Step-by-step explanation:
Robert is serving 16 drinks to his friends. Three times as many friends are drinking lemonade as tea, and 4 are drinking water. How many of each type of drink does Robert serve?
Answer:
9 lemonade, 3 tea, 4 water
Answer: Robert should serve 3 for tea, 9 for lemonade, and 4 for water.
Step-by-step explanation:
Since you don't know how many friends are drinking lemonade or tea, you should give them variables.
x = amount of friends drinking tea
3x = amount of friends drinking lemonade
We already know how many are drinking water, so there's no need for a variable.
Then, make an equation:
x + 3x + 4 = 16
Simplify:
4x + 4 = 16
Isolate the variable by subtracting 4 from both sides:
4x = 12
Isolate the variable by dividing both sides by 4:
x = 3, so 3 friends are drinking tea
3x = 9, so 9 friends are drinking lemonade
Double check the work by replacing the variables with their actual numbers:
3 + 9 + 4 = 16
Simplify:
16 = 16
Therefore, the answer is correct.

The value, y, in dollars of an autographed basketball after x years can be represented by the function y=4000(1.05)x.
What is the value of the basketball after 5 years to the nearest dollar?
Answer:
I took the test!!
Step-by-step explanation:
Pit this in your calculator exactly like this 4,000(1.05)^5 and you get the answer 5,105.12625. So round your answer to the nearest dollar, which is 5,105.

Which point on the coordinate plane below is (-9, 3)?
Point D
Point C
Point B
Point A
Answer:B
Step-by-step explanation: x is -9 and y is 3
Since it’s negative you’d go left by 9 blocks and the y is positive so you go up 3
Answer:
The answer is point B
Step-by-step explanation:
I know this because (-9, 3) seems to be located in quadrant 2 because in quadrant 2 along the x-axis it is negative and along the y-axis it is positive. So, when l look in quadrant 2 there seems to be only one point, point B, which if you look at it is 9 units to the left and 3 units upward.
You are having a movie marathon. Each movie lasts about 12 hours.
If you want to watch 4 movies, how long will your movie marathon last?
Answer:
Your movie marathon will last 6 hours.
Step-by-step explanation:
This question can be solved using a rule of three.
Each movie lasts hours. How much do 4 movies last?
So
1 movie - 1.5 hours
4 movies - x hours
x = 4*1.5 = 6
Your movie marathon will last 6 hours.
Answer:
48 hours or 2 days
Step-by-step explanation:
There are 4 movies
Each movie lasts 12 hours
4 x 12 or 12 x 4 equals 48
The marathon lasts 48 hours

The ratio of rainbow trout to mackinaw released into a lake was 4:7. A total of 682 fish were released. How many were mackinaw?
Answer:
There are 450 trout in the lake.
B - brown trout;
R - rainbow trout.
B : R = 6 : 9 = 2 : 3
B = 2 t
R = 3 t
2 t + 3 t = 5 t
5 t = 450
t = 450 : 5
t = 90
R = 3 * 90 = 270
Answer:
There are 270 rainbow trout in the lake.

Bruce bought 5/8 ounces of peppers and 2/3 ounces of onions. How many more ounces of onions did he buy compared to peppers?
Answer:
The price of one pound of bell peppers is $0.6.
Step-by-step explanation:
This problem is equivalent to the following:
"if 10 oranges cost $20, how much does 1 orange cost? "and the answer to that question is:
price of 1 orange = $20/ 10 oranges = $2 per orange.
Put simply, we divided the total price by the total number of items, and we shall do the same thing for the case of bell peppers:
price of 1 pound = $1.25/ 2.5 pounds = $0.5/ pound.
The price for 1 pound of bell peppers is $0.5.

Answer:
542, 543, 544, 545.
Step-by-step explanation:
Divide 2174 by 4 = 543.5
(because there are 4 integers) 543.5 is not an integer.
However, one of the four integers is 543.
Write down four consecutive numbers that include 543 and add them:
like 541+542+543+544 =. if that is 2174, you have the answer, if it's too low, try moving up one number, like
542+543+544+545 = if it's still too low, move up one number again
543+544+545+546=
You only have to do that a max of 3 times to get the answer.
The four consecutive integers are
542, 543, 544, 545.
good luck, hope this helps :)

A surfboard that has a regular price of $150 is on sale at a 40% discount. What is the sale price with a 9% tax?
Answer:
$98.10

90 increase 9% =
90 × (1 + 9%) = 90 × (1 + 0.09) = 98.1
