Answer:

x =2

Option D is correct !!!

Step-by-step explanation:

By Pythagoras theorem we can solve this

we know that:

${x}^{2} + {4}^{2} = \sqrt{20} {}^{2}$

${x}^{2} = \sqrt{20} ^{2} - 16$

${x}^{2} = 20 - 16$

$x = 2$

-12x - 0.4 > 0.2(36.5x + 80) - 55 Remove the brackets.

-12x - 0.4 > 7.3x + 16 - 55 Combine the like terms on the right

-12x - 0.4 > 7.3x - 39 Add 12x to both sides

- 0.4 > 7.3x + 12x - 39

- 0.4 > 19.3x - 39 Add 39 to both sides.

-0.4 + 39 > 19.3x Combine like terms on the left

38.6 > 19.3x Divide by 19.3

38.6 / 19.3 > x

2 > x

What is<br> is 1/4 + 9/10y -3/5y +7/8 written in simplest form?

Leviafan [203]

Answer:

Step-by-step explanation:

$\frac{1}{4}+\frac{9}{10}y - \frac{3}{5}y+\frac{7}{8}\\\\=\frac{1}{4}+\frac{7}{8}+\frac{9}{10}y-\frac{3}{5}y\\\\$

Combine like terms. 1/4 and 7/8 are like terms and LCD of 4 and 8 is 8

9/10y and -3/5y are like terms and LCD of 10 , 5 is 10

$= \frac{1*2}{4*2}+\frac{7}{8}+\frac{9}{10}y-\frac{3*2}{5*2}y\\\\=\frac{2}{8}+\frac{7}{8}+\frac{9}{10}y-\frac{6}{10}y\\\\=\frac{9}{8}+\frac{3}{10}y$
