Answer:

$10.71

Step-by-step explanation:

$\frac{3.75}{y} =\frac{35}{100}$

y × 35 = 3.75 × 100

35y = 375

35y ÷ 35 = 375 ÷ 35

$y=10\frac{5}{7}$

y = 10.7142857143

10.7142857143 round to 10.71

We want c < 55, so we can write

... 30 + 0.18m < 55 . . . . . your inequality

_____

Here is the solution to the inequality

... 0.18m < 25

... m < 25/0.18

• What is the solution to 5x+ 20 = 7(x+2)?

o-na [289]

For this case we must find the solution of the following equation:

$5x + 20 = 7 (x + 2)$

Applying distributive property on the right side of the equation we have:

$5x + 20 = 7x + 14$

Subtracting 7x from both sides of the equation:

$5x-7x + 20 = 14\\-2x + 20 = 14$

Subtracting 20 from both sides of the equation:

$-2x = 14-20$

Different signs are subtracted and the major sign is placed.

$-2x = -6$

Dividing between -2 on both sides of the equation:

$x = \frac {-6} {- 2}\\x = 3$

Thus, the solution of the equation is $x = 3$

Answer:

$x = 3$
