5/6y-9=1/6y-5

What’s y

Answers

Answer:

y=4/6

Step-by-step explanation:

Step 1: Add 9 to both sides.

   5/6y -9 = 1/6y -5

     5/6y = 1/6y +4

Step 2: Subtract 1/6 to both sides.

   5/6y= 1/6+4

          y=4/6

If you are confused still, 5/6 - 1/6 is 4/6. Remember signs matter, because if the original equation was 5/6y -9 = -1/6y -5 the answer would be y= 4!

An angle measures 86° less than the measure of its complementary angle. What is the measure of each angle?

Answers

[tex]x + (x - 86) = 90[/tex]

[tex]2x - 86 = 90[/tex]

Both sides plus 86

[tex]2x = 90 + 86[/tex]

[tex]2x = 176[/tex]

Divided both sides by 2

[tex]x = \frac{176}{2} \\ [/tex]

[tex]x = 88[/tex]

So the angles are :

[tex]88 \: \: \: \: \: and \: \: \: \: 2[/tex]

The measure of the two complementary angles are 88° and 2°.

What is a complementary angle?

"When the sum of two angles is 90°, then the angles are known as complementary angles."

Let, the complementary angle of the mentioned angle is x.

Therefore, the angle is = (x - 86°)

Now, x + (x - 86°) = 90°

⇒ 2x - 86° = 90°

⇒ 2x = 176°

⇒ x = 88°

Therefore, the measured angle is 88°.

It's complementary angle is = (90° - 88°) = 2°.

Jim and his friends are going to the Del Mar Fair and find they have two ticket options. In one option each person could buy an admission ticket for $5 and then pay $0.25 for each ride. The other option is to buy an admission ticket for $2 and then pay $0.75 a ride. What do you think Jim should do?

Answers

Step-by-step explanation:

let the cost of the options be y

since they are two already we can model the cost as

For the first ticket option

y=5+0.25(2)

y=5+0.5

y=$5.5

For the second ticket option

y=2+0.75(2)

y=2+1.5

y=$3.5

They should go for the second ticket option since it is $2 less than the first option
