Question below. Please answer it, its math.
AleksAgata [21]

Answer:

- 0.8

Step-by-step explanation:

The first thing we want to do here is simplify the expression -

\frac{3}{5}( 2x + 5 ) - 2x, Distribute the " \frac{3}{5} " to elements within the parenthesis

= \frac{3}{5} * 2x + \frac{3}{5} * 5 - 2x, Focus on simplifying the expression " \frac{3}{5} * 2x + \frac{3}{5} * 5 "

= 2\cdot \frac{3}{5}x+5\cdot \frac{3}{5} - 2x

= \frac{6x}{5}+3 - 2x, Combine fractions

= -\frac{4x}{5} + 3

= -\frac{4}{5}x + 3

So we have our simplified expression "  -\frac{4}{5}x + 3, " with -\frac{4}{5} being the coefficient of x. Our requirements are that this fraction should be expressed as a decimal, so we can simply divide the numerator by the denominator to figure that out,

- 4 / 5 = - 0.8,

Solution = - 0.8

Please show work 7r + 21 = 49r
gulaghasi [49]

Answer:

1/2 = r

Step-by-step explanation:

7r + 21 = 49r

Subtract 7r from each side

7r-7r + 21 = 49r-7r

21 = 42r

Divide each side by 2

21/42 = 42r/42

1/2 = r
