equation can be solved for x to be
x = 7 - y
next you can substitute x in the second equation
4(7 - y) + 2.5y = 22
Distribute 4 to everything in the parentheses
28 - 4y + 2.5y = 22
combine like terms:
28 - 1.5y = 22
subtract 28 from both sides of the equation
- 1.5y =  - 6
divide both sides by -1.5
y =  4
plug this in to the original equation of x+y=7
x + 4 = 7
subtract 4 from both sides.
x = 3
