Answer:
Step-by-step explanation:
x+2x-10+x+10=180
(-10+10)(2x+x+x)=180
-20+4x=180
-20+20+4x=180+20
4x=200
4x÷4=200÷4

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

|Giving Brianliest| 50+ points|Max had a collection of 1,000 movies at the beginning of the summer. After the summer, Max had traded some of his movies and now he has only 750 movies.
What is the percent decrease of his movie collection?
Answer:3/4
Step-by-step explanation:duh
To find the percent decrease of Max's movie collection, we need to find the difference between his original collection and his new collection, divide that by his original collection, and then multiply by 100 to express the answer as a percentage.
The difference between his original collection and his new collection is:
1,000 - 750 = 250
So the percent decrease is:
(250 / 1000) x 100% = 25%
Therefore, Max's movie collection decreased by 25%.
Yasin has tried to work the size of the angle marked g in the regular decagon below, using the fact that exterior angles sum to 360°. His workings are shown below.
a) Write a sentence to explain what Yasin has done wrong.
b) What is the size of angle g? Show all your workings.
well, Yasin is correct, the exterior angles are all 36° each, however "g" is including more than just that, Check the picture below.
Answer: 36 is wrong
Step-by-step explanation: 360 - 36 = 324 degrees
Three people hiked the same 1 mile trail. The distance for each hiker is reperesented in the drawing. Show about where the 1 mile mark should be on each drawing.Explain
Answer:
Okay, so for the first line, measure the distance between the start and the 0.5 miles. Then add that distance to the other side of the 0.5 miles and then put a mark.
For the second one measure the distance between the start line and the 0.25 miles and then add that distance to the other side three more times and then put a mark.
And for the last one, use the distance that you used for the second one and put it after the 0.75 mark.

A pitcher contains 14.25 cups of iced tea. You drink 2.5 cups of the tea each morning and 2.25 cups of the tea each evening. When will you run out of iced tea?
Answer:
You will run out of iced tea in 3 days (a total of 3 mornings and 3 evenings)
Step-by-step explanation:
Day 1 - 9.5 cups left
14.25 - 2.5 - 2.25 = 9.5
Day 2 - 4.75 cups left
9.5 - 2.5 - 2.25 = 4.75
Day 3 - 0 cup left
4.75 - 2.5 - 2.25 = 0
Answer: You will run out of iced tea in 3 days
Step-by-step explanation:
2.5 + 2.25 = 4.75
14.25/4.75 = 3
Which inequalities would have an open circle when graphed? Check all that apply.
t Less-than-or-equal-to 25
-2.5 Less-than-or-equal-to m
x > 5.4
One-half less-than x
x > 0
An open circle is used to graph strict inequalities, which means the inequality does not include the value at the boundary. The inequalities that would have an open circle when graphed are:
x > 5.4
One-half less-than x
x > 0
How can you use a number line to compare and order numbers?
Answer:
Going from left to right, numbers increase in value. Going from right to left, numbers decrease in value. It allows you to compare fractions and see if one is greater than, less than, or equal to another.
Answer:work on number lines and do math in number lines they both have same similarities just compare them
Step-by-step explanation:
A juice factory offers its juice in both bottles and cans. A class of students on a field trip decides to compare the numbers of cases of bottled juice and canned juice that are packaged each minute. The students count the number of cases that are packaged on each assembly line over several minutes.
What is the unit rate for canned juice, in cases per minute? Explain how you found this unit rate.
Answer: 50 cases per minute
Step-by-step explanation:
1. Select one of the points on the graph. Let's use (2, 100) in this case.
2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.
3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.

We start with 4 cards. The probability of picking the 4 is 1/4. That card is put back, so we again have 4 cards. The probability of picking the 6 (the number greater than 5) is 1/4.
Therefore, the probability of picking a 4 and then a 6 is (1/4)(1/4) = 1/16.

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day
