2x+1=5x-44 that would be your equation

next start to simplify 

subtract 1 from both sides so you are left with 2x=5x-45

then subtract 5x from both sides and you have -3x=-45

then finally divide -3 from -45 to get x=15

Answer:

PQ=31\ units

Step-by-step explanation:

we know that

In this problem Q is the midpoint of PR

so

PQ=QR

we have

PQ=2x+1 -----> equation A

QR=5x-44 -----> equation B

equate equation A and equation B

2x+1=5x-44

solve for x

5x-2x=1+44

3x=45

x=15

Find the value of PQ

PQ=2x+1 ------> PQ=2(15)+1=31\ units

kondaur [170]

Answer:

The last two terms of the expression are

  ----+8r^2s^4-3r^3s^3

Both the last terms has variable of degree equal to (2+4=6) and (3+3=6).So, the first term must have degree greater than 6.

Correct Options are

 1.\rightarrow 3r^4s^5\\\\2.\rightarrow -r^4s^6

A marine biologist is studying the growth of a particular species of fishShe writes the following equation to show the length of
Doss [256]

Answer:

The given equation is:

f(m) = 3(1.09)^m

where 'f(m)' represents the length of the fish after 'm' months.

Domain is considered as a set of all values of input. In this question, the input is number of months. The input should starts at 0 which will show the initial height and then as the number 'm' increases, the value of f(m) also increases.

Thus, the domain can be defined as m ≥ 0

y-intercept occurs at m=0. It means the height of the fish after 0 months, which can also be considered as initial height.

Calculate the value of function for m=2 and m=8

For m=2, f(2) = 3.564

For m=8, f(8) = 5.978

Average rate of change = (5.978-3.564) / (8-2)

Average rate of change = 0.402

It means the fish grows about 0.402cm each month in between 2 to 8 months

vovikov84 [41]
Given:
4/5 as many students who do not wear glasses as those who wear glasses.
60 students wear glasses.

Find the total number of students in the grade.

60 * 4/5 = (60 * 4)/5 = 240 / 5 = 48 students who do not wear glasses.

60 w/ glasses + 48 w/o glasses = 108 total number of students.
