Answer:

$x > - \frac{20}{21}$

Step-by-step explanation:

-5/2 × (3x + 4) < 6x - 3x

-15/2x - 10 < 3x

-15x - 20 < 6x

-15x - 6x < 20

-21x < 20

x > -20/21

Answer:

$\tt{}x > -\frac{21}{20}$

Step-by-step explanation:

$\tt{} - \frac{5}{2} \times (3x + 4) < 6x - 3x$

$\tt{}- \frac{5}{2} x - 10$

$\tt{}- 15x - 20 < 6x$

$\tt{}- 21x = 20$

$\tt{}x > -\frac{21}{20}$

Solve the simultaneous equation: 5 x + 2 y = 25 5 x − y = 10

Liono4ka [1.6K]

Answer:

(x, y) = (3, 5)

Step-by-step explanation:

$5x+2y=25\\5x-y=10$

Solving by elimination here again, there are 2 good options available. Either multiply the whole bottom equation by -1 to cancel the x, or by 2 to cancel the y. I'll do the latter:

$5x+2y=25\\\\2(5x-y=10)\\10x-2y=20$

Add from top to bottom:

$\rightarrow (5x+10x)+(2y-2y)=25+20\\\rightarrow 15x=45\\\rightarrow x=3$

Now, with the value of x, solve for y in either of the equations. I'll choose the second one here:

$\rightarrow 5x-y=10\\\rightarrow 5(3)-y=10\\\rightarrow 15-y=10\\\rightarrow -y=-5\\\rightarrow y=5$

(x, y) = (3, 5)

Brennan has already run 16 miles on his own, and he expects to run 3 miles during each track practice. How many track practices

pentagon [3]

Answer:

It would take Brennan 4 track practice runs.

Step-by-step explanation:

He has already run 16 miles and needs to run 28 in total. If we are counting the 16 in the 28 miles, he would need to run only 12 more to reach his goal. And if he runs 3 miles a run, it would take him about 4 runs to finish his 28-mile goal.

(28-16=12 and 12/3=4)
