x = 56°

Step-by-step explanation:

Base angles of an isosceles triangle are equal.

This:

The angle of the triangle to our right, which is the third unequal angle = 180 - 2(31)

= 180 - 62

= 118°

The base angle of the triangle to our left = 180 - 118 (angles on a straight line)

= 62°

x = 180 - 2(62)

x = 180 - 124

x = 56°

There are 48 candies in a pack. Twelve are red. 18 are yellow. What is the ratio of reds to yellows?

Answers

Answer is 5:3

This means the ratio of reds to yellows is 5 to 3

=========================================================

Work Shown

We have 48 candies total and 18 yellow. This means there are 48-18 = 30 red assuming there are no other colors.

The ratio of red to yellow is 30:18. We simply list the number of reds (30), followed by a colon, then the number of yellows.

(number of red):(number of yellow)

The order is important. We cannot swap the items. This is because "reds to yellows" in the instructions has "red" come first.

Once you have the ratio 30:18, you divide both parts by the GCF 6 and you'll end up with the final answer 5:3

So for every 5 red candies we have 3 yellow candies. We can say "the ratio of reds to yellows is 5 to 3".

A photographer charges $25 to travel to a client's location, plus $55 per hour for her
services. What is the duration, in hours, of a photography session that costs $465?

Answers

Answer:

8 Hours

Step-by-step explanation:

First, you have to subtract the 25$ because we already know that that is a stable value (meaning it will not change)

Then, you have to divide 440 by 55 to get an answer of 8 hours for the session :D

To find total multiply 55 by number of hours (h) and then add 25:

Total = 55h + 25

Given the total solve for h:

465 = 55h + 25

Subtract 25 from both sides

440 = 55h

Divide both sides by 55

H = 440/55

H = 8

It was 8 hours

Answer:

x is equal to both 3 and 6.

Step-by-step explanation:

[tex]\sqrt{x - 2} + 4 = x\\\sqrt{x - 2} = x - 4\\x - 2 = (x - 4)^2\\x - 2 = x^2 - 8x + 16\\x^2 - 9x + 18 = 0\\(x - 3)(x - 6) = 0\\[/tex]

So x values of 3 and 6 will make this statement true.
