Answer:

Simplifying

2x + -10y = 15

Solving

2x + -10y = 15

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10y' to each side of the equation.

2x + -10y + 10y = 15 + 10y

Combine like terms: -10y + 10y = 0

2x + 0 = 15 + 10y

2x = 15 + 10y

Divide each side by '2'.

x = 7.5 + 5y

Simplifying

x = 7.5 + 5yStep-by-step explanation:

Answer:

$x < - \frac{5}{13}$

$x \geqslant - \frac{1}{5}$

Step-by-step explanation:

$- \frac{13}{16}x + \frac{3}{8} < \frac{11}{16} \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: \: - \frac{3}{8 } < - \frac{3}{8} }{ \frac{ - \frac{13}{16}x }{ - \frac{13}{16} } < \: \: \: \frac{ \frac { 5}{16} }{ - \frac{ 13}{16} } } \\ \\ x < \frac{ - 5}{ \: 13}$

↷

$\frac{1}{3} \geqslant \frac{2}{9} - \frac{5}{9} x \\ \frac{ - \frac{ 2}{9} \geqslant - \frac{2}{9} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }{ \frac{ \: \: \: \frac{1}{9}x }{ - \frac{ 5}{9} } \geqslant \frac{ - \frac{5}{9} }{ - \frac{5}{9} } } \\ \\ x \geqslant - \frac{1}{5}$

The value of is between 4.7 and 4.8. Which of the following is a more precise approximation of ?

Nataly_w [17]

Answer: D. between 4.79 and 4.8

Step-by-step explanation:

The square root of 23 (√23) is 4.79583152331. We can obviously eliminate A and B. C and D is left. C is wrong because if we approximate the square root of 23, which is 4.79583152331, we get 4.79. 4.79 > 4.78, so it can't be C. Hope this helps :)

Help me please please

harina [27]

Answer:

$EH = \sqrt{HG^2+EG^2} = \sqrt{4^2+6^2} = \sqrt{16+36} = \sqrt{52} = 2\sqrt{13}$

EG² = GH*GF
EG² = 4*12
EG² = 48
EG = √48 = 4√3
