If four times the sum of a number and 5 is divided by 3, the result is 16. Step 1. Let x be the number.
Step 2. Four times the number and 5 is divided by 3
Step 3. The result is 16
Step 4. Multiply by 3 to both sides of equation to get rid of denominator
Step 5. Subtract 20 from both sides of equation
Step 6. Divide by 4 to both sides of equation
Step 7 ANSWER is x=7.
I hope the above steps were helpful.
Answer:There are infinity equivalent fractions to 424
Step-by-step explanation:
Answer:
(x-7) (x^2-5)
Step-by-step explanation:
x^3-7x^2-5x+35
Factor out an x^2 from the first two terms and -5 from the last 2 terms
x^2 (x-7) -5(x-7)
Factor out (x-7)
(x-7) (x^2-5)
<span>First of all, there should be coherence for the units of measurement -- either they are all meters or they are all ft. I would assume they are all ft.
The correct answer is 75 ft above. T
The explanation is the following: suppose the ground level is the x-axis, the 2 feet of the arch lie respectively on (0,0) and (100,0) on the ground level. Since the arch is 100ft high, the vertex of the parabola will be the point (100,100). Thus, we can find the equation describing the parabola by putting the three points we know in a system and we find that the equation of the parabola is y=(-1/100)x^2+2
To find the focus F, we apply the formula for the focus of a vertical axis parabola, i.e. F(-b/2a;(1-b^2+4ac)/4a).
By substituting a=-1/100, b=2 and c=0 into the formula, we find that the coordinates of the focus F are (100,75).
So we conclude that the focus lies 75ft above ground.</span>
