Find two numbers whose sum is 20 and difference is 1

Mathematics

Divide 20 by 2
20/2 = 10
Add and subtract 0.5* from 10
10 + 0.5 = 10.5
10 - 0.5 = 9.5
Those two numbers are your answer.

*The reason why we used 0.5 because the difference is 1, so divide 1 by 2.

Have an awesome day! :)

One of the same-side exterior angles formed by two lines and a transversal is equal to 1/6 of the right angle and is 11 times sm
sergey [27]

One of the same-side exterior angles formed by two lines and a transversal is equal to 1/6 of the right angle and is 11 times smaller than the other angle. Then the lines are parallel

<h3><u>Solution:</u></h3>

Given that, One of the same-side exterior angles formed by two lines and a transversal is equal to 1/6 of the right angle and is 11 times smaller than the other angle.  

We have to prove that the lines are parallel.

If they are parallel, sum of the described angles should be equal to 180 as they are same side exterior angles.

Now, the 1st angle will be 1/6 of right angle is given as:

\begin{array}{l}{\rightarrow 1^{\text {st }} \text { angle }=\frac{1}{6} \times 90} \\\\ {\rightarrow 1^{\text {st }} \text { angle }=15 \text { degrees }}\end{array}

And now, 15 degrees is 11 times smaller than the other  

Then other angle = 11 times of 15 degrees

\text {Other angle }=11 \times 15=165 \text { degrees }

Now, sum of angles = 15 + 165 = 180 degrees.

As we expected their sum is 180 degrees. So the lines are parallel.

Hence, the given lines are parallel

1.3c = 16.9<br><br> What is c?<br><br><br><br> Solving Algebraic Equations with Multiplication
kirill [66]

1.3c = 16.9

To get C, divide both sides by 1.3

C = 16.9 / 1.3

C = 13

Answer:

they will have 32 baskets of fruit

1 hour

Step-by-step explanation:

andrews equation is y = x + 15

emilys equation is y = 3x + 13

when x = 1, andrew has 1+15 = 16, and emily has 3+13 = 16

What is (5x^2+x-3)-(-2^3+4)
SVETLANKA909090 [29]
I love this! :3

5x^2+x−3−(−2x^3+4)


5x^2+x+−3+−1(−2x^3)+(−1)(4)


5x^2+x+−3+2x^3+−4


(2x^3)+(5x^2)+(x)+(−3+−4)


And we're left with 2x^3+5x^2+x−7
