SOLVES. 'x+4 - 3x = 1+x​

Mathematics
1 answer:
saw5 [17]3 years ago
8 0

Answer:

x =1

Step-by-step explanation:

x + 4 - 3x = 1 + x

Combine like terms:

x - 3x

==> -2x

4 - 2x = 1 + x

Subtract x to each side:

-2x - x        x - x

-3x                 0

4 - 3x = 1

Subtract 4 from each side:

4 - 4             1 - 4

0                   -3

-3x = -3

Divide -3 from each side:

\frac{-3x}{-3}  = \frac{-3}{-3}

==> x = 1

Valentin [98]

Answer:

The number of single-shot espressos sold by the cafe was 49.

Step-by-step explanation:

It is provided that Addison's Cafe offers two kinds of espresso: single-shot and double-shot.

Total number of espressos sold by the cafe yesterday afternoon was,

<em>N</em> = 70

The proportion of single-shot espresso sold was, <em>p</em> = 0.70.

Let <em>X</em> = number of single-shot espressos sold.

Compute the number of single-shot espressos sold by the cafe as follows:

E(X)=N\times p

         =70\times 0.70\\=49

Thus, the number of single-shot espressos sold by the cafe was 49.
