Answer:

Step-by-step explanation:

X - 3(2x - 7) = 76

Opening bracket

X - 6X + 21 = 76

-5X = 76 - 21

-5X = 55

X = 55/-5

X = -11

Answer:

To solve this equation your goal is to get x by itself

First we need to distribute the 3 through the (2x-7)

x-6x+21=76 (-3*2x=-6x, -7*-3=21)

Your next step is to combine like terms

-5x+21=76 (x-6x=-5x)

Next subtract 21 from both sides

-5x=55 (21-21=0, 76-21=55)

Last you need to divide both sides by -5

x=-11 (-5/-5=1, 55/-5=-11)

x=-11

Hope this helps ;)

Solve for y 16y^2-25=0

Pepsi [2]

Answer:

$\large\boxed{x=-\dfrac{5}{4}\ \vee\ x=\dfrac{5}{4}}$

Step-by-step explanation:

$16y^2-25=0\\\\METHOD\ 1:\\\text{use}\ a^2-b^2=(a-b)(a+b)\\\\16=4^2\ \text{and}\ 25=5^2\ \text{therefore we have}\\\\4^2y^2-5^2=0\\\\(4y)^2-5^2=0\\\\(4y-5)(4y+5)+0\iff4y-5=0\ \vee\ 4y+5=0\\\\4y-5=0\qquad\text{add 5 to both sides}\\4y=5\qquad\text{divide both sides by 4}\\\boxed{y=\dfrac{5}{4}}\\\\4y+5=0\qquad\text{subtract 5 from both sides}\\4y=-5\qquad\text{divide both sides by 4}\\\boxed{x=-\dfrac{5}{4}}$

$METHOD\ 2:\\\\16y^2-25=0\qquad\text{add 25 to both sides}\\\\16y^2=25\qquad\text{divide both sides by 16}\\\\y^2=\dfrac{25}{16}\to y=\pm\sqrt{\dfrac{25}{26}}\\\\y=-\dfrac{\sqrt{25}}{\sqrt{16}}\ \vee\ x=\dfrac{\sqrt{25}}{\sqrt{16}}\\\\\boxed{y=-\dfrac{5}{4}\ \vee\ x=\dfrac{5}{4}}$

An oil tanker empties at 3.5 gallons per minute. Convert this rate to cups per second. Round to the nearest tenth.

ss7ja [257]

If given ratio is 3.5 gallons per minute and we want to cups per second we can do this knowing that
1 gallon= 16cups
1min = 60sec
ratio=3.5 $\frac{gallon}{minute}=3.5* \frac{16cups}{60 seconds} =3.5*0.266=0.933 \frac{cups}{sec}$
Its the result

If a square has a length of 3x-y, what is its area?

SVEN [57.7K]

Answer:

9x² -6xy +y²

Step-by-step explanation:

The square of the binomial can be written directly using the relationship ...

(a +b)² = a² +2ab +b²

where you have a=3x and b=-y.

area = (3x -y)² = (3x)² + 2(3x)(-y) + (-y)²

area = 9x² -6xy +y²
