What is a correct first step in solving the inequality –4(3 – 5x)≥ –6x + 9?

The first thing you would need to know is PEMDAS. Also stands for parenthesis, exponents, multiplication, division, addition and subtraction.
This shows the order you should follow when solving problems like these.

This problem states that the first thing that you would look for is parenthesis. There are parenthesis in this statement, but there's a number before the parenthesis. In this case, your first step would be to take -4(3) - -4(-5x)
The first step is using distributive property to -4(3-5x) to get
-4(3) - (-4)-5x

Complete the Square:<br> 5x^2+16x-40=8<br> (please show your steps)

Sav [38]

Answer:

Step-by-step explanation:

divide through by the coefficient of $x^{2}$

$\frac{5x^{2} }{5}$ + $\frac{16x}{5} + \frac{-40}{5} = \frac{8}{5}$

$x^{2} +\frac{16}{5}x -8 =\frac{8}{5}$

$x^{2} +\frac{16}{5} x = \frac{8}{5} +8$

$x^{2} + \frac{16}{5} x =\frac{48}{5}$

Add half of the square of the coefficient of x to both sides $(\frac{1}{2} X \frac{16}{5} ) ^{2}$

$x^{2} + \frac{16}{5}x + (\frac{1}{2} X \frac{16}{5} )^{2} =$ $\frac{48}{5} +(\frac{1}{2} X \frac{16}{5} )^{2}$

$x^{2} +\frac{16}{5} x +(\frac{16}{10}) ^{2} =\frac{48}{5} +\frac{64}{25}$

$(x +\frac{16}{10})^{2} =\frac{304}{25}$

$x +\frac{16}{10} =$ ± $\sqrt{\frac{304}{25} }$

$x = -\frac{16}{10}$ ± $\sqrt{\frac{304}{25} }$

$x=-\frac{16}{10} + \sqrt{\frac{304}{25} }$ or $-\frac{16}{10} - \sqrt{\frac{304}{25} }$

$x = 1.89$ or -5.09

The gasoline gauge on a van initially read one third

Zigmanuir [339]

3/4 - 1/3 = 9/12 - 4/12 = 5/12

(5/12) / 10 = 1 / x
5/12x = 10
x = 10* 12/5
x = 120/5 = 24 gallons...so when full, the tank holds 24 gallons

so if it is already 3/4 full, then u just need 1/4 to fill
1/4(24) = 24/4 = 6......so u would need 6 more gallons to fill the tank up to full capacity.

What is 59,468 to the place of 9 the underlined digit

Diano4ka-milaya [45]

59,468

9 is in the thousands place

If you want to round, look at the hundreds place value. It is a 4. Because 4 is less than 5, round down.

59,000 is your rounded

hope this helps
