Answer:
4
Step-by-step explanation:
All the sides of an equilateral triangle are equal, hence the perimeter is expressed as P = 3s
s is one of the side length
Given DE = 5x - 8
P = 3DE
P = 3(5x-8)
36 = 3(5x-8)
36/3 = 5x-8
12 = 5x - 8
5x = 12+9
5x = 20
x = 20/4
x = 4
Hence the value of x is 4
-7(6a - 3) - 2a = -27 + 4a

The perimeter of a triangle is 27. Each side of the triangle has length 2x-3. What is the value of x?
Answer:
x=6
Step-by-step explanation:
To find the perimeter of the triangle you need to add up all the sides, so if all the sides are 2x-3 the equation will look like this;
2x-3+2x-3+2x-3=27
which when combining like terms will leave it to be;
6x-9=27
Than move all the factors besides x over to the right side;
6x-9+9=27+9
6x = 36
6x/6 = 36/6
x = 6
so your answer will be x=6

2x - 2y = 2
2x + y = 11
The solution is?
Answer:
x = 4, y = 3.
Step-by-step explanation:
2x - 2y = 2
2x + y = 11 Subtract:
-3y = -9
y = -9/-3
y = 3
Plug y = 3 in equation 1:
2x - 2(3) = 2
2x - 6 = 2
2x = 2 + 6 = 8
x = 4.

Which expression is equivalent to 7(y - 8)?
Answer:
In this question , we have to find the equivalent expression.
Step-by-step explanation:
To find the equivalent expression of a fraction, we can either multiply numerator and denominator by same variable or same number, or we can divide both numerator and denominator by same number or same variable .
So if we multiply both numerator and denominator by 2, we will get 14/16
Step-by-step explanation:
7(y-8) = 7y-7(8) = 7y- 56

Answer:
3/32
Step-by-step explanation:
The first question should be 3/8 as there are 3 "1"s on the spinner. The answer to the last one is "3/32". You take the 3/8 chances to get a one and multiply that by 1/4 to get a "B". Once you multiply you get .09375 which is 3/32 when converted. Please let me know if this is incorrect.

What is the result when the number 27 is increased by 1.6%?
Answer:
27.432
Step-by-step explanation:
27 = 100%
divide by one hundred to get one percent
0.27 = 1%
Divide this by two to get 0.5%
0.135 = 0.5%
Divide by 5 to get 0.1%
0.027 = 0.1%
Add
0.27 + 0.135 + 0.027 = 0.432 =1.6%
Add 0.432 to 27
27.432

posting this again because i didn’t get any help from the last post! please help! it’s due soon and i will mark you as brainliest
Answer:
p(x): y-intercept is 4; the base is 3; the equation is p(x) = 4(3^x)
q(x): y-intercept is 4; the base is 2; the equation is p(x) = 4(2^x)
Step-by-step explanation:
The y-intercept of both graphs is 4
The standard exponential function equation is
y = ab^x
We need to find a and b for each function.
For each graph, we use two points to find a and b in the standard exponential function equation.
p(x)
y = ab^x
Use point (0, 4)
4 = ab^0
4 = a * 1
a = 4
y = 4(b^x)
Use point (1, 12)
12 = 4(b^1)
b = 12/4
b = 3
The base is 3.
p(x) = 4(3^x)
q(x)
y = ab^x
Use point (0, 4)
4 = ab^0
4 = a * 1
a = 4
y = 4(b^x)
Use point (1, 8)
8 = 4(b^1)
b = 8/4
b = 2
The base is 2.
q(x) = 4(2^x)

if cot a =5/12 then find the value of cosec A
Answer:
cosec A = 13/12
Step-by-step explanation:
Mathematically, we want to find the value of cosec A
sides 5,12 and 13 represent a Pythagorean triple. This means the last side of the right-triangle that contains 5 and 12 is 13
cot is the ratio of the adjacent to the opposite
Hence ; 5 represents the adjacent while 12 represents the opposite
cosec is the inverse of sine which is the hypotenuse to the opposite ratio
So, we have ;
cosec A = 13/12
