A hot-air balloon rises 150 feet every 5 second. Which equation represents the relationship between time and height?
Answer:
y=30x
Step-by-step explanation:
the slope would be the change in height/time so 150/5 which is 30feet/sec
thus using the form y=mx+b and assuming the balloon started on the ground (0) then y=30x

the value of y is 20% more than the value of x. the ratio of x:y = 5
Answer:
x:y = 5:6
Step-by-step explanation:
y = x(20/100) + x
y = x (1/5) + x
Factorize X
y = x (1/5 + 1)
y = x (6/5)
5y = 6x
-----------------------------
ratio x:y = 5:6
The ratio is x:y = 5:6.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same sort and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is expressed as a: b.
Given:
value of y is 20% more than the value of x
So,
y = x(20/100) + x
y = x (1/5) + x
y = x (1/5 + 1)
y = x (6/5)
5y = 6x
Hence, the ratio is x:y = 5:6.

Solve for x. Show each step of the solution. 4.8(9-x)+36=102-2.5(2x+2)
4.8(9−x)+36=102−2.5(2x+2)
First we will expand the equation by removing those parenthesis. We can use the distributive property. An example is 4.8(9-x) is 43.2-4.8x
43.2-4.8x+36 = 102-5x-5
Then we simplify each side by combining like terms.
79.2-4.8x=97-5x
Then to isolate the variable, we will subtract 79.2 on both sides.
-4.8x=17.8-5x
Then add 5x on both sides
0.2x=17.8
Finally, divide both sides by 0.2 and you get
x=89
Answer:
x =89
Step-by-step explanation:
4.8(9-x)+36=102-2.5(2x+2)
Distribute
43.2 - 4.8x + 36 = 102 - 5x -5
Combine like terms
79.2 -4.8x = 97-5x
Add 5x to each side
79.2 -4.8x+5x = 97-5x+5x
79.2 + .2x = 97
Subtract 79.2 from each side
79.2 -79.2+ .2x = 97-79.2
.2x =17.8
Divide by .2
.2x/.2 = 17.8/.2
x =89
is this reletion just a function? Justify your answer. A. Yes, because every x- and y-value is positive. B. no, because two points with the same y-value have different x-values. C. Yes because every x-value corresponds with a single y-value. D. Yes, because the number of x-values is the same as the number of y-values.
Answer:
The element 15 has two arrows pointing to both 7 and 9. This is a clear violation of the requirement to be a function. A function is well behaved, that is, each element in the domain must point to one element in the range. Therefore, this relation is not a function.

Russell has been training for the Emerald Valley Race. The first week he trained, he ran 5 days and took the same two routes each day. He ran 2 miles around the football field before
school and ran a longer route through his neighborhood after school. By the end of the week,
Russell had run a total of 30 miles.
Which equation can Russell use to find how many miles, x, he ran each day after school?
5x + 2 = 30
2(x + 5) = 30
5(x + 2) = 30
2x + 5 = 30
How many miles did Russell run each day after school?
Write your answer as a whole number or a simplified fraction.
miles
In maths, Distance is described as the quantity of space between two points, and further calculation can be defined as follows:
Given Expression:
[tex]5x + 2 = 30\\\\2(x + 5) = 30\\\\5(x + 2) = 30\\\\2x + 5 = 30[/tex]
To find:
distance=?
Solution:
[tex]5\ days\ \begin{cases} & \text{ if } \text{before school 2 miles} \\ & \text{ if } \text{after school x miles} \end{cases}[/tex]
[tex]\therefore 5(x+2)=30\\\\[/tex]
[tex]\bold{5(x+2)=30}\\\\\bold{5x+10=30}\\\\\bold{5x=30-10}\\\\\bold{5x=20}\\\\[/tex]
[tex]\bold{x=\frac{20}{4} }\\\\\bold{x=4}[/tex]
Therefore, the final answer is "4 miles".

The distance that a person drives at a constant speed varies directly with the amount of time they have been
driving. If, at a particular speed, a person drives 107 miles in two hours, then how far will they drive, at the
same speed, in 14 hours?
Answer:
749 miles
Step-by-step explanation:
I divided 107 by 2 and then multiplied that by 14
a person drives 53.5 at that particular speed so they keep driving that amount of miles each hour so it's 749
The distance they will drive, at the same speed, in 14 hours is 749 miles.
Given the following data:
Distance A = 107 milesTime A = 2 hoursTime B = 14 hoursTo find how far (distance) will they drive, at the same speed, in 14 hours, we would apply direct proportion:
By using direct proportion:
107 miles = 2 hours
X miles = 14 hours
Cross-multiplying, we have:
[tex]2X = 107 \times 14\\\\2X = 1498\\\\X = \frac{1498}{2}[/tex]
X = 749 miles

a party rental company has chairs and tables for rent. the total cost to rent three chairs and five tables is $52. The total cost to rent 9 chairs and 7 tables is$86. what is the cost to rent each chair and each table?
Answer:
The cost for 1 chair is $2.75 and the cost for 1 table is $8.75.
Step-by-step explanation:
Use the elimination method of linear equations to find your answer.
Our equations for this problem are:
3c+5t=52 and 9c+7t=86
Multiply the entire first equation by -3.
-3(3c+5t=52)
Simplify the equation from above:
-9c-15t=-156
Stack the two equations on top of each other and add/subtract:
-9c-15t=-156
9c+7t=86
You should be left with -8t=-70. Simplify this to find the value of t:
t=8.75
Plug the value of t into any of the original equations and solve for c.
3c+5(8.75)=52
Simplify the equation above:
3c+43.75=52
Subtract 43.75 from both sides of the equation:
3c=8.25
Divide both sides by 3 to get your c value:
c=2.75
