Hey there!
2x + 7 = 27
2x = 20
x = 10
3x + 1 = 28
3x = 27
x = 9
The values for both of these equations are 9 and 10; therefore, the answers are not equivalent.
I hope this helps!
Answer for 4a. 25(n + 6)
Reason
The product (means to multiply)
Six more than a number (n + 6)
And 25 (other multiplier)
Expression is 25(n+ 6)
If it’s 5 times you would multiply 8000 x 5 which is 40,000.
The situation can be modeled by a geometric sequence with an initial term of 284. The student population will be 104% of the prior year, so the common ratio is 1.04.
Let \displaystyle PP be the student population and \displaystyle nn be the number of years after 2013. Using the explicit formula for a geometric sequence we get
{P}_{n} =284\cdot {1.04}^{n}P
n
=284⋅1.04
n
We can find the number of years since 2013 by subtracting.
\displaystyle 2020 - 2013=72020−2013=7
We are looking for the population after 7 years. We can substitute 7 for \displaystyle nn to estimate the population in 2020.
\displaystyle {P}_{7}=284\cdot {1.04}^{7}\approx 374P
7
=284⋅1.04
7
≈374
The student population will be about 374 in 2020.
Answer:
The other sides of triangles are 8.72 in and 8.72 in
Step-by-step explanation:
In a triangle ABC. Please find the attachment for figure.
Side BC=a = 10 in
Using sine law of trigonometry,
Substitute the given value into formula.
Cross multiply and we get
in
It is a isosceles triangle. Therefore, b=c=8.72 in
Hence, The other sides of triangles are 8.72 in and 8.72 in
