Questions 9 = -1
Questions 10 = -15
Answer:
9. -1
First combine the like terms (-5x and 3x), the move -9x to the other side. That equals 7x. Then move -16 (turn positive) and add it to -23, that equals -7. Divide both sides by 7.
10. 9
Add 1 to -24. Then move -23(turn positive) to the other side. Combine with -5 and you get 18. Then move 6r and subtract it from 8r. Divide both sides by 2.
11. 11
Subtract 7a from 9a= 2a. then add 3a and 2a and move 5a to the other side. Add -5a and 2a = -3a. Divide both sides by -3.
12. 5
Combine the like terms. Move -25 and turn it positive and then add it to 20= 45. Turn -2m positive and add it to 7m. Divide both sides by 9.
13. -5
Use the distributive property on both sides. Move 2k and subtract it from 4k= 2k. Move -8 and add it to -18= -10. Divide both sides by 2.
14. -2
Use the distributive property. Move -5n and add it to -6m= -m. Move 18 and subtract it from 20= 2. Divide both sides by -1.
15. -3
Use the distributive property and combine like terms. Move 4p to the other side and subtract from -7p= -11p. Change the sign of 16 and add to 17= 33. Divide both sides by -11.
16. -13
Use the distributive property (pay attention to signs) and combine the like terms. Move -8v, turn positive, and add to -6v= 2v. Move 14, turn negative, and combine with -12= -26. Divide both sides by 2.

f=vu÷v+t,find v if f=20 and u=5
Answers
Answer:
v=20/3
See IMAGE FOR SOLUTION
In the given expression f = uv /(v+t) value of v in terms of t is *4/3t.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given an expression f = uv /(v+t)
Also given
f = 20
u = 5
Hence, From the expression
f = uv /(v+t)
=> 20 = 5v/(v + t)
Simplifying in the terms of v
20v + 20t = 5v
15v = -20t
v = -4/3t
Therefore, the value of v in the given expression is -4/3t.

An aircraft carrier left Hawaii traveling west seven hours before a container
ship. The container ship traveled in the opposite direction going 5 km/h slower
than the aircraft carrier for six hours after which time the ships were 540 km apart.
Find the aircraft carrier's speed.
Answers
Answer:
so speed of aircraft carrier is 30. thank you
The speed of an aircraft carrier is 30 km/h.
What is Speed?speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.
Given, An aircraft carrier left Hawaii traveling west seven hours before a container ship. The container ship traveled in the opposite direction going 5 km/h slower than the aircraft carrier.
Since,
Speed = distance/time
time is 13 hours, 7 hours before the container ship left then the 6 hours container traveled.
Let "s" be the speed of the aircraft carrier
=> d = 13s
Container ship:
time is 6 hours
speed is 5 km/h slower, so s-5
=> d = 6(s-5)
Since they are going in opposite directions, add up the distances to find how far apart they are
=> 13s + 6(s-5) = 540
Now solve for s-
=> 13s +6s -30 = 540
=> 19s = 570
=> s = 30
therefore, the Aircraft carrier was traveling at the speed of 30 km/h and the container ship at the speed of 25 km/h.

Please, someone help me with this task, I am stuck
Answers
Answer: the equation is y = -5x/6 - 2
Step-by-step explanation:
x1 = -6
y1 = 3
x2 = 6
y2 = -7
now
m(slope) = rise/run = (y2-y1)/(x2-x1)
= (-7-3)/(6-(-6))
= -10/12
= -5/6
now
y = mx+ b
-7 = m*6 + b
or, -7 = -5/6*6 + b
or, -7 = -5 + b
so, b = -2
now
y = mx +b
y = -5/6*x + (-2)
y = -5x/6 - 2
Answer:
y = -5/6 × x - 2 = -5x/6 - 2
Step-by-step explanation:
we have two marked points with seemingly integer coordinates for x and y.
the equation of a line is
y = a×x + b
now, we only need to put the x and y values pairs into this equation and calculate a and b.
P1 = (-6, 3)
P2 = (6, -7)
based on what I can see on the picture.
starting with P1
3 = a×-6 +b
b = 3 + a×6
then with P2
-7 = a×6 + b = a×6 + 3 + a×6 = a×12 + 3
-10 = a×12
a = -10/12 = -5/6
=>
b = 3 + a×6 = 3 + -5/6 × 6 = 3 - 5 = -2
so, the line equation is
y = -5/6 × x - 2 = -5x/6 - 2

HURRY PLEASE HELP. Point J is located at – 4. Points K and L are each 5 units away from Point J. Where are K and L located?
Answers
Answer:
It depends in which direction "away" means. If they are five units to the right then the answer should be 1. if they are 5 points away to the left then the answer would be -9.
Step-by-step explanation:
Basically it depends,
if its indicating to the right the equation would be=
-4+5=x
which to do this negative cancells out its positive, so you can just subtract their absolute values. 5-4=1. And to know which symbol it has you just indicate which factor has the greated absolute value. (aka 5 which is positive so the answer should be positive).
-----------------------------
if its to the left then the equation would be=
-4-5= x
(negative four subtracted by four)
and the easier way to do this would be to turn this equation into addition.
the new equation shall be: -4+(-5)=-9 since they are both negative integers the sum should be negative.

What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths, and so onThe tens mean multiply by 10The tenth means the tenth part of that digit which is that digit divided by 10Given 6 tenths, 2 hundredths, 8 thousandths, this can be written in the standard form as,

You worked 14 hours last week and earned a total of $124 before taxes. Your job as a lifeguard pays $10 per hour and your job as a cashier pays $8 per hour. How many hours did you work at each job
kennedy look, i got my phone back and i wanna talk text me 850 533 1209, sorry anybody that are answering pls dont report im putting extra points ok
Answers
Step-by-step explanation:
let :
the job as lifeguard = A
the job as cashier = B
making 2 equations as follows :
(1) A+B = 14 ==> A = 14-B
(2) 10A + 8B = 124
substitute A (equation (1)) into equation (2) :
10(14-B) + 8B = 124
140 -10B +8B = 124
140- 2B = 124
140-124 = 2B
16 = 2 B
B = 8
A = 14-8 = 6
so, as a lifeguard = 6 working hours
and as a cashier = 8 working hours
Answer:
Step-by-step explanation:
Let the lifeguard hours = x
Let the cashier hours= y
x + y = 14
10*x + 8*y = 124 Multiply the top equation by 8 Put it under here.
8x + 8y = 112 Subtract
2x = 12 Divide by 2
x = 6
He worked 6 hours as a lifeguard.
x + y = 14
6 + y = 14 Subtract 6 from each side
y = 14 - 6
y = 8
He worked 8 hours as a cashier.
check
6*10 = 60
8 * 8 = 64

Write the equation of circle with diameter of 10 units centered at (- 2, 1) .
Answers
Answer:
[tex](x+2)^2 + (y-1)^2 = 25[/tex]
Step-by-step explanation:
We want to write the equation of a circle with a diameter of 10 units centered on (-2, 1).
Recall that the equation of a circle has the standard form:
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Where (h, k) is the center and r is the radius.
Since our diameter is 10, our radius is 5.
And since the center is at (-2, 1), h = -2 and k = 1.
Substitute:
[tex]\displaystyle (x - (-2))^2 + (y - (1))^2 = (5)^2[/tex]
And simplify. Hence, our equation is:
[tex](x+2)^2 + (y-1)^2 = 25[/tex]
