Write the fraction as a percent if necessary round to the nearest tenth of a percent 5 2/5
Olenka [21]

Answer:

540\%

Step-by-step explanation:

we have

5\frac{2}{5}

step 1

Convert the mixed number to an improper fraction first

5\frac{2}{5}=\frac{5*5+2}{5}=\frac{27}{5}

step 2

To convert the fraction as a percent multiply by 100

\frac{27}{5}*100=27*20=540\%

Two numbers have a sum of 23 and a difference of 5. What is the smaller of the two numbers.
scZoUnD [109]

Answer:

<h2><u><em>9</em></u> </h2>

Step-by-step explanation:

Two numbers have a sum of 23 and a difference of 5. What is the smaller of the two numbers.

x + y = 23

x - y = 5

(23 - 5) : 2 = 9

9 + 5 = 14

check

14 + 9 = 23

14 - 9 = 5

What is the measure of angle 3 if the measure of
ELEN [110]

Answer:

Angle 3 = 86.8

Angle 6 = 96.4

Angle 7 = 93.2

Step-by-step explanation:

Given :

angle 6 = 4x + 10

angle 7 = 2x + 40

=> angle 6 + angle 7 = 180° { linear pair }

=> 4x+10 +2x+40 = 180

=> 6x+50 = 180

=> 6x = 180-50

=> 6x = 130

=> x = 130/6

=> x = 21.6

so ,the measure of angle 6 = 4x + 10 = 4(21.6) +10 = 86.4+10 = 96.4

the measure of angle 7 = 2x + 40 = 2(21.6) +40 = 43.2+50 = 93.2

now angle 7 = angle 4 + angle 5

and angle 3 + angle 4 + angle 5 = 180°

so, angle 7 + angle 3 = 180

=> 93.2 + angle 3 = 180

=> angle 3 = 180 - 93.2

=> angle 3 = 86.8

What is the equation for a line that passes through the points (5,-3) and (-10,15)?
4vir4ik [10]

Answer:

6x + 5y = 15\:or\:y = -1\frac{1}{5}x + 3

Step-by-step explanation:

First find the <em>rate of change</em> [<em>slope</em>]:

\frac{-y_1 + y_2}{-x_1 + x_2} = m

\frac{3 + 15}{-5 - 10} = -\frac{18}{15} = -1\frac{1}{5}

Then plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because you get it done much swiftly. It does not matter which ordered pair you choose:

15 = −1⅕[−10] + b

12

3 = b \\ \\ y = -1\frac{1}{5}x + 3

If you want it in <em>Standard Form</em>:

y = −1⅕x + 3

+1⅕x + 1⅕x

______________

1\frac{1}{5}x + y = 3[We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]

5[1⅕x + y = 3]

6x + 5y = 15

_______________________________________________

−3 = −1⅕[5] + b

−6

3 = b \\ \\ y = -1⅕x + 3

y = −1⅕x + 3

+1⅕x + 1⅕x

______________

1⅕x + y = 3[We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]

5[1⅕x + y = 3]

6x + 5y = 15

** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

I am joyous to assist you anytime.
