Answer:

50x

Step-by-step explanation:

Lets start!

5(3​x​ + 7) = 20 – 2(​x​ + 1)

So as we should know we have     'PEMDAS'    standing for parenthesis, exponents, multiplication, division,   and    subtraction. You do math (any math) in the order of PEMDAS.

So lets start out with the parenthesis:

(3x +7) is 10x     and   (x +1) is 1x

now lets multiply:

So now we have that the equation is

5 · 10x · 1x

5 · 10x is 50x   and 50 · 1x is 50x

Therefore our answer is 50x.

Hope this helped have a fantastic day! (✿◡‿◡)

Vlad [161]

Answer:

Ben has mixed up the digit for millions and hundred thousands: he wrote 5 in the place for millions and 6 in the place for hundred thousands, but it should be the other way. I think that he should exchange those two digits in the faulty report.

Paul paid $ 25.50 for 3 cups of hot chocolate and cups of tea. The cost of each cup of tea was 2/3 the cost of each cup of hoy c
Allushta [10]

Let the cost of one cup of hot chocolate  be = x

Let the cost of one cup of hot tea be = y

Paul paid $ 25.50 for 3 cups of hot chocolate and 4 cups of tea.

Equation becomes = 3x+4y=25.50   ...(1)

As given, the cost of each cup of tea was 2/3 the cost of each cup of hot chocolate.

y=\frac{2x}{3}   .... (2)

Putting the value of y from (2) in (1)

3x+4(\frac{2x}{3})=25.50

=3x+\frac{8x}{3}=25.50

=\frac{9x+8x}{3}=25.50

=17x=76.5

x=4.5

y=\frac{2x}{3}

=\frac{2*4.5}{3}

y =3

Hence each cup of hot chocolate is $4.50

Each cup of tea is $3.
