<span>seven less than (-7) than the product of twice a number (2x) is greater than (>) five more than (+5) the same number (x)

2x-7>x+5
treat the > sign as an equals for now
2x-7=x+5
subtract x from both sides
x-7=5
add 7 to both sides
x=12
put the > sign back in
x>12</span>

Let the number be  x.

Seven less than the product of twice a number :  2x  -  7.
Greater than                                                                  >
5 more than the same number                            :    x + 5

The equation  is:                                            2x - 7   >  x + 5.

That's the answer. But let us just go ahead and solve it.

2x - 7  >  x + 5.
2x - x >  5 + 7       
x  >  12.

algol13

Answer:

66

Step-by-step explanation:

105+420=525   (Total Money)

7x3.25=22.75   (Cost of all bracelets)

8x11.74=93.92   (Cost of all necklaces)

93.92+22.75=116.67   (Cost of all Christmas presents)

525-116.67=408.33   (Total money - Cost of all Christmas presents)

408.33/6.15=66.39...   (Amount of necklaces)

since in real life you can only buy a whole number of things, you would round down 66.39 to 66. I hope this helped!

I need help with #39-42, please explain.

For question 39 & 40, we need to use the below equation to complete the sentence

l=m\sqrt{n}

Question 39:

When ' n ' increase, the \sqrt{n} will also increase and that multiplied with constant ' m ', the l will also increase.

Solution for question 39:

As n increases and m stays constant , l <u>increases</u>

-------

Question 40:

Solving the equation for m, we get

l = m\sqrt{n} \\ \\ m=\frac{l}{\sqrt{n}}

When ' l ' increases, the numerator increase, the denominator stays constant because 'n' stays constant, for this condition, the fraction increases.

Solution for question 40:

As l increase and n stays constant, m <em><u>increases</u></em>

------

For question 41 & 42, we need to use the below equation to complete the sentence

r=s^2/t^2

Question 41:

When s is triped, the equation will be...

r=(3s)^2/t^2=\frac{3^{2}s^{2}}{t^2}   =9s^2/t^2

Solution for question 41:

If s is tripled and t stays constant, r is multiplied by <em><u>9</u></em>

--------

Question 42:

When t is doubled, the equation will be...

r=s^2/(2t)^2=\frac{s^2}{2^2 \cdot t^2}=\frac{s^2}{4t^2}\\   \\ r=0.25s^2/t^2 \; \; (or) \; \; \frac{1}{4} \cdot \frac{s^2}{t^2}

Solution for 42:

If t doubled and s stays constant, r is multiplied by <em><u>1/4 or 0.25</u></em>

Use the arc length formula and the given information to find r.. s = 16 cm, θ = 48°; r = ?
saveliy_v [14]

Answer:

The value for r is 19.1 cm

Step-by-step explanation:

We have been given that  s = 16 cm, θ = 48° and we have to find the radius r.

We know the relation

\theta=\frac{s}{r}\\\\r=\frac{s}{\theta},\text{ where }\theta \text{ is in radian}

Hence, first of all convert the angle in radian

θ = 48°= 0.837758 radian

Therefore, we have

r=\frac{16}{0.837758}\\\\r=19.1\text{ cm}
