Since the angles are equal, the sides will be equal. Set 19=3x-2 and solve. Add 2 to both sides and get 3x=21, divide both sides by three and x=7.

Two numbers are 10 units away in different directions from their midpoint, m, on a number line. The product of the numbers is –9

irinina [24]

In my opinion the answer is m2 – 100 = –99
proof
m2 – 100 =(m – 10)(m + 10)
for eg. m=1, (-9)(11)= –99

Jorge wrote the equation -6 + 4x=8 . What is the value of x? -4 -2 4 2

astraxan [27]

Answer:

$\text{Thus the value of x = }\frac{7}{2}$

Step-by-step explanation:

The equation is given to be : -6 + 4x = 8

Now, we need to solve this equation in order to find the value of x

⇒ -6 + 4x = 8

Adding +6 on both the sides

⇒ -6 + 4x + 6 = 8 + 6

⇒ 4x = 14

dividing each term by 4

$\implies\frac{4x}{4}=\frac{14}{4}\\\\\implies x=\frac{7}{2}$

$\text{Thus the value of x = }\frac{7}{2}$
