Answer:
50 minutes (I think)
Step-by-step explanation:
A= 800 - 6m
B = 1000 - 10m
800 - 6m = 1000 - 10m
4m = 200
50 = m

4x-9=7x+12
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

The ratio of soccer players to baseball players on two school teams is 4 to 7. Which of the following could be the number of players on each team?
A.
12 soccer players and 15 baseball players
B.
12 soccer players and 21 baseball players
C.
16 soccer players and 19 baseball players
D.
16 soccer players and 49 baseball players
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.
What is the ratio of two quantities?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.

There are three chests, each of which contains 100 coins. One chest has 100 gold coins, one has 100 silver coins, and the third has an equal split of 50 gold coins and 50 silver coins. Each chest is labelled, but all are mislabeled. You are allowed to pick one coin from just one of the cases, and after this, you must correctly identify each of the three chests. What should you do?
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=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

Find the value of each trigonometric ratio.
A. 3/4
B. 4/3
C. 4/5
D. 5/3
Someone plz answer.....
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°
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. blown-up balloons were left. First, I found the number of heart-shaped balloons, 3 × = . Next, I added that number to the number of round balloons and long balloons, + 144 + 108 = balloons in all. Last, I subtracted the number of burst balloons, so − 23 = balloons left.
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
2x<6
I need help with this equation
Answer:
-3
Step-by-step explanation: Simplifying
2x + 6 = 0
Reorder the terms:
6 + 2x = 0
Solving
6 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 2x = 0 + -6
Combine like terms: 6 + -6 = 0
0 + 2x = 0 + -6
2x = 0 + -6
Combine like terms: 0 + -6 = -6
2x = -6
Divide each side by '2'.
x = -3
Simplifying
x = -3
Answer:
2x < 6
=> x < 6/2
=> x < 3

2. 2x + y = -4
5x + 3y = -6
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

Elias has read 18 pages of a book. He will continue to read at an average rate of 4 5 5 4 page per minute. The total number of pages (p) Elias reads after m minutes can be represented by the equation p = 4 5 m + 18 p= 5 4 m+18. How many minutes will it take Elias to read a total of 39 pages?
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
