Chill dude.                          

Stop with the all caps.    

25 is the answer.

G = green sweets

Ratio of blue to green = 3:5

Ratios are essentially fractions, and can be converted into fraction form

Therefore, number of blue sweets is 3/5 of green sweets, which can also be represented as 3/5g

Number of green sweets to red sweets is 6:1

We can also flip this ratio around and the ratio would still have the same value.

Number of red sweets to green sweets = 1:6

In fraction form, the number of red sweets is 1/6 of green sweets, which is also 1/6g.

Since there are less than 270 sweets in the box, we can use this expression to represent the sweets in the box:

G + 3/5g + 1/6g < 270

Find a common denominator for the fractions.

5 * 6 = 30, thus a common denominator would be 30.

Since G is a variable with no coefficient, 1 would be implied because no coefficient is present.

So when multiplying G to get a common denominator, the numerator would be 30. 30/30 = 1

G * 30 = 1 * 30

G = 30/30g

Multiply the rest of the numerators and you’ll get:

30/30g + 18/30g + 5/30g < 270

Add.

1 + 18/30g + 5/30g = 1 23/30g

Convert this into an improper fraction.

53/30g < 270

Now divide both sides by 53/30.

(53/30g) ÷ (53/30) < 270 ÷ (53/30)

= g < 270 ÷ (53/30)

Dividing fractions is complex, so you can simply switch the numerator and denominator and multiply:

G < 270 x (30/53)

= g < 8,100/53

Since the number of red sweets to green sweets is 1/6g the number of green sweets, the number of red sweets is 1/6 of 8,100/53.

R = red sweets

R < 8,100/53 x 1/6

8,100 x 1 = 8,100

53 x 6 = 318

R < 8,100/318

318 goes into 8,100 25 times, regardless of any remainder.

Therefore, the greatest possible number of red sweets in the box is 25 red sweets.

Use the angle relationship to find the value of x.

Answers

Answer:

Hello! answer: x = 11

Step-by-step explanation:

These are vertical angles in simple terms meaning they are across from each other and if you folded them over each other they would match up and they will equal the same measure so 13 × 11 = 143 143 - 10 = 133 therefore x = 11 Hope that helps!

X = 11
Both of those angles are equal to each other, so 133= 13x-10, add 10 from both sides to cancel out the “-10”. You get 143=13x and then divide both sides by 13 and you get x= 11

How do I create an equation and solve for x

Answers

Answer:

Equation: (2x + 30) + 106 = 180

x = 22°

Step-by-step explanation:

We know that the missing angle from within the triangle and the expression 2x + 30 makes 180 so we can say;

180 - (33 + 41) = missing angle

180 - 74 = missing angle

106° = missing angle

Now we can set up our equation to solve for x:

(2x + 30) + missing angle = 180°

(2x + 30) + 106 = 180° => This would be our equation:

Now let's solve:

2x + 30 + 106 = 180°

2x + 136 = 180

2x = 180 - 136

2x = 44

x = 44/2

x = 22°

Hope this helps!

Answer:

x = 22

Step-by-step explanation:

To solve this the first thing you would need to do is solve the angle that is unmarked in the triangle. To do this you would use the knowledge that the interior agnles of triangles alwasy equal to 180 degrees.

In this case, you would add 33 + 41 = 74 and then you would

subtract 180 - 74 = 106

The next step would be to find the question mark 2x + 30 =  ?

To do this you would have to use the 106 degrees from the previous step.

Knowing that (2x + 30) + 106 = 180 degrees this should be easy to solve.

(the angles on either side of a line that is split always add to equal 180 degrees)

You would then subtract 180 - 106 = 74

Now we know that 2x + 30 = 74

Now you would subtract 30 fom both sides to find that 2x = 44

All you have to do now is divide each side by to find that x = 22
