Answer:

True

Step-by-step explanation:

$\begin{cases} y = 3x \\\\ 2y + 2x = 24\end{cases}$

Plugging y = 3x in the equation 2y + 2x = 24, we find:

2(3x) + 2x = 24

6x + 2x = 24

8x = 24

x= 24/8

x = 3

Plugging x = 3 in the equation y = 3x we have:

y = 3*3 = 9

(x, y) = (3, 9)

Answer:

t = 13

Step-by-step explanation:

By the definition of an isosceles triangle,

Two sides of the isosceles triangle ABC will be equal in measure.

Therefore, AC = BC

Equation for the value of 't' will be,

(2t + 5) = (3t - 8)

3t - 2t = 5 + 8

t = 13

Therefore, t = 13 will be the answer.

Hey there !

$\dfrac{3}{2} = \dfrac{3}{2x} - \dfrac{6}{5x} \\ \\ \dfrac{3}{2} = \frac{15 - 12}{10 {x}^{} } \\ \\ \frac{1}{2} = \frac{1}{10x} \\ \\ x = \frac{1}{5} \: \: \: \: \: \: \: \: Ans.$
Hope it helps you :)

Find the solution to the system of equations given below:<br> x=-4<br> -5x-4y=16<br><br> PLS HELP

poizon [28]

Answer:

Step-by-step explanation:

Since x=-4 plug in the -4 into the equation to find y,

-5(-4)-4y=16

20-4y=16 -20 -20 __________

-4y=-4

-4y/-4=-4/-4

___________

y=1

So now you found both x and y so plug in both now to check if both are correct.

-5(-4)-4(1)=16

20-4=16

16=16

So both y and x are correct.

Hope this helps!:)
