Answer:
16n+12
Step-by-step explanation:
If all four sides measure 4n+3, then the perimeter is 4 times the length of each side. 4(4n+3) = 16n + 12 = perimeter
if a triangle has a area of 42 cm^2 and a base of 8 cm, what is the height?
show work plsssss
Answer:
The height would be 10.5 cm
Answer:
hb=10.5cm
Step-by-step explanation:
Area of triangle = 1/2(height x base)
The problem states that base is 8 cm greater than the height; therefore, base-8 = height.
A = 1/2(b*h)
42 = 1/2(b*[b-8])
84=(b^2-8b)
rearrange to
b^2 - 8b -84
factor to
(b+8)(b-14)
Therefore, b = -8 cm which makes no sense and
b = +14 cm
and height = 14-8 = 6
Check:
1/2(b*h) = area
1/2(14*6) = 1/2(84)=42

What is the value of x?
[Art not to scale.]
Ox=23
Ox=35
Ox=58
Ox=93
The value of x in the given figure is 93 degrees.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Let us find the interior angle of the triangle SQR.
By angle sum property the sum of three angles is 180 degrees.
35+58+x=180
93+x=180
Subtract 93 from both sides
x=180-93
x=87 degrees
Now let us find the x degrees.
The sum of interior angle of vertex Q and exterior angle is 180 degrees
87+x=180
x=180-87
x=93 degrees
Hence, the value of x in the given figure is 93 degrees.

(9c+8)+(5x-2)+(3y+7)
Answer:
9c + 5x + 3y + 13
Step-by-step explanation:
you can't combine any of the numbers wwith variables because the variables aren't the same but you can combine the other numbers (8, -2, 7)
8 - 2 = 6
6 + 7 = 13
put the equation back together but instead replace the 8, -2, and 7 with 13 giving you

Answer:
m=22
Step-by-step explanation:
The angles of the triangle will be equal to 180.
m + 5m + m+26 = 180
Combine like terms
7m+26=180
Subtract 26 on both sides
7m=154
Divide by 7
m=22
Answer:
m=22
Step-by-step explanation:
Triangle has 180 degrees in total
m+5m+(m+26)=180
solve
6m+m+26=180
7m=180-26
7m=154
m=22
Sage and Tom started the month with the same number of talk minutes on their cell phones. Sage talked for 7 minutes with her dad. Tom talked for 4 minutes with a friend and 3 more minutes with his mom. Do Sage and Tom have the same number of talk minutes left on their cell phone plans? Write an algebraic expression to represent the number of minutes Tom has left. Question 1
Answer:
a. Sage and Tom have the same number of talk minutes left on their cell phone plans.
b. y = x - 7
Explanation:
Sage talked for 7 minutes with her dad.
Tom talked for 4 minutes with a friend and 3 more minutes with his mom which means he spoke for :
= 4 + 3
= 7 minutes
They both spoke for 7 minutes and therefore have the same amount of time left.
Algebraic expression:
Assuming the time Tom started with is denoted by x and the time he is left with is denoted by y.
The expression is:
y = x - 7

look down
Step-by-step explanation:
OK so u take something like 9/3 and then ask how many times the 3 goes into the 9 and that is your whole number. whatever is left is your top of the fraction and the bottom stays the same hope this helped
Answer:
To make an improper fraction into a mixed fraction:
1. Divide the numerator by the denominator
2. Write down the whole number answer
3. Then write down any remainder above the denominator
Example:
Turn 8/3 into a mixed fraction.
8 ÷ 3 = 2 R2
So... 2[tex]\frac{2}{3}[/tex]
To make a mixed fraction into an improper fraction:
1. Multiply the whole number part by the fraction's denominator.
2. Add that to the numerator.
3. Then write the result on top of the denominator.
Example:
Turn 4[tex]\frac{6}{7}[/tex] into an improper fraction.
4 x 7 = 28
28 + 6 = 34
So... [tex]\frac{34}{7}[/tex]

Dana is planning to drive 400 miles from
New York to Boston and back. Dana's
hybrid car can travel 50 miles on 1 gallon
of fuel. Biodiesel fuel costs $4.45 per
gallon.
Part A: How many gallons of fuel does
Dana need to purchase for the 400-mile
trip? Explain your reasoning.
Part B: Dana can take a high-speed train
to Boston instead of driving. A round-trip
train ticket costs $95. Is it cheaper for
Dana to take the train or to drive? How
much cheaper? Explain your reasoning.
Answer:
A. 8 gallons
B. Drive by car is $59.4 cheaper than travel by train
Step-by-step explanation:
According to the scenario, given data are as follows,
Total drive = 400 miles
Total drive per gallon = 50 miles
Fuel cost per gallon = $4.45
A. So, Total fuel required to drive 400 miles can be calculated as follows,
Total fuel required = Total drive ÷ Total drive per gallon
By putting value, we get,
Total fuel required = 400 ÷ 50
= 8 gallons
B. Total cost if drive by car = 8 gallons × $4.45 = $35.6
Cost if travel by train = $95
Hence it is clearly shows that drive by car is much cheaper than travel by train.
Cost saved by travel by car = $95 - $35.6 = $59.4
So, drive by car is $59.4 cheaper than travel by train.

The probability that a student chosen at random from a class has brown
hair is 7/13
The probability that they have ginger hair is 5/26
What is the probability that a student chosen from the class at random has
either brown hair or ginger hair?
Give your answer as a fraction in its simplest form.
Answer:
5/26+7/13
5/26+14/26
19/26
The probability that a student chosen from the class at random has either brown hair or ginger hair is 19/26.
Given that, the probability that a student chosen at random from a class has brown hair is 7/13 and the probability that they have ginger hair is 5/26.
Probability that student have either brown hair or ginger hair
= 7/13 + 5/26
= 14/26 + 5/26
= (14+5)/26
= 19/26
Therefore, the probability that a student chosen from the class at random has either brown hair or ginger hair is 19/26.

The perimeter of a certain hexagon is 14.7 centimeters. Five of the sides have the same
length of n centimeters, while the one side has a length of 1.9 centimeters, as shown
below.
Answer:
The value of n is n = 2.56 cm
Option D is correct option.
Step-by-step explanation:
Perimeter of hexagon = 14.7 cm
Five sides have length = n cm
One side has length = 1.9 cm
We need to find value of n
The formula used to find Perimeter of hexagon is : [tex]Perimeter = Sum\;of\:all\:sides[/tex]
We can write:
[tex]Perimeter = Sum\;of\:all\:sides\\14.7=5n+1.9\\[/tex]
Because 5 sides have length = n so, 5n and one side has length = 1.9
Now, solving to find n
[tex]14.7-1.9=5n\\5n=12.8\\n=\frac{12.8}{5}\\n=2.56[/tex]
So, The value of n is n = 2.56 cm
Option D is correct option.
