Can you guys help me

Fudgin [204]

Answer:

The answer is 76.

Step-by-step explanation:

≅ means to be equal to.

☆Angle DGE ≅ EGF.

Therefore, 3x + 8 = 5x - 12

☆Let's solve that equation.

$3x + 8 = 5x - 12 \\ \frac{ - 5x \: \: \: \: \: \: \: = - 5x \: \: \: \: \: \: \: \: }{ - 2x + 8 = - 12} \\ \frac{ \: \: \: \: \: \: \: \: - 8 = - 8}{ \frac{ - 2x}{ - 2} = \frac{ - 20}{ - 2} } \\ x = 10$

We found the value of x which is 10.

☆Let's Now plug in.

$DGE \\ 3x + 8 \\ 3(10) + 8 \\ 30 + 8 \\ 38$

and the other:

$EGF \\ 5x - 12 \\ 5(10) - 12 \\ 50 - 12 \\ 38$

☆They asked for what the angle of DGF measured. So we would have to add both sides

$38 + 38 = 76$

☆The answer is 76

What is the range of the data? 99.7, 101.8, 103.6,98.6, 100.2, 102.9

erik [133]

Answer:

5.0

Step-by-step explanation:

The data in order looks like so:

98.6, 99.7, 100.2, 101.8, 102.9, 103.6

Take the greatest value and subtract it from the least value to get the range of the data:

103.6-98.6=5

5 is your answer

Hope this helps!

Need help with number 3 inequalities with variables on both sides

Volgvan

Answer:

x ≤ 2

Step-by-step explanation:

We are given the inequality:

$\displaystyle{2x-3 \leq \dfrac{x}{2}}$

First, get rid of the denominator by multiplying both sides by 2:

$\displaystyle{2x\cdot 2-3\cdot 2 \leq \dfrac{x}{2}\cdot 2}\\\\\displaystyle{4x-6 \leq x}$

Add both sides by 6 then subtract both sides by x:

$\displaystyle{4x-6+6 \leq x+6}\\\\\displaystyle{4x \leq x+6}\\\\\displaystyle{4x-x \leq x+6-x}\\\\\displaystyle{4x-x \leq 6}\\\\\displaystyle{3x \leq 6}$

Then divide both sides by 3:

$\displaystyle{\dfrac{3x}{3} \leq \dfrac{6}{3}}\\\\\displaystyle{x \leq 2}$

Therefore, the answer is x ≤ 2
