Answer:

a. one solution

b. infinetly many solutions

c. one solution

d. no solution

Step-by-step explanation:

brainliest plz :)

The solution of equations are one solution, infinitely many solutions, one solution and no solution.

We are given that;

The four equations

Now,

To determine whether an equation has no solution, one solution, or infinitely many solutions, we can try to solve for the variable and see what happens.

Let's apply this method to each equation:

a. 8p + 1 = 4p + 2

4p + 1 = 2

Subtracting 1 from both sides, we get:

4p = 1

p = 1/4

This is a consistent result, so the equation has one solution: p = 1/4.

b. -6p + 7 = 7 - 6p

Adding 6p to both sides, we get:

7 = 7

This is an identity, so the equation has infinitely many solutions. Any value of p will satisfy the equation.

c. p + 9 = 2p - 3

Subtracting p from both sides, we get:

9 = p - 3

Adding 3 to both sides, we get:

12 = p

This is a consistent result, so the equation has one solution: p = 12.

d. 5p + 3 = 5p - 1

Subtracting 5p from both sides, we get:

3 = -1

This is a contradiction, so the equation has no solution.

Therefore, by the equation answer will be one solution, infinitely many solutions, one solution and no solution.

But we want to know how long it would have taken her for the whole job not just part of it
he works twice as fast as she does so the job that takes him 10 hours alone would take her 20 hours alone.

2) jessica and cynthia work in a pet shop.
it takes jessica 6 hours to groom all the pets but cynthia needs 8 hours to groom them.
if jessica starts to groom 1 hour before cynthia joins, how long will it take them to finish?
:
let t = time it takes them to finish (C's working time)
then
t+1 = J's working time
let 1 = completed job (all pets groomed)
:
A shared work equation, each does a fraction of the job, the two fractions add up to 1
%28%28t%2B1%29%29%2F6 + t%2F8 = 1
Multiply by the least common multiple of 6 and 8, 24. cancel the denominators
4(t+1) + 3t = 24
4t + 4 + 3t = 24
4t + 3t = 24 - 4
7t = 20
t = 20/7
t = 26%2F7 hrs, which is: 2 + 6%2F7*60 = 2 hrs 51.43 min to finish the job

3) math club takes 40 minutes
science takes 50 minutes.
rate * time = quantity
quantity = 1 set up of the tables.
rate for math club is 1/40 of all the tables in 1 minute.
rate for science club is 1/50 of all the tables in 1 minute.
math club works for 10 minutes.
rate * time = quantity
1/40 * 10 = 10/40 = 1/4 of the tables are already set up by the math club.
there are 3/4 of the tables that still need to be set up.
rate * time = quantity
the rates of the math club and the science club are additive.
(1/40 + 1/50) * time = 3/4 of the tables that still need to be set up.
common denominator is 200.
(5/200 + 4/200) * time = 3/4.
9/200 * time = 3/4
time = 3/4 * 200/9 = 600 / 36 = 16 and 2/3 minutes.
total time required is 10 + 16 + 2/3 minutes = 26 + 2/3 minutes.
how to check.
10 minutes is used to do 1/4 of the tables.
16 + 2/3 minutes is used to do the remaining 3/4 of the tables.
combined rate of math and science club is 9/200 of the tables in 1 minute.
math club rate of 1/40 * 10 = 10/40 = 1/4 of the tables.
combine rate of 9/200 * (16 + 2/3) = 9/200 * 50/3 = 450/600 = 9/12 = 3/4 of the tables.
1/4 + 3/4 = 1 = all of the tables.

Parson City Middle School has 1,340 students. About 38% of the students are in the seventh grade. About how many seventh-graders attend Parson City Middle School?

Answers

Answer: About 509 seventh-graders attend Parson City Middle School.

Step-by-step explanation:

Total students in the school = 1,340

About 38% of the students are in the seventh grade.

Number of students in the seventh grade = 38% of (Total students in the school)

= 0.38 x (1340) [38%= 0.38]

= 509.2 ≈ 509

Hence, About 509 seventh-graders attend Parson City Middle School.

[tex]m\angle CBD=35^{\circ}[/tex]

Step-by-step explanation:

Since there are [tex]180^{\circ}[/tex] on each side of a line and [tex]\angle ABC[/tex] is marked as a right angle, [tex]m\angle CBE=180-90=90^{\circ}[/tex].

[tex]m\angle CBE=m\angle DBE+m\angle CBD[/tex], and [tex]m\angle DBE[/tex] is given as [tex]55^{\circ}[/tex].

Therefore, we can plug in our values and solve:

[tex]90=55+m\angle CBD,\\m\angle CBD=\fbox{35^{\circ}$}[/tex].

Line segment JK is divided by point L in the ratio of 3:2. Endpoint J is at (-16, 2) and point L is at (-15, -20). What are the coordinates of endpoint K?

Answers

9514 1404 393

Answer:

K(-14 1/3, -34 2/3)

Step-by-step explanation:

The division ratio says ...

(L -J)/(K -L) = 3/2

2(L -J) = 3(K -L)

5L -2J = 3K

K = (5L -2J)/3

K = (5(-15, -20) -2(-16, 2))/3 = (-75+32, -100-4)/3 = (-43/3, -104/3)

K = (-14 1/3, -34 2/3)
