If 2x-4(3-x)=18, then x=_____? Can someone please help me with this problem

denis-greek [22]

Answer:

Answer is below

Step-by-step explanation:

Simplify both sides of the equation.

$2x-4(3-x)=18\\2x+(-4)(3)+(-4)(-x)=18$

DIstribute

$2x+-12+4x=18\\(2x+4x)+(-12)=18$

CLT

$6x+-12=18\\6x-12=18$

Add 12 to both sides.

$6x-12+12=18+12\\6x=30$

Divide both sides by 6.

$\frac{6x}{6} =\frac{30}{6}\\ x=5$

A right triangle has legs of length 136 cm and 119 cm. What is the length of the hypotenuse of the right triangle? Enter the ans

geniusboy [140]

Answer:

Hypotenuse= 180.7 cm

Step-by-step explanation:

Using Pythagoras' theorem:

a^2+b^2=c^2 (let c= Hypotenuse "H")

(136)^2 + (119)^2 = H^2

18496+14161 =H^2

H^2= 32657

Taking square root on both sides

$\sqrt{H}$ = $\sqrt{32657}$

H=180.7

(b) we often read that iq scores for large populations are centered at 100. what percent of these 78 students have scores above

zheka24 [161]

Given that the<span> iq scores for large populations are centered at 100.

To get what percent of these 78 students have scores above 100 we conduct a normal distribution probability of the data.

P(x > 100) = P(z > (100 - 100)/sd) = P(z > 0) = 1 - P(z < 0) = 1 - 0.5 = 0.5 = 50%
