Answer:
x = 20
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
3x + 1 + x + 14 + 4x + 5 = 180, that is
8x + 20 = 180 ( subtract 20 from both sides )
8x = 160 ( divide both sides by 8 )
x = 20

The value of $\sqrt{73}$ is between two positive, consecutive integers. What is the product of these two integers?
Answer:
Step-by-step explanation:
What are the two closest square numbers to 73?
64 and 81
[tex]\sqrt{64} \leq \sqrt{73} \leq \sqrt{81}\\8\leq \sqrt{73} \leq 9\\8*9 = 72[/tex]
Answer:
72
Step-by-step explanation:
Since $73$ is between $64=8^{2}$ and $81=9^{2}$, we know that $\sqrt{73}$ is between $8$ and $9.$ Our answer is $8\cdot9=\boxed{72}.$

Plz help and only give the answer! will mark brainliest! TY if u answer
A)The gallons of gas needed to make 320 miles = 24 gallons of gas
Explanation
Step 1: To find the gallons of gas needed to make 1mile
The car uses 15 gallons of gas to make 200 miles.
from this we get,
gallons of gas needed to make 1mile = 15/200 =3/40
Step 2: To find the gallons of gas needed to make 320 miles
Therefore, the gallons of gas needed to make 320 miles = 320 x(3/40) = 24 gallons of gas

There are 28 red pens and 84 black pens in a bag.
Write down the ratio of the number of red pens to the number of black pens.
Give your ratio in its simplest form.
Answer:
1/3
Step-by-step explanation:
The ratio can be written as a fraction. This would be 28/84. You simplify ratios just like how you simplify a fraction. 28x3 is actually 84, so the answer in simplest form is 1/3.
Hope this helps and have a great day!! []~(^▽^)~*
The ratio of the number of red pens to the number of black pens in simplest form is, 1 : 3.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
There are 28 red pens and 84 black pens in a bag.
Here, Number of red pens = 28
And, Number of black pens = 84
Hence, The ratio of the number of red pens to the number of black pens is,
⇒ Number of red pens : Number of black pens
⇒ 28 : 84
⇒ 28/84
⇒ 14 / 42
⇒ 1 / 3
⇒ 1 : 3

Answer:
In arithmetic, variables look like letters.
Step-by-step explanation:
As we know that Mathematical arithmetic deals with numbers and certain properties with them.
Some of the main properties between numbers are as follows:
AdditionSubtractionMultiplicationDivisionVariables do not remain constant, so we basically assign a number to a variable with an equal operator denoted by '='.
For example, let us assume a variable x being equal to 7. so it can written as:
[tex]x = 7[/tex]
Let suppose the value of the variable x=7 changes to x=10, then the new value will be:
[tex]x = 10[/tex]
Therefore, the correct answer is:
In arithmetic, variables look like letters.

Simba Travel Agency arranges trips for climbing Mount Kilimanjaro. For each trip, they charge an initial fee of $100 in addition to a constant fee for each vertical meter climbed. For instance, the total fee for climbing to the Shira Volcanic Cone, which is 3000 meters above the base of the mountain, is $400
Let y represent the total fee (in dollars) of a trip where they climbed xxx vertical meters.
Complete the equation for the relationship between the total fee and vertical distance.
Answer:
Step-by-step explanation:
The formula is F(d) = 100+0.10d.
We must find the cost per meter to write the function. We know that the cost to climb a 3000 meter mountain was 400:
400=100+3000(x)
Subtract 100 from each side:
400-100 = 100+3000x-100
300 = 3000x
Divide both sides by 3000:
300/3000 = 3000x/3000
0.10 = x
This is the cost per meter. Using this, we have the formula
F(d) = 100+0.10(d)
Answer:
T(x) = 0.1x + 100Step-by-step explanation:
Total fee is $400Initial one off fee is $100Fee for each meter = xConsidering all the given and the vertical distance of 3000 m we get below equation
400 = 100 + 3000xSolving, we find the fee for each meter:
400 -100 = 3000x300 = 3000xx = 300/3000x = 0.1 dollar per meterSo the equation for total fee including climbing x meters is:
T(x) = 0.1x + 1008.01 × 10^-2 round the coefficient to two decimal places

that equals 0.0801

0.2x+2.7x−8.1=6.9+1.1x
The answer is not x = 83 tho
and don't do it for the points
0.2x + 2.7x - 8.1 = 6.9 + 1.1x
Combine like terms on left side:
0.2x + 2.7x = 2.9x
Now you have:
2.9x -8.1 = 6.9 + 1.1x
Subtract 1.1x from both sides:
1.8x - 8.1 = 6.9
Add 8.1 to both sides:
1.8x = 15
Divide both sides by 1.8:
X = 8.3333 ( round as needed) or as a fraction = 8 and 1/3
Answer:
8.3recurring
Explanation:
0.2x+2.7x =2.9x
rewrite the questions
2.9x-8.1=6.9+1.1x
like terms together. Therefore:
2.9x-1.1x = 1.8x
8.1 will go to the other side of the equal sign. Therefore:
8.1+6.9 = 15
Therefore: 1.8x = 15
x =15/1.8 which is equal to 8.3recurring
