How to turn negative into mixed numbers into improper fractions

1 answer:

4 0

U turn negative numbers from mixed numbers to improper fractions the same way u do with positive...u just temporarily disregard the negative sign.

Example :
- 2 2/3.....temporarily disregard the negative sign......take ur whole number (2) and multiply it by ur denominator (3) giving u 6, then add that to ur numerator (2) giving u 8....then put that number over the original denominator (3) giving u 8/3...and then put back ur negative sign...-8/3

What is the solution to the system of equations? (7, 4) (7, startfraction 13 over 3 endfraction) (8, startfraction 14 over 3 end

miss Akunina [59]

The points are (7, 13/3).

Lets simplify the equation,

The equation of first line: y = 1/3 x + 2

the equation of second line: y= 4/3x - 5

Solve the system of equations by elimination,

Multiply equation A by -4 both sides

-4y = -4(1/3x +2)

-4y = -4/3x-8

After eliminating the equation we get,

y = 13/3

So now have to find x

13/3 = 1/3x + 2

Lets multiply above by 3
x = 13-6

x = 7.

Hence the points are (7, 13/3)

Find the arc length of the remaining portion if the bolded section was cut out of the circle. Round to the nearest tenth.

jeka94

Answer:

69.6 ft

Step-by-step explanation:

The arc length can be found as a fraction of the circumference. That fraction is the ratio of the central angle measure to the measure for the whole circle.

Central angle of remaining arc:

360° -150° = 210°

Fraction of full circumference:

210°/360° = 7/12

The circumference of the circle is ...

C = 2πr = 2π(19 ft) = 38π ft.

Then the length of the remaining arc is ...

(7/12)(38π) ft ≈ 69.6 ft

Question in the photo<br> Pls help

ra1l [238]

Answer:

F = $\frac{9C+160}{5}$

Step-by-step explanation:

Given

C = $\frac{5(F-32)}{9}$ ( multiply both sides by 9 to clear the fraction )

9C = 5(F - 32) ← distribute

9C = 5F - 160 ( add 160 to both sides )

9C + 160 = 5F ( divide both sides by 5 )

$\frac{9C+160}{5}$ = F
