Step-by-step explanation:

180° is x+2x

so 180° is 3x

180°/3 is 60°

so x is 60° and 2x is 120°

Answer:

1/5 = 0.2 so, she can drink 0.1 of a gallon each day

to turn a fraction into a decimal you should do..

1/5 since 5 can't go into 1 you add a 0 to the 1 making it a 10 and move the decimal point, since 5 goes into 10, 2 times, we get 0.2

Answer:

x=15/4,y=-8.25

Step-by-step explanation:

Well to begin with it make both y's equal so multiply the first equation by 3 making it into: 6.6x+3y=-12. next subtract this new equation by the other one making it one equation as, 1.6x=-6, simplify to get: x=15/4, or 3.75 input that into one of the equations the secound one would be easier to make it 18.75+3y=-6 simplify again, 3y=-24.75 than you get y as y=-8.25

Answer:

B

Step-by-step explanation:

Multiply each ratio by the same number

4x3=12 7x3=21

The number of players on each team could be; B. 12 soccer players and 21 baseball players.

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b. Remember that the ratio should always be taken of quantities with the same unit of measurement. Also, the ratio is a unitless(no units) quantity.

We have been given that the ratio of soccer players to baseball players on two school teams is 4 to 7.

That is; 4: 7

Then Multiply each ratio by the same number.

4 x 3 = 12

7 x 3 = 21

Therefore, the number of players on each team could be; B. 12 soccer players and 21 baseball players.

Answer:

x=50

Step-by-step explanation:

A= 30+2x

B= x

Supplementary angles are angles that always add up to 180 degrees.

therefore, A + B=180 degrees

30 + 2x + x = 180: Now we solve

30 + 3x =180

subtract 30 from both sides

3x=150

divide by 3

3x/3 = 150/3

x= 50

Answer:

Infinite solutions

Step-by-step explanation:

I converted y + 2 = -5x into y=-5x-2

The two equation are the same (coinciding lines) and therefore have the same points and they have an infinite amount of solutions.

Answer:

50°

Step-by-step explanation:

angle 5 = angle 4 ( Alternative Interior Angles are equal )

But angle 3 & angle 4 are linear pairs. So,

angle 3 + angle 4 = 180°

=> angle 3 + angle 5 = 180° (angle 5 = angle 4)

=> angle 3 + 130° = 180°

=> angle 3 = 180° - 130° = 50°

Answer:

I would choose a coin from the case containing half gold coins and half silver coins, because if you get a gold coin then you are going to know the chest only contains cold coins. From this we can deduce that the chest marked silver coins is really the 50/50, and the chest marked gold is really silver.  Step-by-step explanation:

Answer:

x = -7

Step-by-step explanation:

4x - 9 = 7x + 12

~Add 9 to both sides

4x = 7x + 21

~Subtract 7x to both sides

-3x = 21

~Divide -3 to both sides

x = -7

Best of Luck!

Answer:

x = -7

Step-by-step explanation:

Combine like terms: (Subtract 4x from both sides, and subtract 12 from both sides)

4x - 9 = 7x + 12

-9 - 12 = 7x - 4x

-21 = 3x

Divide by 3:

-21 = 3x

x = -21 / 3

x = -7

Plug in to check your answer:

4x - 9 = 4(-7) - 9 = -37

7x + 12 = 7(-7) + 12 = -37

Answer:

26.25 minutes

Step-by-step explanation:

Given that :

Number of pages (p) read by Elias can be modeled by the function ;

p = 45m + 18

Where P = Number of pages ; m = number of minutes

Number of minutes it will take to read a total of 39 pages

p = 4/5m + 18

39 = 4/5m + 18

39 - 18 = 4/5m

21 = 4/5m

4m = 21 * 5

4m = 105

m = 105 / 4

m = 26.25

Answer:

Part 1: Number of extra round balloons that long balloons = 12 balloons

Part 2 : Leftover blown-up balloons = 247 balloons

Note: The question is incomplete. The complete question is given below:

A clown bought 5 bags of round balloons with 24 balloons in each bag. the clown also bought 3 bags of long balloons with 36 balloons in each bag.

Part 1

How many more round balloons than long balloons did the clown buy?

Part 2 out of 2

The clown also bought 3 bags of heart-shaped balloons with 14 balloons in each bag. when the clown blew up all of the round, long, and heart-shaped balloons, 23 balloons burst. How many blown-up balloons were left? explain your answer.

Step-by-step explanation:

Step 1 : Finding the total number of each balloon

Round balloon = 5 × 24 = 120 balloons

Long balloons = 3 × 36 = 108 balloons

Heart-shaped balloons = 3 × 14 = 42 balloons.

Part 1:

Number of extra round balloons that long balloons = 120 - 108

Number of extra round balloons that long balloons = 12 balloons

Part 2:

Total number of balloons = 120 + 108 + 42 = 270 balloons.

Number of burst balloons = 23

Leftover blown-up balloons = 270 - 23 Leftover blown-up balloons = 247 balloons

The equation represents from starting position of 3 meters below sea level, the fish is descending 7 meters per second. Then the correct option is C.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

A fish is swimming at a constant rate toward the ocean floor. The equation y = – 7x – 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.

The equation represents from starting position of 3 meters below sea level, the fish is descending 7 meters per second. Then the correct option is C.
