Answer:

x=1

Step-by-step explanation:

you would substitute the first equation in for the y in the second equation

x + 2x+3 =6

then you would combine the x's

3x +3 = 6

Then you would move the 3 to the other side with the six

3x =6-3 3x = 3

Then finally you would divide the three

3x/3 = 3/3 x=1

Find the values of the mode when median is given to be 5 and mean is 7.

Reil [10]

Answer:

Mode = 1

Step-by-step explanation:

Relation between the Central Measures of Tendency

Mean, Median, and Mode are commonly referred to as the Central Measures of Tendency
The formula between the three is given by :
⇒ Mode = 3Median - 2Mean or Mode + 2Mean = 3Median

Solving

We know that :

Median = 5
Mean = 7

Therefore,

Mode = 3(5) - 2(7)
Mode = 15 - 14
Mode = 1

Find the value of x in the isosceles triangle shown below

egoroff_w [7]

Answer:

x = 10

Step-by-step explanation:

if there 2 same triangle then they are right triangle

By using Pythagorean theorem for 1 of right triangle, we have

$\sqrt{74} ^{2}$ = $7^{2}$ + $(\frac{x}{2}) ^{2}$

74 = 49 + $\frac{x^{2}}{4}$

74 - 49 = $\frac{x^{2}}{4}$

25 = $\frac{x^{2}}{4}$

therefore, x = $\sqrt{25*4}$ = $\sqrt{100}$ = 10
