4x - 6
Step-by-step explanation:
6 less is -6
product of four and a number x is 4x
Answer:
C (48)
explanation:
firstly, divide 384 by 80. This gives you 4.8. So, since 10 out of every 80 students are left handed we have to times 4.8 by 10 which gives you 48.
You have an angle of elevation of 3 degrees and you're 2000 ft from base of 30 story building.
<span>Draw a picture of this. Then tan(3) = ht of bldg/2000 </span>
<span>I get a height of 104.82 ft rounded to 2 dp. </span>
<span>5. Ok. use the Pythagorean Theorem here to find the hypotenuse of the right triangle </span>
<span>hypt = sqrt(50^2 + 9^2) </span>
<span>Now sine of the angle of elevation is 50/hypt. = 0.984 or 0.98 to 2 dp.</span>
4400% increase
1800000-40000/40000 = x/100
1760000/40000 = x/100
176*25/4*25 = x/100
X= 4400% increase
If g(x) is equal to f(x), then they are the same value.
Put 5.5x - 13 in place of g(x) in the second equation.
5.5x - 13 = -5x + 18.5
Add 13 to both sides.
5.5x = -5x + 31.5
Add 5x to both sides.
10.5x = 31.5
Divide 10.5 on both sides.
x = 3
Hope this helps! :)
