It has two what y equals so idk which one to solve or plug in(...I'm running out of points...)

Just plug in one of the other (doesn't matter which one) so it will look like
-3x+6=5x+38
or
5x+38=-3x+6 (it's the same thing as the first one)
Then you solve for x and you substitute that value so you can get y.
Hope this helped :)

You will equalize the two equations of y so
-3x+6=5x+38
5x+3x=38-6
8x=32
x=4
then you will substitute in the equation of y

$\sqrt[3]{27x} +\sqrt[3]{x} =3\sqrt[3]{x}+\sqrt[3]{x} =4\sqrt[3]{x}$

Good day and hoped that helped!

WILL MARK BRAINLY IF CORRECT!

bogdanovich [222]

Answer:

Step-by-step explanation:

The given equation is

$12( - \frac{1}{6}x - \frac{2}{3}y = - 5)$

$5( \frac{2}{5} x + \frac{1}{5} y = - 9)$

When we multiply we obtain the equations:

$- 2x - 8y = - 60$

$2x + y = - 45$

We add both equations to obtain:

$- 7y = - 105$

Divide both sides by -7 to get:

$y = \frac{105}{7} = 15$

Need help rn 30 points

Ilia_Sergeevich [38]

Answer: X = ( $-\frac{5}{4}\\$ , 6)

Step-by-step explanation:

x(4x - 19) = 30

4x^2 - 19x = 30

4x^2 - 19x - 30 = 0

ax^2 + bx + c = 0

$X{1}=$ $\frac{-b+\sqrt{b^{2} -4ac}}{2a}\\$ = $\frac{19+\sqrt{(-19)^{2} -4(4)(-30)}}{2(4)}\\$ = 6

$X{2}=$ $\frac{-b-\sqrt{b^{2} -4ac}}{2a}\\$ = $\frac{19-\sqrt{(-19)^{2} -4(4)(-30)}}{2(4)}\\$ = $-\frac{5}{4}$ = -1.25

X = ( $-\frac{5}{4}\\$ , 6)

Bob bought 16 packs of cola. Each pack had 8 cans. He drank 9 of the cans. How many cans are left?

grin007 [14]

Answer:

119 Cans Left

Step-by-step explanation:

If bob brought 16 packs of soda, and each pack had 8 cans, there would be 128 cans. This is because 1 pack is worth 8 cans.

16 × 8 = 128

128 - 9 = 119

Bob drank 9 of the cans, which is the same as subtracting from 128. This gives us the answer.
