Which expression is NOT equivalent to 60 + 18?
6(10+3)
6(10+4)
3(20 + 6
2(30 +9)

Answer:

no solution

Step-by-step explanation:

14a – (2a + 9) = (12a - 18)

Distribute the minus sign

14a – 2a - 9 = (12a - 18)

12a -9 = 12a -18

Subtract 12a from each side

12a -9-12a = 12a-18-12a

-9 = -18

This is not a true statement so there is no solution

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.

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

Answer:

84.04, 30.14 and 55.95

Step-by-step explanation:

First you add the ratios together then divide by 170 and mutliply each answer by the answer of 170 divided by the sum of 3.5, 1.25 and 2.33

Answer:

84.04, 30.14 and 55.95

Step-by-step explanation:

→ Add the ratios together

3.5 + 1.25 + 2.33 = 7.08

→ Divide the answer by 170

170 ÷ 7.08 = 24.01129944

→ Multiply the answer by 3.5 , 1.25 , 2.33

3.5 × 24.01129944 = 84.04

1.25 × 24.01129944 = 30.14

2.33 × 24.01129944 = 55.95

Answer:

slope = - [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

- [tex]\frac{1}{2}[/tex] x - [tex]\frac{3}{4}[/tex] y = 24 ( multiply through by 4 to clear the fractions )

- 2x - 3y = 96 ( add 2x to both sides )

- 3y = 2x + 96 ( divide terms by - 3 )

y = - [tex]\frac{2}{3}[/tex] - 32 ← in slope- intercept form

with slope m = - [tex]\frac{2}{3}[/tex]

Answer:

[tex]p = 1[/tex]

Step-by-step explanation:

[tex]5p - 8(6p - 5) = p - 4[/tex]

[tex] - 43p - 40 = p - 4[/tex]

[tex] - 43p - p = - 40 - 4[/tex]

[tex] - 44p = - 44[/tex]

[tex]p = 1[/tex]

Answer:

[tex] p =\frac{22}{27} [/tex]

Step-by-step explanation:

5p - 8(6p - 5) = p - 4

-5p - 48p + 40 = p - 4

-53p + 40 = p - 4

-53p - p = -4 - 40

-54p = -44

p = 44 ÷ 54

p = 44/54

simplify with factor 2

p = 22/27

Answer:

so speed of aircraft carrier is 30. thank you

The speed of an aircraft carrier is 30 km/h.

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.

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:

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.

The value of the function f(x) for the corresponding x = -6 and x =-11 is equal to 4 and 5 respectively.

The function f(x) = √( -x -2) + 2

The value of x and f(x) are ,

x    :   -2   -3    -6    -11

f(x) :   2     3      ?     ?

Now to find the missing value of f(x) substitute the value of x in f(x) we have,

When x = -6

f(x) = √( -x -2) + 2

⇒ f(x) = √( -( -6) -2) + 2

⇒ f(x) = √(6) -2) + 2

⇒ f(x) = √(4) + 2

⇒ f(x) = 2 + 2

⇒ f(x) = 4

And when x = -11

f(x) = √( -x -2) + 2

⇒ f(x) = √( -( -11) -2) + 2

⇒ f(x) = √(11) -2) + 2

⇒ f(x) = √(9) + 2

⇒ f(x) = 3 + 2

⇒ f(x) = 5

Therefore, the missing values of the function are 4 and 5.

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.

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.
